At the end of 2015, Mercury Racing unveiled two new versions of the stainless-steel Revolution 4 four-blade propellers. The Pro Finish Rev 4 XP provides precision for dialing in multi-engine, stepped-bottom center consoles and single-engine bay boats. It’s a popular wheel for the Mercury Verado 350 and Mercury Racing Verado 400R outboards. The XP model extends the pitch range of the Rev 4 series from 18- to 25.5-inch pitch sizes in half-inch increments. With so many pitch sizes available, boat owners can get maximum performance and efficiency out of their boats.
The new Pro Finish Rev 4 XC prop is designed specifically for single-outboard-powered hulls and features what Mercury calls an “extreme” amount of blade cup. The Rev 4 XC comes in 15- and 17-inch-pitch sizes to complement the Bravo 1 XC, which comes in 20-, 22- and 24-inch pitch sizes. The enhanced cup lets the engine run in elevated transom heights without sacrificing performance. This makes the propellers attractive for owners of flats boats who run in skinny water. The larger blade area allows the prop to stay hooked up for quick planing and enhanced performance through the powerband.
