It’s fast, responsive, and engineered to make your boat feel lighter and more alive under your hands.

Performance Benefits
The Mercury Enertia 3-Blade Propeller is all about effortless power and precision. When you throttle up, the blades dig in and launch your boat onto plane with clean, assertive lift. You’ll notice how quickly it reacts — there’s no sluggishness, no lag, just instant thrust and a smooth rise. Once you’re running, it delivers that perfect balance of top-end speed and reliable grip, even in rougher conditions.
The X7 stainless steel alloy sets this prop apart from the crowd. It’s tougher and stiffer than standard stainless steel, meaning it won’t flex under load. That translates into consistent pitch and performance run after run, season after season. And with Mercury’s Performance Vent System (PVS), you can adjust how your prop ventilates on takeoff, customizing your hole shot and acceleration based on your boat’s load or your own preferences.
This prop doesn’t just perform — it makes driving more enjoyable. It’s smooth, predictable, and forgiving, letting you focus on the experience instead of the mechanics.
