Performance Benefits

The Revolution 4 Propeller isn’t just about raw power  it’s about control at every stage of the ride. The fourblade design digs deep, giving you a fast, confident hole shot that gets heavy boats up on plane quickly. Once you’re running, it delivers solid grip in the turns and stays locked in through waves, wakes, and tight maneuvers. You’ll feel the boat respond instantly, whether you’re throttling hard or cruising steady.

At midrange speeds, it’s smooth and balanced  that’s where this prop really shows its character. The deepcup blades hold their bite without over-revving, giving you a sense of calm command even when conditions turn rough. It’s the kind of performance that makes every throttle adjustment feel effortless. Built from premium stainless steel, the Revolution 4 is as tough as it is refined, built to resist corrosion and perform season after season in both saltwater and freshwater.
