Performance Benefits

The Mercury Enertia 3-Blade Propeller isn’t just about getting from point A to point B — it is about how you get there. The acceleration feels effortless, with the prop biting into the water and lifting your hull onto plane without hesitation. Once you’re up to speed, it’s remarkably smooth, holding a steady grip even when the water gets unpredictable. You’ll feel that balance between power and control, where turns are clean and the boat feels lighter in your hands.

Crafted from Mercury’s X7 stainless steel alloy, the Enertia is as tough as it gets. It resists flexing under heavy load and maintains its pitch integrity longer than standard stainless props. That means consistent performance season after season — no loss of lift, no dulling of responsiveness. And with the Performance Vent System (PVS), you can dial in your setup for your exact needs, adjusting your vent plugs to get that perfect hole shot based on load, elevation, or water conditions.

For boaters who care about both speed and smoothness, this prop delivers the best of both worlds. It’s built to run hard, corner clean, and handle whatever the water throws at you.

Why is this prop a strong choice vs. alternatives?

• Mercury OEM Precision: Engineered by Mercury for perfect harmony with their outboards and sterndrives.
• Unrivaled Strength: The X7 stainless steel is 30% stronger and four times more durable than traditional stainless, giving you unmatched longevity.
• Customizable Performance: The PVS system lets you tune hole shot and acceleration to your exact setup.
• Versatility: Equally at home on pontoons, family boats, and sport setups — one prop that adapts to all.

If you’re looking for a prop that rewards precision and delivers consistency — one that feels alive under the throttle — the Enertia 3-Blade is the one you’ll talk about long after the day’s over.
