Lightning E.T. Propeller – Don’t Fix What Isn’t Broken

We live in a world of fast-paced technological innovation; many consumer products are being replaced or updated quarterly or even monthly. Mercury Racing® embraces wide-open innovation and the concept of constant product development, but we also believe in the old axiom “don’t fix what’s not broken.” Which is why, 25 years after its introduction, the Mercury Racing Lightning E.T.® propeller remains in our product line. The Lightning E.T. is no legacy product. It is still running strong as one of the most-efficient propellers for lightweight, two-stroke outboard-powered applications.

There’s been a surging interest in outboard drag racing and for competitors running our lightweight, high-revving Mercury Racing 2.5 liter motors, the Lightning E.T. continues to dominate, offering outstanding acceleration and top-end speed performance. What makes the Lightning E.T. so efficient? Its over-the-hub design, limited blade area and ample tip cupping combine to produce a propeller that spins up quickly and stays hooked up at high engine heights. The Lightning E.T. produces natural bow lift, thus requiring less trim for maximum speed – less horsepower is used to lift the boat and more is devoted to top-end speed and acceleration. With the Flo-Torq II Delrin® Hub System, the Lightning E.T. accepts both 1.0- and 1.25-inch solid hub kits for legacy CLE, 2.5 liter Sport Master, and 3.0 liter Sport Master gear cases.

In recreational applications, the Lightning E.T. shines on river runs and performance bass, flats and modified vee bottom boats. The Lightning E.T. provides a confidence-inspiring ride for hulls that generate lift at speed, on boats from Allison to STV and everything between. The Lightning E.T. has done it for 25 years and is still leading the way. What is your favorite Lightning E.T. equipped setup?

A New Era for High-Performance Bass Boats

MAX5ST
Launched at the 2019 Miami International Boat Show, the Mercury Racing MAX5 ST the hottest new propeller for lightweight, single-engine bass boat capable of exceeding 85 mph.

The recent design evolution by leading builders of high-performance bass boats will leverage the performance of new four-stroke outboard motors offered by Mercury Marine and Mercury Racing. These boats are faster than ever, easier to fish, and better for the environment.

For anglers seeking more velocity on their way to the perfect fishing spot, the 4.6-liter V8 Mercury Racing 300R outboard and new propeller offerings from Mercury Racing have been a game-changer during the 2019 season. The all-new five-blade Mercury Racing MAX5 ST propeller paired with the Mercury Racing 300R has proven to be the perfect match for many high-performance bass boats. The five-blade MAX5 ST offers great hole shot and low slip percentages throughout the RPM range to deliver optimal fuel economy and top end speed on many bass boat models. Here are a few examples.

 

Allison Boats

The company perhaps most-synonymous with ultra-fast fishing rigs is Allison Boats of Louisville, Tenn., and its XB-21 BasSport models are a great platform for both the Mercury Racing 250R and Mercury Racing 300R outboard models. The highly efficient XB-21 hull is packed with high end fishing technology and Mercury Marine’s advanced range of controls. After extensive propeller testing, we’ve determined that both the four-blade Mercury Racing Pro Max and 15-inch diameter Mercury Racing MAX5 are great propeller options for this setup. The 15.25-inch Mercury Racing MAX5 ST is a great match for the Allison XB-21 BasSport 2+2 models rigged with Mercury Racing 300R power.

Bullet Boats

Bullet Boats offers several models of 20-foot to 21-foot 10-inch length that may be equipped with a Mercury Racing 250R or Mercury Racing 300R outboard. In our testing with this Knoxville-based builder the Mercury Racing Bravo I FS propeller is a great choice, but to squeeze the most performance from either outboard model on a Bullet bass boat there really is no comparison to the MAX5 ST. The MAX5 ST provides lightning-fast hole shot and less than 10 percent slip, which improves fuel economy and top-end speed. Both the Mercury Racing Bravo I FS and MAX5 ST props feature tuned, shortened barrels for reduced stern lift and have pushed lightly loaded Bullet Boat models rigged with a Mercury Racing 300R outboard beyond 100 mph.

Ballistic Boats

Ballistic Boats of Fruitland, Idaho, is a relatively new entrant into the high-performance bass category. Its single model, the 22-foot 3-inch Ballistic .223, features an all-glass helm display and vacuum-infused construction, and has topped 90 mph with a legitimate tournament load and a single person aboard when running the Mercury Racing 300R and MAX5 ST prop. According to Ballistic owner Jim Wells, some owners prefer the Mercury Racing Bravo I FS for its outstanding hole shot and mid-range performance, and top speeds in the mid-80 mph range. We look forward to seeing more Ballistics on the water with Mercury Racing 250R and Mercury Racing 300R outboard power!
