Walleye Prop

Mercury Racing Lab Finished Bravo I Outboard Propeller.
Mercury Racing Pro Finish Bravo I XS outboard propeller.

You may wonder how we go about testing props. We have a number of our own outboard and sterndrive boats that we use for initial testing. Nevertheless, I’m a firm believer of getting feedback from those who use the product everyday in the real world. Recently, I wanted feedback on performance differences between our Lab Finished Bravo I and Pro Finish Bravo I XS outboard props. My target applications were Walleye and bass anglers.

My colleagues at Mercury (known internally as,  “The Big House” or “Mother Mercury”) provide me access to members of the Mercury Pro Angler Team. Walleye pro, Pat Neu of Forestville, Wisconsin, is my Walleye test guy.

Pat’s Ranger 620 VS dual Console Walleye boat.

Pat runs a 2011 Ranger 620VS Dual Console Walleye boat powered by a Mercury 250 ProXS. He also has a Mercury 9.9 Pro Kicker. The boat was initially rigged and dialed-in with a stock, 21-inch pitch Mercury Tempest  prop. The boat ran great and most people would be satisfied. Not Pat.

Pat’s 250 Pro XS rigged with the Bravo I XS.

Like most pros and enthusiasts, Pat is continuously tweaking his set-up for improvement in overall boat performance. Pat was very receptive to my request for some feedback on our Bravo outboard props on his rig. Mercury Racing is the only propeller manufacturer to provide outboard variants of the Mercury Bravo sterndrive prop (see my blog post, Bravo for Outboards, Yes!).

Pat did back-to-back runs — up to wide open throttle (WOT) — comparing the Lab Finished Bravo I with the Pro Finish Bravo I XS.  Both props were 22-inch pitch. The tests were completed with a full fuel tank, tournament gear (all compartments full) and two anglers in the boat, each weighing approximately 210 lbs.

Test Results:

Bravo I Lab Finished…

RPM @ WOT: 5,850 (full tank of fuel). Speed @ WOT: 57 MPH. Hole shot: 4-5 seconds. Price (MSRP): $1,162.

Bravo I XS…

RPM @ WOT: 5,750 (full tank of fuel). Speed @ WOT: 56 MPH. Hole Shot: 5-6 seconds. MSRP: $708.

Pat noted both Bravo props didn’t care how much weight is in the boat but noticed the engine would tick the rev limitor when the fuel level reached less than half a tank. Pat suggested those who plan to run lighter loads move up to a 23-inch pitch Bravo I XS prop.   As you can see, both props ran very well on Pat’s rig.

If your interested in fishing and getting a turn-key, dialed in rig off the show room floor, a Ranger 620VS Dual Console Walleye boat is a great choice. If your like Pat, and want to get the most out of your boat, you’ll want to consider our Bravo outboard prop options.

  1. I have just placed my order for a 2012 Ranger 620 dual console (ProStaff) with a Mercury ProXS 250 and a 9.9 Pro Kicker. I am also a Silver Mercury sponsorship through Frankie’s marine in Chisago Citry MN. Who determines what prop is installed? Mercury or Ranger? What do you recommend?

    Thank you in advance,
    Tom Bauer

    1. Ranger determines the prop and last I talked to them they prefer the Tempest Plus but they haven’t tried the Bravo I XS propeller… yet. If you’re going to carry a heavy load and you want the throttle response in big water, plus look at the speeds Pat was getting with the Bravo I XS. It’s hard to beat this prop and going with the XS version it will offer you more durability over the Lab. To help your dealer when they contact Ranger here’s the part number for the 22″ 48-831910L60 and for the lighter loads the 23″ pitch 48-831910L80.

      1. Hi. I am from williston nd. I need advise. I have a 2003 triton with a 2003 mercury 250 xs. I have very poor hole shot. I bought the boat & it has a 26 pitch tempest on it. Which prop would you recomend.do you think the brave 1 xs? I run with 2 to 4 people in the boat at times. Thanks.

        1. Nicky,
          What are you getting for wide open throttle RPM and GPS speed? Which model Triton do you have?

    1. I don’t have concrete performance numbers but I can help you with some characteristics of the Rev 4.
      Those that I have talked with running the Rev 4 typically go back to the Tempest.
      The Rev 4 has a long exhaust tube and can benefit planing the boat but the top end numbers haven’t been that great compared to the Tempest.
      We’ve made a Triton/Mercury Pro XS with Rev 4 improve planing and top end by 2 mph compared to the Tempest. Getting there was a challenge, we had to stick allot of Lab Finishing (labor) time into the prop.
      The Lab Finishing makes the Rev 4 too costly and the durability is not as great because the leading edges and blades are thinned.
      The Bravo I XS provides the best bang for the buck. It offers good planing, good top speeds, is durable, doesn’t care how much weight you throw at it and is available at a reasonable price.

  2. The Bravo 1 XS is a pretty cool prop, the exhaust vent hole is massive! The last one we ordered was for a Gambler with a 300 XS that ran the Sport Master and Prop over a rock!

    Did you run the Ranger with the Tempest to get your baseline? How did the boat feel compared to the Tempest? Any major trim differences or jack plate adjustments?

  3. I ran a 21 and 23 Tempest on the boat. The 21 was the correct pitch for me with full tournament loads in warmer water (above 65). The 23 in cold water will work and give you decent top end, but when the water warms I needed to run less pitch to get the boat on plane and achieve the recommended WOT RPM.

    The 22 Bravo 1 XS gave me great hole shot and very strong top end with full tournament loads in the boat. The prop gave the boat more bow lift and a better hole shot. I do not have a jack plate on this boat. I had the motor in the third whole and probably could have dropped it one more hole as I was not throwing much of a rooster tail at full trim.

    You will definitely notice increased performance with this hull running the prop over a Tempest.

  4. I am running a 21 Tempest now at 5700/5730 @ 58mph I see the smallest pitch the Bravo comes in is 22, I ran a 21 Rev 4 and it turned 5500/5600 57mph, the Tempest handles better with a little better holeshot. Got a 21 Bravo in the works?

    1. Run the 22″ pitch Bravo I XS, it’s designed to move you up 1″ of pitch running similar RPM as your Tempest 21.

  5. Scott,
    What is your opinion on running race style Choppers on these monster bass boats? Do you need larger blade surface to deal with the weight of the boats? What characteristic is is unfavorable when you run them?
    Thanks for all your input!

    1. The larger heavier bass boats typically run best with an exhaust tube style prop. The exhaust channeled away from the blades offers faster planing at a lower rpm. The over the hub style prop you have to hammer the throttle hitting 5000+ rpm to bring the boat on plan. The through hub exhaust allows the engine to rev at lower rpm going through no wake zones. The over the hub has all the exhaust wrapping around the blades causing slip, so to do the same no wake zone speed the engine will rev 200 – 400 more rpm. The exhaust tube adds stern lift while the over the hub lowers the stern offering more bow lift (probably not a benefit with all the weight in the back of the boat).

  6. Scott,

    I participate in a redfish series in Lousiana (live in AL) and “was” the fastest until one of my buds came in with a sterling rigged with a 250 SHO. He says he went to the BRAVO I XS and went on and on how much difference it made all around but especially on his top end.
    I am trying my best to get everything I can out of what I have….I currently have a prop now for hole shot and cruising and I am looking for advice for strictly top end.
    Here’s what I got:
    Lake & Bay 22 Backwater – Total weight Boat/Motor/Fuel/2 persons/gear – 3400lbs
    (The hull, for a bay boat, is considered high performance stepped hull)
    Mercury 300XS – 2009 – torquemaster 1.75:1
    Bob’s 10″ hydraulic jackplate
    Results with 25 pitch Fury (bought last year)
    RPM’s – 5900 – 71mph – 11% slip
    Air Temp – 85
    Water conditions – Light chop
    Results with 23 Tempest (came with boat and could use a little work so performance may be a little better than listed below if prop edges were cleaned up)
    RPM’s – 6100 – 65mph – 14% slip
    Air Temp – 85
    Water conditions – Slick
    So, with this information can you tell me with a Bravo I lab finish (or Bravo I XS) what pitch I should chose and what improvement on performance I might expect?
    I can be contacted via email provided for personal contact information – I would love to talk to you guys!


    1. Great set up, sorry I don’t have any numbers on a Lake & Bay 300XS running the Bravo I XS. I can give you some idea of what you might expect but it always comes down to running the props to get accurate numbers.
      If you’re hitting 5900 with a stock 25 Fury history with other applications tells us you can run the 26 Bravo I XS hitting the same WOT RPM. The Lab Bravo I being thinner compared to the XS offers 100 added RPM (pitch for pitch) bumping you up to 6000 RPM.
      It will come down to slip; if your slip stays at 11% you would expect an increase to 72-72.4 with the XS and possibly 72.5-73.4 with the Lab. Again, nothing beats running the props.

  7. Scott:

    I have a new 620 being delivered this week with a Vrod Pro 250. I have a DAH tuned Rev4 19″ for it already. On Merc’s site it (a specific test on a 620 with my exact motor) should turn 6300 and run 62MPH with a full tank of fuel and on person on board. Any thought on how the Bravo XS would run? I really like the hole shot numbers of the Bravo XS. Very much like your candid thought on this blog.

    1. Greg,
      Nice rig. The Bravo I XS is geared toward two stroke motors; the vent holes help the engines with bottom end torque for planing the boat. Your new Verado Pro 250 has a great deal of bottom end torque and will blow the prop out making it difficult to plan the boat. Once on plan the prop will work great. We are currently developing a version of the Bravo I for Verado applications. Expect to see some performance data this fall.

  8. Scott what kind of engine height does this prop like? I have played with engine heights, I noticed the Rev 4 doesn’t like engine height, the Tempest I was able to raise up one more hole vs the Rev, I seemed to bow lift with the Rev when i raised the engine.

    1. The four blade Revolution 4 has a long exhaust tube which adds a tremendous amount of stern lift. The stern lift can help when there is allot of weight in the back of the boat (kicker, batteries, live well). In your case, by increasing engine height too much causes the tip of the blades to do most of the work – the Rev 4 has a lot of cup at the blade tip.
      The three blade Tempest Plus on your boat will offer good bow lift at various engine heights. To much engine height, is not always good; you can loose bow lift, cavitation can occur during planing and in turns and top speed can drop.
      There are several ways to measure engine height; a simple way is measuring the distance from the bottom of the boat to the bottom of the cavitation plate. To do this, trim the motor so the cavitation plate is parallel to the bottom of the boat, next hold a straight edge to the bottom of the boat running to the gearcase, taking a tape-measure measure the distance from the straight edge to the bottom of the cavitation plate. For a 60 MPH boat, 3-3.5″ should offer the best performance.
      It’s good you’re trying various prop, engine heights dialing in your set up. I’m looking forward to seeing your results with the new 22″ pitch Bravo I XS.

  9. How does the Bravo XS compare to a Pro ET pro finish and Pro ET lab finish. The lab finished 28′ Pro ET is the fastest of the 2 on a 24′ Checkmate with a 300XS. Close to 80mph.

    1. Brent,
      Pro ET 4 blade: pitch for pitch, the Lab Finished gains 150 RPM over the Pro Finished which can lead to 1.5 to 2 MPH gain.
      Pro ET versus the Bravo I XS: for applications that can run the Pro ET, it will offer better top end numbers. The exhaust tube of the Bravo I XS in these applications can cause drag in addition stern lift lowering the top number. Not all boat/engine combinations run well with an over the hub style prop, the Bravo I XS or Lab Finished Bravo I will be a better choice.

  10. Scott, Got some impressive numbers this afternoon, back to back tests with my blueprinted Tempest 21. 1/2 tank of fuel, all my fishing gear(basically what I fish derbies with) I was by myself but I have found the second person doesn’t slow me down, because in the past I have hit 58 with my Tempest with 2 people.

    The cavitation plate is 4″ above the bottom of the boat.
    Bravo XS 22
    55d air temp 69d wtr temp
    It was pretty windy but back to back tests in like conditions gives me an apples to apples test.
    57mph @ 5580 rpm into the wind
    60mph @5750/5760 rpm with wind I did hit the rev limiter once.
    4 sec hole shot
    Actually had a bit chine walk at 60 mph pretty cool hadn’t seen this since I bought my first Tuffy 1890 in 06 without any load! Love that feeling!
    Less part throttle lean, great mid range acceleration.

    56 mph @5650 rpm into the wind
    58 mph @5759/5760 would tap the rev limiter occasionally

    More mid speed lean

    Great prop! Its a keeper I am going to put a video on my website also.

    1. Kirt, to answer your question, I want to clarify we are discussing the differences between stock and Lab Finished Bravo I props. The Pro Finish Bravo I XS, as featured in my August 17th post Walleye Prop article, is yet another variant of the popular Bravo I propeller.

      Mercury Racing Lab Finished Bravo I props have a ground satin finish (created by a highly skilled prop technician). Stock Bravo I’s feature a high polished finish (created by prep grinding and successively tumbling stones and other media against props mounted in machines). Lab Finished prop blades are thinner, with sharpened leading edges and smaller cups. Stock Bravo I blades are thicker, in comparison to the Lab Finished models. The blades have a blunter leading edge and larger cup area.

      In most applications, our Lab Finishing process results in a gain of 300 RPM over the same prop in stock form. A move from a stock 22″ pitch Bravo I to a 24″ pitch Lab Finished model can result with a 2-1/2 to 3 mph increase in overall top speed. The availability of our Lab Finished props expands the range of applications. For example, if a stock 22″ pitch Bravo I lowers an engine’s operating RPM too low, the Lab Finished variant may bring the engine back to within it’s recommended RPM range as well as improve top-end speed and overall performance. We offer the Lab Finished Bravo I with or without 1″ vent holes. Vent holes can improve hole shot in some applications. Stock Bravo I’s come without vent holes.

  11. Scott,

    I have purchased a bravo 1 xs 28P for waterski racing. I have been using a 25P fury with great effect but am chasing a couple of top end mph. I find I have to run the Fury quite deep to maintain bite and handling.

    Can you tell me if the bravo can run a bit higher then the fury? To date I have only done one test with the prop and its holeshot appeared fantatsic. Top speed still to be tested with skier etc.



    1. Good question, Tom. The 3-blade Fury prop has a 14” diameter, smaller than the 15-¼” diameter Bravo I XS. By design, the Fury should run deeper in the water. The addition of a fourth blade on the Bravo I XS enables it to run at elevated engine heights, while maintaining an efficient thrust (see my blog post on prop efficiency). The 28 Bravo I XS may be too high of pitch. it will most likely lower your engine RPM compared to the 25 Fury. However, raising your engine height will increase engine RPM. How much RPM depends on how well the prop stays hooked up. Good luck. Let us know how you do.

        1. Tom,
          The height increase depends on set-up and prop diameter. The Bravo I XS is a large diameter propeller. Typically, those running it raise the engine 1/2″ higher than the standard transom height. I’ve seen some run their Bravo I XS engines as high as 1″ above the standard height. It all depends on the application and what you want to get out of it. Hole shot – mid-range punch or top-end speed. A hydraulic transom plate enables the operator to experience the full capabilities of the Bravo I XS. Bottom line, you have to try and figure out what works best for your application.

  12. I am currently running a modified Mark Croxton Throphy plus 25 ( reduced to a 24 etc) with all holes plugged except for on medium hole and the plastic vent collar. I am running it on Tuffy 2060 dc with a 225 opti , ( it is not an xs) cmc hyd plate 15degree reverse transom wedge. @ 5600rpm i am getting 64.9 -65 mph ( NO Chine walk steady as arock) with 15-20 gallons of gas and all my fishing stuff 20 rods etc. 15 hp 4stk. kicker , minnkota 80lp three batteries . I have an old style Throphy large hub 23 that I tried it won’ t do 58 mph , will the Bravo Ixs get me anymore than what I have right now ?

    1. It will come down to slip; basically will the Bravo I XS hook up better than the modified Trophy? Any chance you will be in northern Wisconsin Oct 14-16 for the Tuffy Boats get together? I’ll be attending the event and will have a few Bravo I XS on hand to test.

  13. I am running a flats boat non pad bottom with a Pro XS 175 my prop is a 21″ Tempest plus pitched up 1″. I run 60.2mph at 6200 with a fishing load with 1 person 95+ degrees. Could I expect better performance with a Bravo1 xs maybe a 23″ my load various a lot 1-2 people full or empty livewells. Would it be more likely to be slower than the Tempest? I would think it would carry the load better.

    1. The Bravo I XS might be the way to go. It depends on how your boat performs under light and heavy loads. A 3-blade prop such as the Tempest can increase bow lift and, with some boats, enhance top-end speed. The Bravo I XS enhances stern lift as well as bow lift. This is most beneficial when running under load with the addition of a second person, fishing gear, full live wells and a full tank of fuel. Most 3 blade-props can’t carry the bow when weight is added, reducing top-end speed by 3-4 mph.

      To help understand what to expect when comparing your modified 22″ Tempest with the Bravo I XS, I would suggest you use our prop slip calculator. Type in 22″ for pitch, 1.87 for gear ratio, 6200 for RPM and 60.2 for MPH, click the slip button and you should get 13%. Knowing the slip of Tempest prop, you can now get an idea what to expect with the 23″ pitch Bravo I XS. Go back to the slip calculator, type in 23″ for pitch and 6100 for RPM, recalculate the MPH and you should get 61.9 MPH. Next type in 6200 for RPM and you get 62.9 MPH. Hard to tell where the RPM will fall compared to the modified Tempest, but this gives you a general idea of what you could expect.

      Consider your engine height when running the Bravo I XS. Could you raise it another hole? If you had a jack plate, I’d try 1/4″ at a time. If you can hit 6100 to 6200 RPM, without sacrificing low-end performance under a heavy load, consider going up to a 24″ pitch Bravo I XS. Each one inch change in pitch results with a 150 RPM change. The 24″ pitch Bravo I XS will reduce your engine speed by 150 RPM (6200 to 6050).

      Have fun.

      1. tested all 3 of my props this morning making back to back runs 50 degrees out windy with a normal fishing load half tank of fuel.

        21″ Tempest plus balanced with more cup added. 6200 to bumping limiter at 60.3 mph I expected this to be the fastest prop.

        23″ Tempest plus stock 5800 at 61.8 normally not as fast as the modified 21″ ??????

        23 Bravo 1 xs 6200 to bumping limiter at 60.8 mph The Bravo xs did everything better except wasn’t quite the fastest but could use some more pitch. Might have left a little on the table had to be conservative on motor height and trim because of the rev limiter. Much better handling in the sloppy conditions today. This will be my prop choice for the way I use the boat the other 2 are for sale as of now. Hope this is of some use to someone.

  14. Scott I am extremely pleased with the Bravo 1 XS on my Tuffy, I have had it for better part of month in all kinds of water conditions. Boat handles great and speeds are very consistent under all load conditions.

    Thanks for a great product!

  15. I am currently running a Yar-Craft 219 TFX with a 300 Verado Pro, boat has Pro Kicker, bowmount, 4 batteries, full of gear, fuel, and 3 200+ # guys i am running 60.5 Mph GPS. this is with a DAH worked rev 4 19P, 6350 rpm + or -, third hole

    This setup has a great holeshot and sticks in the water like glue, you cant blow the prop out

    I have a DAH worked tempest 21p that i haven’t ran, i afraid i will lose all kinds of bottom end and holeshot, i mean this thing comes out of the water like a rocket ship.

    I dont know how i can find a better setup ( still need to mess with motot height a little), maybe this bravo would have a bit more speed, can you tell me about the fs prop designed for verado’s

    Will i lose any stick, bottom end or holeshot?

    thank you
    Gale Johnson

    1. Hi Gale. It sounds like you have a great Rig. Scott will get back to you first thing Monday regarding your rig and the potential for using the Bravo I FS with your Verado Pro 300.

    2. Hi Gale. We’ve received great feedback from walleye anglers who have experienced performance enhancements since switching to the Bravo I XS prop for their two-stroke outboard rigs. I think four-stroke outboard owners will enjoy similar success with the Bravo I FS. By lifting the bow and stern, the Bravo I FS provides speeds of three-blade combined with the ride and handling characteristics of a four blade.

      The Bravo I FS and XS props are essentially the same. One-inch vent holes in the exhaust tube of the XS enables a two-stroke outboard to gain engine RPM and power quicker for an enhanced hole-shot and mid-range punch.

      I spoke to Dean at Yar-Craft regarding your boat. Dean said your boat typically comes with a 21” pitch Revolution 4. In some cases, the 21” Rev 4 might be a little too much prop. Since a 20” Rev 4 is not available, guys are resorting to a reworked 19” Rev 4.

      When considering the Bravo I FS, you will want to move up 1” of pitch. For example, if the boat comes with a 21” Rev 4, you will want to go with a 22” Bravo I FS. When comparing the two – the 22” Bravo I FS should enhance your engine RPM and overall performance. Dean said the Yar-Craft’s typically handle and ride better with a 4-blade, so I’m not sure the worked Tempest is the way to go.

      I think we’ll be hearing several success stories as the Bravo I FS gains exposure in the walleye market. This durable prop provides amazing hole shot, mid range punch and top-end speed with enhanced boat handling and fuel economy.

      The part number for the 22” pitch Bravo I FS is 8M0064450.

      Have fun on the water.


      1. Thank you very much for the response. You are right, the Rev 4 21 was a little to much for my boat. I had good speed but wasn’t up in the required rpm. Holeshot and midrange is much better with the DAH Rev 4 19p. After further inspection, I am in the fourth hole, not the third like I had posted. I might go ahead and try an Bravo I FS.

        Thank you again.

        Gale Johnson

        1. I’d like to see you try the 22” pitch Bravo I FS. It should produce the same full throttle engine RPM as your worked 19” pitch. It’s tough to match the performance and efficiency of a prop that turns the same maximum engine RPM with an additional three inches of pitch.

          1. I may have found a used 22P Bravo I XS. Could I just plug the holes or are there other differences in the four stroke model?

            I don’t have any plugs at all in the Rev 4 and it seems to work great.

            Thank you for all your help.

          2. Gale,

            Thanks for your discussions; it helps educate all of us. I’d like to see you pass on the Bravo I XS and invest in a new Bravo I FS. The large 1″ vent holes promote cavitation. Cavitation increases two stroke outboard RPM and power for an enhanced hole shot. The opposite would happen if used on a four stroke, cavitation here would cause blow-out during planing. Unfortunately, there isn’t a vent plug for the XS. I’ve tried all kinds of fittings and plugs with no luck, they all blew out. The Bravo I FS really shines for the four stroke in big water where you will appreciate the enhanced boat control while running the slop (or waves).


          3. I ordered a 22″ pitch Bravo I FS one today. I will report back. The slip calculator on your website says it could run 67-70 if all things were equal. It could run 67 if my Rev 4 is actually about 20p; 70 if it in fact is 19p.

          4. Awesome, Gale. Thanks for ordering the Bravo I FS.

            The slip information doesn’t seem to add up. If you’re hitting 60.5 MPH on GPS with a Verado 300, spinning the 1.85:1 gearcase at 6350 RPM, the slip for the worked 20″ Rev 4 comes in at 12%.

            I look forward to learning your results.


          5. Last night I hit 63 @ 6400 by myself with the DAH 19p Rev 4 – Verado Pro 300 with 4.8 case; 1.75:1 ratio.
            If I plug in 20P, 1.75:1, 6400 rpm, and 63 mpg it says 9% slip. If I use 19P and the same numbers, it says 4% slip.

            I don’t know if my prop has a different pitch. It does have added cup, I do know that. The speed was GPS.

            This is were it gets interesting. With 22p and 9% slip, and everything else equal – it says 69 mph. Plug in 22p and 4% slip equates to 73 mph.

            What kind of slip should I be looking for with a Rev 4, and with the Bravo I FS?

            Gale Johnson

          6. Gale,

            You’re posting some great numbers with your Yar-Craft/Verado. The pitch of a prop, for simplicity, is calculated by combining blade face measurements. Start at the leading edge of the blade through the middle, working out to the trailing edge – including the cup.

            Don’t expect to see 69 or 73 mph using your slip numbers. The actual slip of the propeller is affected by multiple factors; prop design, boat bottom design, equipment and passenger weight distribution, engine height and water flow/disturbances in front of the gearcase.

            Prop pitch can be read in different ways. Actual pitch may not be as stamped on a prop or label. When comparing the Revolution 4 to the Bravo I, the Rev 4 is taller in pitch – accounting for the low slip numbers. In the end, what really matters is performance. No matter what your load – you get the ultimate in planing performance, ride, fuel economy, rough water control and top-end speeds with the Bravo I FS.

            In comparison, the 3-blade Tempest Plus typically offers faster top-end speed, but a challenging ride. The Rev 4 offers a much better ride, but you sacrifice top-end speed. The Bravo I FS combines the best attributes of both.


  16. I am awaiting the delivery of my Skeeter WX1990 to Mr. Marine in Fond du Lac. It will be rigged with the 225 Pro XS and no kicker. Currently considering my prop options and it seems like the Bravo I XS might be the best fit.

    Any suggestions on pitch and mounting height for this set-up would be greatly appreciated.

    1. How exciting, Eric. Bet you can’t wait for your new boat to arrive. I’m sure Scott will be able to help you dial it in. Scott will contact you Monday.


    2. Eric, what a sweet set up. Thanks for running the Mercury 225 Pro XS. I contacted Dan at Mr. Marine. Dan said guys are currently using Tempest and Rev 4 props on the Skeeter WX1990 and WX2100 hulls. The Tempest produces bow lift and a 2 mph speed advantage over the Rev 4. While speed is greater, the ride suffers. The Rev 4 produces stern lift, for an improved ride, but with a speed penalty. We are thinking the Bravo I XS may be your best bet with improved ride and speed.

      Dan is ordering a 22” pitch Bravo I XS for testing on the WX2100. We’re thinking this will also be the right pitch for you. The part number is 48-831910L60. We’ll provide you with an update as soon as Dan gets it tested.

      Have fun on the water.


      1. Thanks for the follow-up Scott!

        Sounds like delivery is 2-3 weeks out, so I’ll be interested to see how the 22″ pitch Bravo I XS works out. It would be awesome to have the best of ride quality and speed.

      2. I’ve had the new boat out a couple times. The 22p Bravo I XS is giving me an excellent hole shot and the rough water ride is also good.

        Top end I’m hitting 53.5mph at ~5600rpm. Is that about what I should expect, or would raising the motor up a little help? Right now the cavitation plate is 2″ above the bottom of the boat.

          1. Thanks for running Mercury on your Skeeter. The recommended RPM range for your engine is 5500 to 6000. You’re getting a good hole shot with your current set-up. The Bravo I XS is a large diameter prop that, in many cases, provides better performance at higher transom heights compared to a 3 blade prop.

            Raising the engine height can enhance full throttle engine RPM for higher top-end speeds. The trick is to obtain the higher top speeds without sacrificing hole shot.

            If you have a jack plate, I recommend raising the motor in quarter inch increments until you reach the sweet spot (it’s a little more challenging to do this when you have a fixed transom due to the spacing of transom bracket mounting holes in one-inch increments). For reference, the distance from the bottom of the boat to the bottom of the gearcase cavitation plate is 3″ to 3.5″ on a 60 MPH boat.

            Raising the engine height of the engine using the larger diameter Bravo I XS prop could result in a gain of 100 to 150 RPM engine speed with a top-end speed of 54.5 to 55 MPH.

            Have fun


      3. Scott any reviews on the WX 2100 with the 22″ Pitch Bravo FS? I run a 300 offshore and I am wanting to purchase a Bravo. Just not sure if I should go 22″ or 23″. I currently have a manual jack plat

        1. Mike,
          Local Mercury dealer Mr. Marine is using the Bravo I XS and FS on the Skeeter WX 2100. What prop and pitch are you currently running? What is your performance at WOT? The Bravo I FS is designed to enable you to move up in one inch pitch increments. If you’re running a 19″ pitch Tempest, then you could move to the 20″ Bravo I FS. We also have a 21″ Bravo I FS. Part numbers for the 20″ is 8M0090451 and 21″ is 8M0090455.

  17. I have a 197 Lund GL with a 225 Pro XS on it. I am looking for a prop. I’m wondering what you guys think I need. I’m looking for for a decent hole shot and top end. I also have a 4.5 set back jack plate. I fish tournaments up in Alberta. Some ideas would be great. Thanks.

    1. Troy,

      Thanks for reading our blog and contacting me regarding the best prop for your application. I’d like to point you toward the Bravo I XS. However, before I can do that, it would be helpful if you could let me know the model, size and pitch of Mercury prop you’re running as well as your full throttle RPM and top GPS speed. Please also let me know what you like and don’t like about your current prop.

      I look forward to helping you refine your ride.


  18. I am currently running a similar set up as Gale Johnson’s. I run a 2012 Yar-Craft 219 TFX but with a 250 Pro XS (XL). I believe the engine is mounted 4th hole (one from the top). My boat is also rigged with a Pro Kicker, bow mount trolling motor, four batteries, loaded with gear, fuel, and three grown men. I am running 57-58 MPH GPS. This is with a 22P Tempest Plus. I also have a a 21P Rev 4. I get 55-57 with it, but it has too much stern lift. This causes the prop to break loose in rough water.

    My boat was set up by Dean and the guys at Yar-Craft in Wausau. They recommended the two props I currently use. Both setups have a great hole shot. The Tempest sticks in the water better, but I can’t trim it up a ton without getting porpoising. The Rev 4 blows out a lot easier.

    I’m looking to get a little better performance, both at top-end and in rough water. I’m wondering if I should consider picking up a 22P Bravo 1 XS and try it? I played around with a 21P Tempest but that slips too much on hole shot and mid range.

    Any thoughts?

    1. Hi Robert,

      Thank you for your Bravo I XS inquiry. The Bravo I XS should be the ticket for all-around performance with light or heavy loads and in calm or rough water. The Bravo I XS and FS propellers enable you to move up in 1″ of pitch while maintaining your current RPM. For example, you may be able to run a 23” Bravo I XS at the same full-throttle RPM as your 22” Tempest along with the added top-end speed and enhanced handling characteristics that come with the Bravo I XS design. To help answer that question, please send me your full throttle GPS speed and RPM for the Tempest and Rev 4.


      1. Awesome! I will get some numbers with the Tempest tonight while I am guiding up on Green Bay. I can switch out to my Rev 4 and try it on Friday.

        Thanks Scott. I appreciate the assistance.

        Capt. Bob

        1. Robert, Thanks for gathering the test data this weekend. If you would like, I could come to the Bay sometime next week to help you test your boat with 22″ and 23″ Bravo I XS props. I’ll supply the props. Let me know if you are interested and if so, what dates and times work best for you.


          1. Hey Scott, I have been swamped… I just saw your posting about coming up here to test the props. That would be great I am for sure game. Not sure if you have other plans at this point considering it is already Friday the 13th. Otherwise maybe some evening this next week. Let me know and we can make some arrangements. I was planning on heading to The Wolf River Sat to chase some Walleye so if that would be a more convenient spot to try to meet and try some props we can see about that.

            I was out last Thursday Friday and Sat. night but was not able to get any good runs in due to conditions.

            I did however get a good run in last night.

            2 people full tank of fuel and gear, basically what I would run Tournament rigged. I had the Tempest on and trimmed up a little had her at 57-58 mph on the GPS and 5480 RPM.

            I am hoping to run the Rev 4 this weekend.

          2. Hi Robert,
            We’ll have to pick it up in May; my calendar is booked for the next two weeks. Shoot me the numbers of the Rev 4 when you have time. Good luck fishing and I’ll contact you in May when hopefully our schedules will allow us to test the Bravo I XS.

  19. Scott, I’ve read your entire page with much interest! I have a 21′ Cougar with a stock 300XS. The boat came with two props, one a Merc 15X30 3-blade cleaver. Great top-end at 104-105. The other prop was a Bravo I XS, 15.25X24. It was way too small, so I sold it. I am wondering if I should jump to the 28 or just go up to the 26. The 24 ran about 85 mph,so I’m leaving a bunch on the table compared to the cleaver. The only problem with the cleaver is it won’t get on plane with a lot of weight in the boat. However, once it goes over it’s gone! The other thought was if it would be better to go with a four blade cleaver for a better hole shot?

    Thanks for any info. I haven’t run the boat this year yet, and I can’t recall rpms at all. Sorry.

    1. Nice set up, Honk. I like your idea of having two props, the Mercury Cleaver for top-speed and Mercury Bravo I XS as an all-around work horse. The Cleaver was first developed for racing and thus it is designed for top-speed on lighter hulls. A Bravo I XS, with the right pitch, could get you close for your desired top speed but you would still have the hole shot problem when your boat is loaded with passengers and gear.

      In the right pitch the Bravo I XS will provide the hole shot you’re looking for along with excellent mid range punch. So what pitch to go with? The previous owner may have used the 24” pitch Bravo I XS for water sports such as tubing, wake boarding or skiing. Moving to a 26” pitch will drop your engine speed by 300 RPM. You will lose another 300 RPM if you were to move up to a 28” pitch Bravo I XS. Your numbers tell me you’re probably bumping the rev-limiter with the 30” Cleaver. The Bravo I XS is designed so you can move up 1” of pitch. A 31” pitch Bravo I XS would enable the engine to turn the full throttle RPM you get with your Cleaver. Since you’re looking for a load carrying prop, I recommend you step down 2” in pitch and try the 29” pitch Bravo I XS. You will gain 300 RPM over that of the 30” Cleaver, so you will need to watch the rev-limit on light loads. And now, you won’t need to worry about heavy loads.


  20. Scott,

    I ran my 21P Rev 4 Saturday. My boat was tournament rigged with full fuel and 2 people, 56Mph @ 5400 RPM. The one thing is I was on the Wolf River and going up river. Although the current there is super slow right now.

    It has been a while since I had that prop on the boat and I did notice my hole shot was not great. Very sluggish compared to my Tempest. I could for sure get the rear of the boat to almost chine walk a bit. I think the Rev 4 is lifting the rear of the boat more than the Tempest.

    Let me know when you think you may have time to hook up and play with some props.

    Thanks again.

    1. Hi Robert, how does a week night after 6 PM work for you? I could come up May 30 or 31 or June 6 or 7, weather permitting.

        1. Bob,
          I’ll meet you June 7 at 6 PM by the Green Bay launch bringing the Bravo I XS 22″ and 23″ pitch props. Can you bring the wrench and block to change the props? Looking forward to visiting and seeing what you think of the Bravo I XS.

          1. Scott,

            Wish I could be there to test the Bravo 1 XS. I talked to you on the phone about my 2002 Triton 205 DC, 225 VMax & T8 kicker. The current prop is a 23 pitch High 5 with a manualjack plate and high mounted engine.

            This prop doesn’t provide much bow lift. It seem that I have excessive prop slip at cruise speed. Recommended engine operating rang 4500-5500 with red line at 6100 rpm. At 4000 rpm gps speed of 38 mph, 4200 rpm 40 mph and 5450 rpm 56.7 mph all at light chop on Pewaukee lake.

            Asper our conversation, I talked to Jimmy at Merten, but he didn’t have a 22 or 23 pitch Bravo 1 XS for testing. As I am running out of time, I bought a 21 pitch Rev 4.

            I really wish I could of tried a Bravo 1 XS.

            PS: can I swap, with you or someone at Merc, the new Mercury Hub kit that came with the prop for a hub kit for my application.



          2. Hi Bob,

            It would have been great for you to test the Bravo I XS. Merten Marine has one of the largest selections of props to test and they are good about you bringing your boat to run at their facility.

            We ran the 22″ pitch Bravo I XS last night on Bob Claus’s 2012 Yar-Craft 219 TFX with 250 Pro XS power. Bob and I are amazed how well it hooked up; from hole shot to wide open throttle. The prop kept the boat on plane through sharp turns (slow and fast speeds).You could feel it lift the entire boat at speed. Most 3-blade props provide bow lift; most 4-blades lift the stern. The Bravo I XS does both. It was an amazing feeling. The lake was flat calm – not ideal for testing, best if we had chop. Even so, we achieved similar RPM and top-end speeds as the 22″ Tempest. Bob kept the prop so we can get some rough water performance data. Stay tuned…


          3. Well even though the fishing part of my scouting run last night was a bust, I did get the boat in some choppy water on Lake MI. Solid 2′ wave’s with an occasional 3′.

            This prop BITES, and I mean that in the good sense. 🙂 I literally had to throttle back a bit as she wanted to rocket up and off the waves. We did not do any fancy maneuvering but tacking into waves, straight into them and going with them. The Bravo 1 XS really likes to dig in and push. I thought the boat had a better ride than it did with my Tempest.

            Stay tuned for some more runs as it looks to be pretty windy the next 5 days. I should get some time on Bag and Green Bay.


          4. Bob,

            Thanks for continuing to test the 22″ pitch Bravo I XS. You can’t beat real world running experience. The flat water we had for our test run Thursday wasn’t ideal for showing how the propeller stays hooked up in rough water but it did give us impressive hole shots and your Yar-Craft 219 had a new feel resulting from the XS lifting both the stern and bow out of the water. I would expect you’ll see enhanced hull efficiency offering increased fuel economy. The Bravo I XS, unlike your other props, stayed locked up through tight turns at both fast and slow speeds and stayed on plane at slower speeds. Top speed and RPM was comparable to your 22″ pitch 3-blade Tempest.

            I’m Looking forward to hearing about your runs (and fishing success stories) on Lake Winnebago and the bay of Green Bay.

            If you get a chance, we would be interested in a back-to-back test comparing wide open throttle RPM and speed between the 22″ pitch Tempest and 22″ pitch Bravo I XS.

            Thanks again,


  21. Hi Scott,

    I’m currently running 53 MPH @ 6000 RPM with a 19P Tempest on a Ranger Reata 1850RS with a 175HP ProXS. I was wondering if i will be able to turn the 22P Bravo XS and if not should i consider the Lab Finish Bravo or just have the Tempest Lab Finished

    1. Nice set up, Cory. 53 mph is a good number. I think you can squeak some more top-end speed out of your rig, depending on how much you want to spend. The 19″ pitch Tempest is probably your best prop for all around fishing and water sports. The 22″ pitch Bravo I XS will drop your engine speed 300 RPM to 5700 RPM (still within the recommended operating range of 5500 – 6000 RPM). It will also increase your top-end speed by 1.5 to 2 mph. The larger diameter Bravo will affect hole shot acceleration and thus may not be the best for water sports. The other two props you mentioned have the potential for even higher speed numbers, but at a price. Hopefully you can get your hand on a XS and try it.


      1. Thanks for the reply Scott. I have a Bravo 1 FS on the way to get the best out of this rig and I’m looking forward to posting the numbers. I will probably have the Tempest worked on during our winter season while the boat is in storage as a back up and water sports as you mentioned.

        Best Regards,


  22. Hello Scott

    My boat is a 1999 620 dvs ranger, And have always had a thing for getting the most preformance i can. I have put a new 250 proxs *6 inch set back hyd jack plate . i run a 21 pitch tempest it runs 5850 , 58 to 59 miles 2 guys tournament load . the problem i have the motor does have a dead spot i call it between idel and 2200 rpm when i stab the throttle its slow to rev talk to dealers had them check coils and so on. they says it prop . somtimes when you stab it it wont even take off it wont rev past 1500. kinda goes into a limp mode . Anyway i have pulled the plugs out of the tempest still not like it should be. This motor seems to make great power at the top end and no torque on the bottom. Will the Bravo xs help and which pitch do you recommend. Another question i have is the Bravo 1 xs same as the old Bravo 1 with holes , thats what the dealer is telling me . Sorry one more question what is the rev limiter set on my 250 i think i am hitting it once and awhile, around the 5900.


    1. Hi Trent,

      Enhanced performance is what Mercury Racing is all about! Yes, we make racing propellers; but we are really known for performance props like the Bravo I XS. This prop will give you the performance you’re looking for. The large 1″ vent holes will allow your engine to breathe. The enhanced RPM will produce the jaw dropping hole shots you are hoping for. The XS lifts both the bow and the stern, giving your boat a whole new feel. The 22″ pitch Bravo I XS stays hooked up in tight turns and keeps the boat on plane at slower speeds. All this while matching the top-end speeds you are seeing with the Tempest. The Bravo I and Bravo I XS begin life from the same casting. The similarity stops there. Mercury Racing prop technicians work their magic for enhanced (”XS”) Bravo performance. They work the leading edge, machine in 1″ vent holes, reduce the flare of the exhaust tube (barrel), fine tune and match the cup on each blade and precision zero balance each propeller. If you’re hitting the rev limiter with the 21″ Tempest, consider moving up to the 23″ pitch Bravo I XS. You’ll get all the benefits of the 22″ plus increased speed.

      Good fishing,


  23. I am running a 2009 Skeeter WX1880 with a 200 HPDI, I tried to find one with an Opti but couldn’t, sorry. Problem is, in stock form the boat would put every 21 on the rev limiter, 5800 rpm and 55 mph plus or minus 1. Props tried were Tempest, HR Titan 4, and Yamaha Pro Series. I tried a couple 23 pitch props and couldn’t get them to spool any rpm’s so I installed a 5.5″ CMC pl-65 jackplate in hopes of running 23 pitch props. After some set-up time I got the boat to start turning 23’s alone with a full load but the boat suffers slightly with an extra person in it and a full load. I know Mercurys reputation in prop building and need a good primary prop and hope to turn the 23 Pro Series into my spare. Any help will be greatly appreciated as it is very hard to get a 23 up here in ND to try (everyone runs 21s). I had time to set the jackplate up and performance is as follows;

    Yamaha Pro Series 23
    Alone and fully loaded – 58.5 to 59.5 and 5650 to 5700 rpm
    2, 200 lbers and fully loaded – 54.8 to 56.5 and 5350 to 5400 rpm

    Tempest + 23
    Alone and fully loaded – 55.5 to 56.5 and 5400 rpm
    2, 200 lbers and fully loaded – 53.5 to 54 and 5200 rpm

    High Five 23
    Didnt try it alone
    2, 200 lbers and fully loaded – 53.5 to 54 and 5800 rpm

    Ballistic 23
    Alone 5800 rpm and 51 mph – didnt see a need for further testing-

    Any help would be greatly appreciated,

    1. Hi Neil,

      The information you’ve provided is helpful in gaining an understanding of how the props are working with light and heavy loads.

      After calculating prop slip, I’m thinking the 23″ pitch Bravo I XS is going to be the answer. The Bravo I XS is designed to allow one inch increase of pitch compared to the Tempest. Looks like you could use a little more RPM, thus I’m recommending the 23″ pitch.

      The 23″ Bravo I XS will increase your engine speed by 150 RPM. Your hole shots will improve and you can expect consistent 55 MPH top-end speeds under heavy loads.

      Have fun,

      1. Thanks for the information, and the good tech support Scott. Ordered a 23″ Bravo 1 XS today from Jacos Marine. Should be here the first week in July. I will be sure to post the performance of the prop after I set the jackplate for the best top end and holeshot versus the 23″ Pro Series.

          1. I ran the 23 P Bravo XS this weekend. I adjusted the jackplate until I had positive trim and speed started to decrease, trimmed the engine in until the roost was about the same height as the top of the cowl on the engine and speed was the fastest. Results were:

            Alone full fuel and gear, 5675 rpm and 56 mph 15.5% slip
            Two adults full fuel and gear, 5400 rpm and 53 mph 15.5% slip

            The prop had a 5 to 6 second hole shot and carried bow very high, on my boat the prop acted like it was using all its energy trying to lift the bow and not really propelling the boat forward (on my boat). I contacted Scott and Mercury Racing is going to take some of the cup out of the tips to get the bow to settle down a bit and try to gain 100 to 150 rpm back. I will update as soon as I get the prop sent to them and get it back.

            As a side note, a friend tried it on his 2005 Champion with a 225 Opti. It ran 60 mph at 5700 rpm with full fuel and 3 adults, and 61.2 mph and 5750 alone. It is the fastest prop he has ever run on his boat.

          2. Neil,

            Can you help us out by providing details regarding the make and model of your boat? It would be helpful to know the number of batteries you have on board as well. Please also share your 3-blade prop performance results.


          3. Boat is 2009 Skeeter WX1880 with a 200 Yamaha HPDI, 1.86:1 lower unit. Has a T8 kicker on the port side transom and an 80lb Terrova on the bow. I have one group 24 starting battery in the back starboardcenter compartment next to the oil tank, and two group 27 deep cycles in the bow just ahead of the full windshield. I load the front of the boat fairly light and have two good sized tackle boxbags that I set as far back in the boat as I can. As for the 21 pitch props I was very close to running them on the limiter before adding the jack-plate. I added the jack-plate so I could go up in pitch to get off the limiter. I have had a jack-plate for the last two years, but if memory serves before the jack-plate the numbers were as follows:

            21 Yamaha Pro Series
            2-adults full fuel and gear: 54 to 55 mph and 5775 rpm
            Prop had a nice ride at speed and an awesome hole-shot

            21 Tempest +
            2-adults full fuel and gear: 55 to 56 mph and 5750 rpm
            Prop rode awesome at speed and a very, very good hole-shot

            21 Solas HR Titan 4
            2-adults full fuel and gear: 53 to 55 mph and 5750 rpm
            Prop rode nice at mid-range, respectable hole-shot, with a lot of transom lift

            I don’t remember the others I tried before the jack-plate, sorry! I don’t want to feed someone the wrong performance information due to my lack of remembering. I really hope this information helps some one out there with their prop issues.

  24. Scott. How does a Bravo 1 XS compare to a stock Bravo 1 in terms of bow lift and rpm? I curranty run a 28 stock bravo one on a 24 checkmate. 76 mph at 5900 running a 300xs. (shaft 1.5″ below pad on a Torquemaster) I would like some more rpm but retain the top speed (and bow lift characteristics). How do these two props compare pitch for pitch so i can make a decision on which pitch will suit me most?


    1. Joe,
      You might want to stick with the 28″ pitch Bravo I. It seems to be providing good performance. If you get a chance, try the 29″ pitch Bravo I XS. The Bravo I XS is going to offer you 100 to 150 more RPM. The leading edge of the blades on a stock Bravo I are blunt for enhanced durability. Full blade cup enhances bow lift while the full-length exhaust tube creates stern lift. The Bravo I XS is zero balanced, leading edges are wedged for improved water entry, cup heights are reduced to increase RPM and the exhaust tube is shortened to minimize stern lift. If the 29″ Bravo I XS works on you Checkmate, expect another 1 to 1.5 MPH on the top.

      Have fun.

  25. Well the prop search is finally over. I run an ’08 Triton 215 with an ’08 250 Pro XS and a 9.9 Mercury kicker. Also have 2 batteries in the back, no jack plate. Motor is mounted in the second to last highest mounting position (4th hole from the top). I have tried numerous different props in the last 2 seasons trying to find the perfect prop. Elevation is my biggest dilemma in finding something I can turn up to 5900 RPM, elevation is normally 3400 to 3900 ft.

    – Tempest Plus 21 pitch, 5900 rpm, 57.5 mph. RIDE NOT GOOD! Also porpoised.
    – Rev 4 21 pitch could barely turn 5700 rpm, 54 mph. Gripped good but ride not good. Hole shot is horrible. Porpoised.
    – Rev 4 19 pitch could get to 5950 rpm, 55 mph. Good grip but lots of bow lift when the live well is full. Decent hole shot. Porpoised bad unless full trimmed down.
    – HighFive 21 pitch, 6000 rpm, 55 mph. Decent grip in rough seas. Rode like a Cadillac but would not hold the bow up and would porpoise some. Fast Hole shot. The HighFive’s small blades WOULD NOT BACK UP… PERIOD!
    – Powertech ofs 4 19 pitch. rode good, couldn’t get to more than 5750rpm, 53 mph.
    – Powertech ofs 4 18 pitch, TOTALLY different ride characteristics than the 19. hit rev limiter. I think the consistency in these props is bad from one to another.

    NOW, tried the Bravo I XS 22 pitch, 5850 -5900 rpm, 58 mph- 60 mph. Great hole shot. Fantastic ride! I can maneuver around the dock and backup. Holds the boat up well, doesn’t matter how much weight is in the boat (added one person and filled the 48 gallon live well in the back). Top speed dropped only 1 mph. Absolutely eliminated the porpoise problem this boat has had since I bought it. Handles in rough seas well and is very drivable. This is the prop for my setup, no doubt. Thanks again to Scott for his insight, he told me if I could turn it at this elevation I would like it and he was right on the money.

    1. Wow! that is awesome, Darren. I’m glad the XS worked so well on your boat. Thanks for your efforts and sharing the performance results. Triton owners will appreciate reading your thorough test data in their quest to find the right prop. At Mercury Racing our goal was to offer the Walleye market a durable performance prop at a decent price that’s ready to go right out of the box. It looks like we hit a home run with the Bravo I XS.

      All the best,


    2. Darren are you still happy with the BravoIXS prop, I have same 2008 Triton as you do. My Tempest prop give me some of the same problems you mentioned also some chine walk at high speeds.

  26. Hi gents, it has been a while since I have had an opportunity to post any results, I have been swamped with fishing, fishing, and more fishing. 🙂 Unfortunately with all that fishing and guiding it means I have not been able to run my other two props in comparison one after the other behind the Bravo I XS. I fully intended on doing so and may actually get a chance this week since my booking schedule is light.

    I will say this…. I am not sure I will ever run a different prop. The Bravo I XS I have locked on my 250 Pro XS is by far the best all-around performance I have seen on my boat and motor set up yet. My 219 Yar-Craft is a heavy rig and this Bravo I XS prop makes her stick to the water like glue. Yes I may get a slight bit more speed (one Mph) out of my 21″ Tempest but I have been in some snotty water this summer and since hooking up the Bravo, I have never once blown out the prop! My top end speed with 2 people, 3 people, or 4 people, in the rig seems to be 56-58 steady, the prop assists that big Merc in hooking up at all speeds ranges and maintaining a solid bite at any speed and condition on the water.

    Boat control is outstanding and I love the overall feel of the boat on plane in calm or choppy water.

    I seriously can’t see myself ever going back to a stock Tempest for a big Walleye boat.

    Scott and the crew at Mercury Racing have a gem here!

    Stay tuned more data to come…..

    1. Hi Robert,

      Glad to hear you’re having a busy summer guiding. Appreciate the performance information. Your decision to upgrade to the Bravo I XS is a great testimonial, knowing your livelihood comes from your time on the water.

  27. Hi Scott,

    First of all, thanks so much for sharing you expertise regarding props and boat set up. I’m currently running an 09 Trition 215, 300 Verado and a 5″ BMS Extreme hydraulic jack plate, 9.9 Prokicker and 5 batts..
    I run 3 props (all prepped for high x dim. by DAH), a 23p Turbo TPX for a very light load high speed (71.5 mph). It has a terrible holeshot but got the # I was looking for and I will most likely never run this prop again.
    I also run a 21p Rev4 which turns 6250 rpm, 1652′ elevation, 68 degree wt., medium load 64.6
    And a 19p Rev4, 6300 rpm, 78 degree wt, heavy load, 60.8 mph.

    I was happy with the overall performance of the 21p Rev4, however, the first time a ran with 4 guys, 80 degree wt, and a full livewell (in the back) I had a terrible time trying to get the boat to plane out. I discussed this with John at DAH and we both agreed that a 19p Rev4 should help. The 19 certainly helped out BUT, I have a constant battle with porpoising running with this scenario. The Triton 215 was originally designed with a lighter 250 Pro XS in mind. The beam is 94″ compared to 99.5″ on the newer Ranger 621’s. After some considerable prodding, Triton raised the HP limit to 300 on the 08 and up hulls.

    Effectively I’m running 138# more motor weight, 88# more jack plate, and 65# more for the power steering battery.

    With this information in mind, what are your thoughts in regards to the porpoising issue and a Bravo 1 FS 22p? I’ve even thought of going with trim tabs for that heavy load situation (25%) of the time.

    I guess I want my cake and eat it too!

    1. Hi Phil,

      Thanks for your question and information regarding your set up. You may be able to “have your cake and eat it too” with the 22″ pitch Bravo I FS. Dependant upon the cup work the prop shop did on your Rev 4s, you could see a slight RPM gain when running the 22” Bravo I FS. I expect you would see similar performance with the boats featured in the blog. Let me know when you get your Bravo I FS. And please don’t send it out to a prop shop for rework! The prop is dialed in from the start: zero balanced, wedged leading edge, matching cup heights and modified exhaust tube – all for maximized efficiency and performance.



  28. Scott, My 250 Pro XS is mounted on the second hole from the top, so pretty low. What are your thoughts on how this Bravo I XS prop will perform if I were to bring the motor up one hole or even 2? I am thinking about adding a jack plate in the off season. Probably a 6″ manual for added tweaking.

    1. Hi Robert,

      Try moving up one to the third hole. You might see a gain in RPM and a slight increase in speed. Moving up to the fourth hole could be the point where the gearcase no longer lifts the bow and the prop begins to slip. The Bravo I XS runs better than other props at elevated transom heights due to its large diameter, 4-blade design. A jack plate would be useful in obtaining the ultimate engine height. For example, with your engine height at the third hole setting, you may find continued efficiencies and performance with the engine raised up another ¼” to ½”. Anything beyond that, say the fourth hole, may prove to be too much. With the jack plate, you have the versatility to adjust transom heights for various props, loads and conditions.

      All the best,


  29. Have a new Ranger 620 delivering next week. You may not want to hear but it is coming with a Evinrude E-tec 250 HO. How would the Bravo I XS prop work on this rig. It will of course have the magnum gear case. Thanks Perry

    1. Hi Perry,

      The Bravo I XS works awesome with your set up. Mercury and Evinrude dealer Pamps Outboard, in Green Bay Wisconsin, recommends running the Bravo I XS with a Ranger/E-Tec. They helped us test the prototypes during the development process. The 25″ Bravo I XS, part number 48-831912L80, is the correct pitch for your 620 – especially with a heavy load. The 24″ pitch Bravo I XS, 48-831912L60, works best on the 621 with a 250.
      Good fishing,


      1. Thanks for the comments, my boat was ordered from Pamps and we are going to put a 25 pitch on and see how it works. Jody with Pamps is running that on his boat, same setup and says we should start there. He did mention that he can hit the rev limiter and could turn a 26 easily. Thanks again.

        1. Hi Perry,
          Awesome, good idea starting with the 25″ Bravo I XS. Selecting the right pitch depends on the conditions you’ll be running and the amount of added weight in the boat. For example when fishing Erie, I’d prefer the 25″ for a quick throttle response. If…no when the water kicks up – the more boat control the better for running those big waves.
          All the best,

          1. The boat came in yesterday. Should be taking delivery on Thursday I hope. Jody ordered the prop on Saturday. Boy, I really want to take delivery with this prop on. It came from Ranger with ofcourse a BRP Rebel prop. Can this prop be rushed? What will I see for speed with this setup? Thanks Scott

          2. Hi Perry,

            Congratulations on your new 620 Ranger. I wish I could tell you we have a prop ready. Unfortunately, we are two weeks out for delivery. I’ll see what I can do to get yours out as soon as I can. It’s been an awesome year for the Bravo I XS and FS prop lines.


  30. Hi Scott;
    Had a chance to test the Bravo I XS 25P, cannot say enough good about it. Does it all, holeshot, mid-range and top end besides. 61MPH and can hold boat on plane at 20MPH. Thinking I have a slight vibration however, need to put old prop back on and compare. I would surely think these props are carefully balanced.

    1. Hi Perry,

      Thanks for the good news. That’s some awesome performance! The props are carefully tuned and balanced; I’ll give you a call to arrange for me to inspect the propeller.


  31. Looks like it has been pretty Quiet out here on the Blog…… Everyone must have their boats stored for the winter! LOL! I hope all of you have a very Merry Christmas and a great New Year!

    1. Bob, we have some activity. Recently completed the Musky Hunter blog featuring the Bravo I FS and Jim Saric. Check it out to see Mercury’s Senior Product manger Steve Miller support Mercury Racing promoting the FS. Recognize the area? This past September Steve and Jim tried their luck on the Bay of Green Bay. Winding but they made it out landing one 50″ and having several follow ups. Thanks for the greetings and back at you along with all the anglers, Merry Christmas and Happy New year.

  32. Hi Scott,
    I have an ’05 Triton 177/ ’06 150 Opti. In researching, I have not found much info on propping mid size walleye boats. I currently run a 19p Tempest Plus. I’m wondering if a 4-blade would perform better. My set-up includes a Pro Kicker, rear live well, starting battery, etc which makes it a little stern heavy. The boat has a porpoise problem which I hope to fix with a jack plate and right prop. Is a Rev 4 the right choice? I also considered a High Five/no jack plate. I really like the reviews of the Bravo XS but not sure if my 150 will swing the 22p.

    Seems most of the reviews are aimed toward 225-300hp OB’s. Any help appreciated.

    1. Steve,

      Thanks for the prop question. You are correct. There is a lack of propeller discussion for mid size boats. The small tube Trophy works okay but if you run in rough, big water it’s not the prop to use. The HighFive will drop your speed 3 – 5 mph and its reverse capabilities lack. The Rev 4 is a good prop. However, to achieve similar RPM as what you’re getting with the 19″ pitch Tempest, you’ll have to drop down to a 17″ Rev 4. You’ll again see your speed drop 2 to 3 mph. There is one more 4 blade Mercury propeller that you may want to consider. It is called Vensura and it’s on my list for 2013 to see if we can fine tune for mid size walleye/bass/flats boats. The Vensura at one time was called the large tube Trophy. Back in the early bass boat days it kind of got lost because the small tube Trophy out performed the large tube. I think the Vensura has potential and with some modifications it may prove to be the prop of choice. Keep an eye out for a future post regarding our work with the new Vensura prop.


      1. Hi Scott,
        I took your advice and purchased a 19p Vensura and am very happy with the outcome. Ended up with 5350rpm’s @ 47.2mph gps. Come out to like 9% slip, depending on which online calculator I use. This prop performed very well, holeshot was good and had great bow lift. Would you recommend reworking to gain a few rpms?? If so what would I get done to it.

        1. I want to also add that my motor is mounted second hole. Would raising the motor gain me the rpms needed without the prop rework. Am hesitant on putting on a jack plate as I have read shorter boats (mine being 17′ 3″) do not benefit from them as much. What are your thoughts on this.

          1. Steven,
            The Vensura can handle increased engine height. It depends on the boat, but typically the maximum height is the third hole from the top. I’ve seen impressive results with the prop run on larger walleye rigs powered by V-6 ProXS or Verado Pro motors. I haven’t heard or seen how well they work on the smaller rigs. My thought is not so much. If you raise your engine, (make sure you have good water pressure) let us know your results for rpm, hole shot and top speed.

        2. Hi Steven,
          Thanks for the information. If you’re interested, I would like to see if Mercury Racing can get a little more performance out of your prop. It would support our development and help us understand what we can do with the Vensura prop. I’ll take care of the modifications to the prop along with freight back to you. Can you send the prop to us and be without it for a couple of weeks?

  33. I have a nitro 189 sport 2011 with 150 pro xs , the prop is a laser II 23 pitch , wot 5800 rpm , 58-60 mph ,, no jack plate ,, I try a mirage 23 pitch and i have greatest result , same rpm but 62-63 mph ,,, i want put a bravo 1 xs maybe with manuel jack plate ,, it is a great choice ?and what pitch can i put?? scuse my english , i speak french ,,thanks Joe

    1. Joel,
      Merci. The Bravo I XS should be a great prop for your Nitro. Great planing and good mid-range pulling power for the water sports. Top speed should be close to the Mirage. The jack plate might help you fine tune the engine height for even greater performance. Plan on increasing to the 24″ pitch XS if you want to equal the same rpm as the 23″ pitch Mirage. If you are interested in installing a jack plate, first run the Mirage before you purchase the Bravo I XS. You may find you’ll need to increase to a 25″ pitch.
      Profitez de votre bateau,

  34. Scott I am running a year 2000 Bass Cat Jaguar. W/ Mercury 250 Pro X B ( EFI ) I am wanting to put a new Bravo 1 X S 27 or 28 P. Prop on this rig. I have a 8″ Bobs Hyd. Jack plate. Have been running a 26 Fury & 27 Tempest Plus. Both props are slow out of he hole with turney loads. Top end with the Tempest 75. RPM 6000. The new Bravo 1 X S I will send to have 4 extra vent holes. Any help you give me is appreciated.

    1. Philip,
      The Fury runs tall in pitch while the Bravo I XS is light in pitch. Using the 26 inch Fury as your bench mark, a 28 inch Bravo I XS should hit similar rpm. The Fury likes to run deeper in the water compared to the Bravo I XS. Test by raising the engine (keeping good water pressure) to an appropriate height for your set up. If you still need added venting for that stout 250 Pro XB (what a great motor), then get them punched in to help planing.

  35. Hi Scott. I recently picked up a triton SF-21 with a yamaha 3.1L. I generally run Merc props on my boats regardless of the engine brand, so i’m very interested in the Bravo I XS. I just tried a 22P enertia on the boat, and it ran pretty well unloaded, 60 mph (GPS) at 5800 RPM. When loaded with people I lost about 5 mph and seemed to be lacking lift… How do you think the big 4 blade Bravo XS would do on my boat? I’m not overly concered with holeshot as I will keep a prop (maybe the enertia) purely for the rare occasion we do watersports. Thanks for your help!

    David Patten

    1. David,
      Well, we are glad you’re running Mercury propellers. Thanks for considering the Bravo I XS. The prop is a work horse and will keep lifting the heavy loads. It may not be as fast as some 3 blades with light loads, but how often do we have a light load. Hole shot and mid-range throttle response are impressive – but it’s the top-end speed under a heavy load where the XS really shines. The only unknown is venting. With the Yamaha, the 1″ vent holes may produce too much venting while planing. Consider running the Bravo I FS with Mercury’s PVS vent system (3/4″ vent holes). To learn more, go to the Bravo I FS page on the Mercury Racing website. Scott

  36. Hey Scott, just want to say I love this prop and how it handles but I’m running high rps with the recommended setup which is what i’m running. I run a 2010 Ranger 620 with a 250 pro xs and 8 inch hydrolic Jack plate. The boat is rigged with a 9.9 kicker as well. It currently has a Bravo 1 XS 22p prop (not sure if lab finished or regular). The boat loaded up with fishing gear, 2 guys and full tank of fuel running WOT I’m getting 58-59.5 mph and running 6000-6150 rpms. I’m wondering if I should be running a 23p or 24p?? Also, I’m thinking with my setup I should be able to run in the 60s. My RPMs are higher than I want to run so I would like to know what you think. Thanks!

    1. Jared,
      Yes, you could move up in pitch to maximize your fuel economy and speed. By how much? Let’s work through it. First, the Bravo I XS is a hybrid of the Bravo I family, not Lab Finished and not stock. The XS version is in between the two and made with all the performance details. Next, boat set up and propping is constantly evolving. We’re continually learning (one of the many cool things about this job). As more Walleye rigs are equipped with jack plates, we are finding most applications allow a 2″ pitch increase change. Let’s look at what you could expect with a 23″ and 24″ pitch Bravo I XS. Starting with pitch, for every 1″ of pitch change we can expect the engine to change by 150 rpm. The 23″ pitch would drop 150 rpm from the 22″ pitch rpm range (6000 to 6150); down to (5850 to 6000). A 24″ pitch would drop it even further by 300 rpm or (5700 to 5850). For the speed, if you’re hitting 58-59.5 mph with the 22″ pitch then we can calculate the 23″ pitch should come in at 59-60 mph. The 24″ pitch would take you to 60-61; and possibly even as high as 62 mph. You know how strong the 22″ pitch accelerates. You could consider the 24″ pitch. Have fun and good fishing,

  37. I am wanting to try and new prop on my 2013 Ranger 620 with I hate to say it on this website but an Evinrude Etec 250HO. I read above that either the 25″ or 26″ Bravo 1 XS is the best prop on the boat. I will have a full tournament load on the boat most of the time. Anyone tried out both props and could give some insight before I order one? Thanks in advance.

    1. Bjorn,
      We won’t hold it against you. We’re just glad you’re looking at the Bravo I XS. Many E-Tec owners are struggling with the Evinrude props and have seen great improvements running the Bravo I XS or Bravo I FS. The Bravo I XS, with its large 1″ non-adjustable vent holes; can blow out while coming on plane with the E-Tec. We’ve recently added Mercury’s patented Performance Vent System (PVS) to the Bravo I FS prop. The FS features four .75″ PVS adjustable vent holes. Many E-Tec owners may not be aware of the upgrade. If you have a jack plate, most of the guys are running the 25″ pitch FS. If you’re without a plate, try the 23″ or 24″. Please contact Pamp’s Outboards our authorized Mercury dealer in Green Bay. They are a big user of the Bravo I XS and FS props on E-Tecs. Keep us informed with what you end up going with.

  38. Scott,
    This is a bit different application from the bass boat guys… A Stoker SST 204 (mod-vp) with 300XS, Sportmaster lower. Purchased boat with a Bravo1XS 28p. It produces a circular porpoise action (vertical and lateral) than is pretty un-nerving at high speeds (over 70). The boat builder (Al Stoker) drove to 95 and hit the limiter with this prop. He has thousands of seat hours, I’m in the low 100’s. However, I’d like a set that isn’t requiring this kind of experience. The problem I have with the Bravo is steering is VERY stiff when I start to jack the plate up so have to run it buried. Plan to put hydraulic assist on this summer. I really don’t know how it will behave even or above the center pod.

    I have tried a Fury 26p and it was much faster out of the hole and no hop to low 80’s,
    running well below the pod. I tried an ET 26p and performed well to 84 at 6100 rpms before backing off. No hop. Tried a Pro ET, and it needed a 5 degree right turn to keep the hop from starting and made 87 at about 5950 before I ran out of room. Hop didn’t seem to matter whether it was above or below the pod.

    The overhub props were terrible out of the hole, which was expected, especially the 26 ET. Not as concerned with hole shot… I’d like to run up to 90 without working so hard to get there (with the porpoise thing). It’s not very conventional, but I’m thinking the Fury in a 27p might fit the bill. The 3 blade 26p’s both seemed to behave better than the 28 four blades. I think the Bravo is just too big and starts to horse the back end around. Have no idea which of these is a bow vs stern lifter. Any thoughts after all this rambling? Thanks.

    1. Jon,
      Awesome rig. It’s got to be fun to drive. I thought Al likes the Bravo I XS. However, if it’s not right for you then you need to find something that gives you security at high speeds. If you are hitting the low 80s with the 26” Fury, I don’t see you approaching 90 by simply moving up one inch of pitch. Most drivers prefer 4 blades over 3 blades at high speeds. You simply have more blades in the water at any given time for enhanced handling. Three blades can be more unstable at higher speeds due to the limited number of blades in the water. You might consider the Pro Max as your next test prop. The small barrel may help during planing and may offer a smoother ride as you approach WOT.
      Have fun,

  39. Scott i was looking at the original post, I see you gain 100 rpm with the lab finish. Is this typical?

    I have the 22p Bravo XS without the lab finish now and like it, but I see the lab finish is a little faster also.

    1. Hi Kirt,
      Good to hear from you. Yes – the Lab Finished Bravo I blades are thinner than the Bravo I XS. The Lab is great if you’re just interested in top speed but for durability, with the thinner blades, there’s a greater chance a blade could fail. If you need a little more rpm, consider a 20″ or 21″ Bravo I FS. Running the lower pitch FS – with the .75” PVS vent holes (completely open) – provides adequate venting with the OptiMax.
      All the best,

  40. I’m seriously considering a New Crestliner Intruder with a 250 ProXS with a 6″ Hydraulic jack plate. It is a few pounds less than a Ranger 621 but it does have a 100 gal livewell in it which will only have water in it during tournaments. I was wondering if a Bravo 1 XS would be a good fit? If so any idea what pitch to start with 22 or 23?

    1. David,
      I’m a huge fan of the Bravo I XS for your new set up. I think you’re close on pitch. With a jack plate, you typically you can add 1″ of pitch (sometimes 2″). It’s tough to narrow it down without having some performance data to work with.

  41. I have tuffy 2060 with 225 optimax and ran 5400 rpm at 54 mph in middle hole . This was with a 22 inch bravo what do u recommend I drop down to to get rpms around. 5600 to 5700? I also have raised the engine one more hole position since this test . Thanks

    1. Ben,
      Typically, by raising the engine one hole or .75″ – the engine speed typically increases 100 to 150 rpm. If you want to test at the higher level – run your current prop first record your engine rpm. If the boat performs well at that height and you still want an additional 150 rpm then switch to the 21″ Bravo I FS. The Bravo I FS is offered in 20″ and 21″ pitch with (4) .75″ PVS vent holes. Removing all (4) solid fittings will allow the prop to ventilate for improved planing performance.

  42. I have a 2015 ranger 1850 reata with a merc 150 four stroke with a 19p trophy speed 45 spinning 5200 trimmed up rooster about even with top of engine hole shot is good just looking for better any info would be helpfull

    1. Troy,
      Using your speed and rpm numbers, your prop slip calculates (how well the prop is hooking up) at 7.7% slip which is awesome. Using a 17” pitch Trophy the engine rpm should raise 300 rpm to 5500 but the speed would unfortunately drop to 42.5 – 43 mph; faster planing but reduced top speed. A 21” pitch would drop the engine speed by 300 rpm to 4900; below the recommended range. I think you’re there with your set up. Enjoy.

  43. Hi
    I have a Trito 18 XS with :
    200 HP Mercury Verado
    Revolution 4 prop 23 Pitch
    RPM 5900
    Max Speed 59 MPH
    Im looking to be over 60+ MPH

    What would recommend for this case , maybe a Fury 24??

    1. Jose,
      Your engines rpm range is 5800 to 6400 and the 23″ pitch Rev 4 has the engine at the low end. The Fury’s run high in pitch. The 24″ pitch Fury could lower your engine speed by 100 to 150 rpm. It appears your boat runs good with the 4 blade so consider running the 24″ pitch Bravo I FS. The Bravo I FS is designed for a move up in pitch so running a 24” pitch should give your motor an additional 100 to 150 rpm with a great potential for increasing your speed by 2 mph.

  44. I’m running a tuffy 1890 with 150 verado an 19p tempest. 49.5 to 50.5 @6250rpm. My problem is poor holeshot,mid range response,slight porpise mid range,an falls off plane at anything less than 19mph. Will this motor handle the 20p bravo 1 fs. My motor is mounted low,second hole,so I feel I could raise a hole is I do need to. Or am I better off with a different idea?

    1. Greg,
      I agree with you about raising your engine. Raising it should offer additional rpm. I really like the idea of running the 20” pitch Bravo I FS. In addition to enhanced planing performance, you will notice you will be able to stay on plane at slower speeds as well. And, the stern and bow lifting characteristics of the FS should eliminate the porpoising.

      1. Scott
        I did find the issue with my holeshot,a panther trim shim had been installed between the transom an the motor,unfortunately it had been installed upside down,not allowing the motor to fully trim in. Holeshot is now acceptable,but I’m still thinking of trying the fs for better control at low speeds. The speeds/rpm listed above were fully loaded,51 gals,pro kicker,3guys,3 batteries an full gear it was pulling the tempest 19 @6250 50mph. So will raising the motor a hole an running a 20p fs be in the safe range for rpm? Or since the bravo is pitched lighter according to this thread will the motor raise get me to close to the rev limiter?
        The amount of weight in the boat does not seem to have much if any effect on the top end of this boat in either rpm or mph.

        1. Greg,
          If you keep maintain your engine height, the 20″ pitch Bravo I FS will offer similar rpm to the 19″ Tempest. If you raise the engine one hole or .75″ consider moving up to the 21″ pitch FS with the engine speed steady at around 6200 rpm.

  45. Scott

    I have been fortunate enough to run The bravo I XS in 22 and 24 P on my rig. I am looking for input on which pitch to order. I am running an 04 621 ranger with a 250 opti xs and a 6″ hydraulic jackplate. with the 22P I ran 58.5 mph and was bumping the rev limiter at 5850 at wot and not much trim. with the 24P I was able to run 61.5mph at 5650 at wot and full trim. Both runs were with 1 person, 1/2 tank of fuel and a small load. both props slipped some with all 8 holes open. once the props hooked up performance was good. the 24P was a bit slow to accelerate after it hooked up. with the 1/2″ pitch incraments available, I am not sure where I should land in between the 22 and 24P? I do fish tourneys in all big water conditions. Thanks for any input in advance!

    1. Jim,
      Glad you had the chance to run the two pitches. If all the PVS holes were open, consider adding two solid fittings opposite each other toward the rear of the prop. Consider splitting the difference – going with the 23″ pitch. Much of the performance depends on the additional weight added to the boat. The numbers you’ve provided should be good with the 23″ pitch. You may have already done this but – if not – consider testing with the engine height increased .5″ to .75″(be sure to maintain good water pressure and prop holding at WOT).

  46. I should also mention that both props ran best at 3-4 inches up on the jackplate, which is higher than the 1.5-3 inches up that my 21P tempest plus liked the best.

  47. Scott,
    I am hearing some really good things about the Bravo 1 for my set up. I have a 2016 Skeeter WX2060, 250 yamaha SHO with 8″ set back plate, 9.9 kicker w/8″ set back plate, troll motor, 4-group 31 batteries. It has a salwater series 2 19p, fully loaded, full tank of fuel (51 gal), two people, she will run 56 gps @ 5900rpm. Hole shot is good, it has tendency to purpose mid range rpms, and I feel that it needs a little more stern lift. The other thing that I have happen is when climbing waves, when I crest the wave and start down the back side, I will hear it cavitate a little. I primarily fish Lake Erie and want to have a prop that prop that is good in the slop. I would like as much top end as possible on those flat days, but not my top priority. Would a Bravo 1 FS be a good choice? How about pitch? Thanks

    1. Phil,
      Read the same message from Brian’s FS Experience with one addition; the LT will be perfect for Erie.
      I waited until our new Bravo I LT (read about it in the featured blog) was released to answer your question. A 4 blade is a great choice for your set up. Your comment regarding porpoising in the mid-range suggests the LT, with its long barrel, may be better suited to for your application to ensure maximum performance. The Bravo I LT is very similar to the FS. The difference is the longer exhaust tube/barrel. The added length should eliminate the loping. As for pitch, I believe the 19” pitch would run at a similar rpm as the 19” pitch Tempest. The 21” pitch Tempest should reduce the engine speed 300 rpm at WOT. If you want the same rpm as a 19” go with the 20” pitch LT. Enjoy.

  48. I’ve got a 2007 Triton 215 with an 07′ Optimax XS with 25″ shaft and fleetmaster gearcase, no Jack plate.
    It’s a relatively new boat to me, and was set up with a 24p Tempest. I’m hitting 58-mph at 5600rpm fully loaded with 2 guys and a full fuel tank.
    The boat gets up on plane quick, but porposes at lower- mid speeds.
    I’m hoping to find a prop that will run a little smoother at lower speeds, but still get me up around 60mph if possible.
    I’m looking to try a new prop and was thinking of trying a 24p Bravo XS.
    I’m also considering adding a 6″ jackplate to the boat, so i might have to take that into consderation when choosing a new prop.

    Any thoughts?

    1. Joe,
      Great idea with the Bravo I XS. The prop works extremely well with the 215 hull. The 25” pitch XS will offer similar rpm to the Tempest 24” at WOT. The jack plate will help take advantage of the 4 blade. The added blade enables it to run higher out of the water without loss of efficiency. You will want to raise you engine a minimum of .75” higher than the 3 blade engine height. Also plan to move up 1” to 2” of pitch.

      1. I have a 2019 Ranger 2080 with the 250 Mercury Pro XS V-8. The 21 tempest had great hole shot but could only get 5500 rpms and terrible chine walk and massive rooster tails. Switched to a 20 Pitch Bravo 1 fs, still great hole shot, no more chine walk and now I am at 5900 rpms. Is there a prop that will get the 6200 rpms and improve top end. Average top end is 52-54.

        1. Darren,

          You are not going to get much better than the performance with your Bravo I FS, I wouldn’t change a thing. You do not need to be all the way out at 6200 RPM for your motor, that is where the computer starts to pull out power, 5900 is very acceptable.


  49. I have a Lund 186 GL Fisherman, 175 verado with a kicker on the back. There was a 3 blade on the boat when I purchased it and it performed well above 35 mph, under that it was aweful. I contacted mercury about my issue and they told me to try the bravo FS 1 in 20. The prop changed the performance of the boat and it’s great with a half tank of fuel, lighter load and two guys. Put more weight in the boat and the hole shot is rough and it’s tough to keep the boat on plane at slower speeds especially in any kind of waves. Also the boat will porpoise but not terribly. The motor runs right around 5800 rpms at WOT and 48-50 mph no matter how much weight is added to the boat. The motor is in the second to the top hole and I can almost trim the motor all the way up to 10 before it starts to cavitate. I know I can raise the motor for better performance but I was wondering if there is a better solution (prop, maybe a 19” bravo LT ?) since I tend to run with a heavier load most of the time and need a better hole shot and keeping the boat on plane at slower speeds with no proposing? Thank you for any advice.

    1. Dave,

      I think you are right on the money with considering the 19 pitch LT. The longer barrel will improve hole shot, keep you on plane at lower speeds, and help with the porpoise. The drop in pitch should net you another 100-150 RPM.
