Performance Benefits

The Revolution 4 is built for boats that do it all — from long runs across big lakes to towing kids behind the boat on a warm afternoon. The deep-cup design and extra blade area give it outstanding midrange punch and lift, helping heavy boats get on plane faster and stay there with less throttle. You’ll notice how steady it feels — even in rough water, it holds its bite and keeps your ride smooth.

That Performance Vent System (PVS) is the secret weapon here. It lets you fine-tune your hole shot by swapping vent plugs, dialing in just the right balance of exhaust flow for your engine and setup. It’s the kind of small detail that makes a big difference once you’ve tried it. Add to that its stainless-steel toughness and corrosion resistance, and you’ve got a prop that’s built to perform year after year without losing its edge.
