Gear: Mercury Racing launches recreational propeller rated to 600hp
US boat owners now have access to a performance prop rated for Mercury Racing’s 8.2-litre V8 sterndrive enginesMercury Racing has released a high-horsepower CNC-milled propeller for sterndrive boats to suit a new generation of boats that blur the line between racing and pleasure.
The new five-blade prop is rated to 600hp, and features 1.25-inch broached splines.
“With all the buzz surrounding the latest and greatest outboard power, it is easy to overlook the great sterndrive packages that boat-builders are producing,” Mercury Racing said while announcing the new prop at the weekend.
“The West Coast continues to be a stronghold for lightning fast sterndrive-powered catamarans and vee bottoms, typically equipped with 502 cubic inch-based powerplants.”
The Cleaver propeller is designed for Bravo XR Sport and Sport Master drives that use Mercury Racing’s 8.2-litre V8-powered 520, 525, 540, 565, and supercharged 600 SCi inboard engines.
High-speed applications
“For high-speed applications, this new development gives Bravo XR users the opportunity to run our most advanced propeller technology, which was previously only available for M6 and M8 drives,” Mercury Racing said.
The first two boats to feature these propellers are a DCB F29 equipped with twin Mercury Racing 525, and an Outerlimits SV29 equipped with a single Mercury Racing 600 SCi. Both applications have reported significant improvements in mid-range acceleration and top speed gains of 5 mph above standard cast propellers.
In the US, the prop will be available in 14.75- to 15.50-inch diameter, 26 to 40 pitch, and 15- and 18-degree rake.
