"Designed for outboard and sterndrive applications, the Mercury Racing Bravo I®FS propeller delivers unmatched time-to-plane performance, mid-range punch, mid-range cruise and top-end speeds for outboard bass, flats, cat flats, bay boats, offshore center consoles and sterndrive deck and vee bottoms under medium to heavy load. The patented Mercury®Performance Vent System® (PVS®) enables operators to dial in a propeller for peak planing performance. The PVS®system works in concert with robust blades that are hand blended and balanced by our propeller lab artisans. The tuned exhaust tube minimizes stern lift for enhanced bow lift, handling and overall boat performance. Four-stroke outboard and sterndrive applications will use the Bravo I®FS with all four vent holes plugged with solid PVS® fittings. Larger, heavier multiple engine applications may benefit by taking one or two fittings out for improved planing. To maintain similar engine operating rpm in single engine applications, switching from a Tempest® Plus to the Bravo I®FS would require a 1-inch increase in pitch. A switch from the Fury®and Revolution 4® to the Bravo I®FS would require a 2-inch increase in pitch"
