Performance Benefits

The Revolution 4 is all about confidence — the kind that comes from a prop that feels planted, powerful, and predictable. When you throttle up, the four blades dig in and launch your boat onto plane faster than you’d expect from a heavy rig. The deep-cup design gives you instant midrange punch and crisp response, while maintaining smooth control as you climb to top speed. You’ll notice how the boat stays flat through acceleration and holds steady in tight turns, even when the water gets rough.

This prop excels in conditions where others might slip or lose bite. The four-blade configuration provides more holding power, letting you maintain grip at lower planing speeds — perfect for tow sports, trolling, or handling heavy loads. At the same time, Mercury’s Performance Vent System (PVS) allows you to tune how aggressively it hooks up, giving you control over hole shot and throttle feel. Built from premium stainless steel, the Revolution 4 resists corrosion, flex, and fatigue, ensuring years of reliable use whether you’re in freshwater lakes or offshore swells.

It’s the kind of prop that inspires trust. You’ll feel the difference in every launch, every turn, and every mile of clean, steady cruising.

Why is this prop a strong choice vs. alternatives?

• Mercury OEM quality with proven engineering and testing behind every design
