Performance Benefits

The Mercury Revolution 4 Propeller delivers the perfect mix of lift, control, and power. Its four-blade design creates incredible midrange thrust, getting heavy boats on plane quickly while keeping the ride smooth and stable. You’ll feel the difference immediately — the prop digs in deep, gripping the water with authority, and pushing your boat forward with steady, predictable acceleration.

At cruising speeds, it’s all about smoothness. The Revolution 4 reduces slip and ventilation, giving you a consistent, efficient ride across a wide range of conditions. It tracks straight and holds tight in turns, even when the water gets choppy. The deep-cup blades add grip, keeping your hull planted while maintaining excellent lift and responsiveness.

When you’re running offshore or towing a heavy load, this prop’s balance really shines. It holds its bite when trimmed high, maintains thrust through turns, and gives you precise control when it matters most. You’ll notice how much easier it feels to handle rough conditions — no sudden loss of grip, no vibration, just steady, reliable thrust.

Built from premium stainless steel, the Revolution 4 is made for the long haul. It resists corrosion and flex, maintaining its performance season after season whether you’re in freshwater or saltwater. The Performance Vent System (PVS) lets you fine-tune your setup for faster hole shots or smoother acceleration, so you can dial in performance that feels perfectly tailored to your boat.

Why is this prop is a strong choice vs. alternatives?

If you’re looking for a propeller that combines power, precision, and durability, the Mercury Revolution 4 is one of the smartest upgrades you can make. It’s engineered by Mercury’s team of performance experts — the same people who build the engines it’s meant to complement — which means every blade, cup, and curve has been tested to deliver real-world results.

What sets it apart is how it feels under load. The Revolution 4 transforms heavier, deeper-hulled boats into confident performers. It accelerates faster, planes sooner, and handles more predictably than many three-blade props. You’ll gain not just speed, but balance — that solid, planted feeling that makes long runs or tight turns second nature.

Because it’s an OEM Mercury propeller, you’re getting reliability that’s backed by decades of engineering. It’s tough, adaptable, and designed to work seamlessly with your Mercury outboard or sterndrive. From weekend family rides to long offshore hauls, this prop keeps you in control, efficient, and enjoying every second on the water.
