Performance Benefits

When you hit the throttle, the Revolution 4 answers with confidence. Its four-blade layout gives your boat a strong, steady grip that’s immediately noticeable. You will feel it launch smoothly onto plane — no hesitation, no excessive bow rise — just clean power that translates straight to forward motion. At cruising speed, it holds the water with precision, keeping your boat level and responsive even through sharp turns or wind-blown chop.

The deep-cup design adds extra bite in midrange performance, giving you the kind of low-end punch that gets heavy boats moving fast while maintaining steady lift for towing and load-carrying. It’s the perfect balance of muscle and refinement — fast when you want it, forgiving when you need it.

Mercury’s Performance Vent System (PVS) lets you tailor the prop’s hole shot to your exact setup. By swapping vent plugs, you can fine-tune acceleration and load handling for your specific conditions — whether you’re towing, trolling, or running light and fast. Built from corrosion-resistant stainless steel, the Revolution 4 is designed to handle years of use in both freshwater and saltwater without losing its edge.

This is a prop you’ll trust in big water — the kind that delivers steady control when conditions demand your full attention.
