The official start of Summer is June 21. If the volume of blog comments, voice mails and prop orders are any indication, the summer boating season has been under way for a good month already. I, like you, am ready to get some boating in and enjoy the warm summer weather. And – just in time for the season, I’m pleased to announce the official release of two new props that expand the versatility of our popular Mercury Racing Bravo and Maximus propeller lines.
Bravo for Outboard Cats!


Newly released this week is our all-new Bravo I OC (Outboard Catamaran) prop. The Pro Finish Bravo I OC was designed specifically for high powered outboard catamaran hulls. The new Mercury Racing Bravo features a total of eight PVS vent holes for fine-tuned performance.
The Bravo I OC diameter is cut down to 14.75″ and features a pitch range of 28″ to 35″ (even and odd) sizes and left and right hand rotation. A shortened exhaust barrel settles the stern to minimize drag while reshaping the blade maximizes performance with the new diameter. The prop has been tested on 28-foot to 32-foot Skaters, Talon, DCB, Spectre and Doug Wright hulls. It outperformed three and four blade cleavers in both acceleration and top-end speed (medium to heavy loads).

Maximus ST


Designed for sterndrives and big horsepower outboards, the Pro Finish Maximus ST (short tube) propeller is available in 24″ to 34″ (even) pitch sizes in both left and right-hand rotation. It too features a cut-down diameter (15.6” to 15.3”) and a shortened exhaust tube for enhanced performance. The Maximus ST is rated for up to 600 h.p. Dave’s Custom Boats of El Cajon, California helped validate this latest generation of our high performance Maximus line. DCB’s Dave Hemmingson and Tony Charimonte liked the STs so much they asked if they could use them for the Desert Storm Poker Run Shoot Out. They installed 32″ STs on Terry and Sandy Everson’s beautiful M29. The boat is powered by twin 565s coupled to 1.35:1 Bravo One XR Short Sport Master drives with Integrated Transom Systems (ITS). Terry and Sandy won their class in the shootout; bumping the rev limiter at 115 mph! Tony said, “the 565s pull so hard – we could have used 34″ pitch STs.” “We really like what Mercury Racing has done with the latest generation Maximus props,” Tony said. DCB is building a new M31 which will again feature the stout 565 sterndrives and Maximus ST props. We’re anxious to get the numbers on that one as well.

We’re very excited to offer these two new props. I’ve received a number inquires regarding both. Outboard cat owners are excited to bring new life to their performance hulls powered by our classic 2.5 EFIs or the epic OptiMax 300XS. The Maximus is waking up both four stroke outboards and sterndrives on a variety of applications. I look forward to hearing from you regarding these or any of our Mercury Racing props. Be safe and have a great summer!
