Mercury Racing Lab Finished Bravo I propellers feature the durable high polish finish; designed for high-performance, high gearcase drive height Verado outboard and Bravo I sterndrive applications. Excellent top speeds, great handling, good mid-range speeds and great planing performance for V bottoms, Cats, and Step hulls.
The Lab Finishing process includes wedging the leading edge so the prop cuts into the water verses chopping; the blades are thinned in areas while maintaining integrity, the trailing edge cup height is modified to gain 300 RPM and new in 2014 the finish is high polished.
Because of the 300 RPM gain consideration should be given to increase 2 inches of pitch over a stock Bravo I.
