Performance Benefits

The Mercury Enertia 3-Blade Propeller transforms every throttle push into pure, confident motion. When you accelerate, you will feel the prop grab water instantly — no delay, no slip. The lift is smooth and balanced, getting your boat on plane faster and holding it there effortlessly. Once you’re running, the Enertia gives you that steady, predictable control that makes driving feel intuitive — even when you’re slicing through choppy water or tight turns.

This prop’s strength lies in its X7 stainless steel alloy, Mercury’s exclusive metal formula that’s 30% stronger than traditional stainless. It holds its shape under heavy stress, so you’ll enjoy consistent pitch accuracy and performance even at high RPMs or under load. The result? Season after season of strong, reliable thrust and smooth operation.

Then there’s the Performance Vent System (PVS) — a feature you’ll come to appreciate the more you use it. By swapping vent plugs, you can fine-tune your boat’s hole shot and acceleration response to match your conditions, whether you’re running light, loaded, or towing. It’s that level of control that makes the Enertia a true performance upgrade for any setup.

When you’re behind the wheel, this prop just feels natural — balanced, steady, and built for fun.

Why is this prop a strong choice vs. alternatives?

• Mercury OEM Quality: Designed and tested by Mercury engineers for perfect compatibility and lasting reliability.
• Unmatched Durability: The X7 stainless steel resists flexing, fatigue, and corrosion far better than traditional stainless props.
• Customizable Performance: Mercury’s PVS system lets you tune acceleration and hole shot for your boat’s specific needs.
• Smooth, Predictable Handling: Keeps your boat steady and responsive across a wide range of speeds and conditions.
• Long-Term Value: Stronger materials and smarter engineering mean consistent, worry-free performance season after season.

This isn’t just a prop — it’s your connection to the water. The Enertia 3-Blade gives you that unmistakable feeling of control and balance that makes boating more than a pastime — it makes it a passion.
