Performance Benefits

The Mercury Enertia 3-Blade Propeller was designed for boaters who crave acceleration as much as smooth cruising. When you hit the throttle, it reacts instantly — you’ll feel that clean, aggressive pull as your boat rises to plane with effortless lift. Once you’re up and running, it balances speed and stability beautifully, keeping your turns confident and your handling predictable even when the water gets choppy.

Thanks to its X7 stainless steel construction, this prop holds its shape under stress, maintaining pitch accuracy and performance long after standard stainless props begin to flex or fade. The result is consistency — the kind that keeps your boat performing like new season after season.

Add in Mercury’s Performance Vent System, and you can fine-tune your acceleration by adjusting the exhaust venting to match your load or water conditions. That flexibility means you’ll get the exact hole shot you want — whether you’re pulling skiers, running light and fast, or pushing through heavier loads.

It’s fast, forgiving, and built to handle whatever your boating day brings — from calm mornings on the lake to long afternoons under full throttle.

Why is this prop a strong choice vs. alternatives?

• Mercury OEM Quality: Built by the same engineers behind Mercury’s legendary engines, ensuring a perfect fit and reliable performance.

• Superior Strength: The X7 stainless steel alloy gives it unmatched durability — 30% stronger than traditional stainless, resisting flex and fatigue.

• Versatility: Performs across multiple setups — outboards, sterndrives, pontoons, or sport boats.

• Tuned Performance: Customizable with the PVS system, allowing you to tweak hole shot and acceleration for your specific setup.

If you want a propeller that turns your boat into something sharper, quicker, and more connected to the water — this is the one you’ll remember after every ride.
