The Mercury Enertia 3-Blade Stainless Steel Propeller (Part Number 8M0151235) captures that feeling every time you throttle up. It’s quick, confident, and precise — a prop that doesn’t just move your boat forward, but makes it feel alive beneath your hands. Whether you’re cutting through calm water or running wide open with a full crew on board, the Enertia keeps you connected to the ride in a way that’s hard to forget.

Performance Benefits

The Mercury Enertia 3-Blade Propeller is built for those who care about how a boat feels on the water — not just how fast it goes. From the moment you throttle up, you’ll notice the difference. The blades bite cleanly into the water, giving you instant lift and acceleration that feels smooth and natural. The transition from idle to plane is quick and balanced, letting you focus on the ride instead of fighting the prop.

Once you’re up and running, the Enertia shines with its combination of speed and control. It grips the water through turns and holds steady in choppy conditions, giving you that confident, planted feeling at the helm. Its X7 stainless steel alloy is a game-changer — a proprietary Mercury material that’s stronger and stiffer than conventional stainless steel. That means no flexing under load, no performance loss over time, and consistent pitch accuracy no matter how hard you run it.

Then there’s Mercury’s Performance Vent System (PVS), which lets you fine-tune your setup. By swapping vent plugs, you can control how your prop ventilates during takeoff — perfect for customizing acceleration based on your boat’s weight, load, or water conditions. It’s an added level of precision that turns every launch into a confident start.

The Enertia’s design combines raw power with refinement. It’s not just about getting on plane — it’s about how smooth, steady, and predictable that ride feels once you’re there.

Why is this prop a strong choice vs. alternatives?

• Mercury OEM Engineering: Built and tested by the same engineers who design Mercury’s world-class engines for seamless fit and performance.
• Unmatched Strength: The X7 stainless steel alloy provides 30% more strength than conventional stainless, resisting flex and fatigue.
• Tunable Acceleration: The PVS system allows you to adjust venting for faster hole shots or smoother launches.
• Reliable Control: Maintains smooth handling and steady tracking even at high speeds or under heavy load.
• Long-Term Value: Corrosion-resistant construction and consistent performance season after season.

If you’re looking for a propeller that transforms how your boat accelerates, corners, and cruises, the Mercury Enertia 3-Blade is one you’ll keep coming back to. It’s built for the boater who expects not just performance, but precision and confidence in every run.

FAQ

Q1: Which Mercury engines does the Enertia 3-Blade Propeller fit?

It fits Mercury and Mariner 90–115 HP Command Thrust outboards, Mercury 135–350 HP TwoStroke and FourStroke outboards (excluding V10 Verado), and MerCruiser Alpha One and Bravo One sterndrives.

Q2: What makes this propeller different from other Mercury options?

The Enertia is made with Mercury’s exclusive X7 stainless steel alloy, making it 30% stronger than conventional stainless. It’s designed for higher speeds, faster acceleration, and long-lasting durability.

Q3: How do I know if this pitch or size is right for my boat?

A 17" pitch prop is a great fit for midsize to large boats that need quick acceleration while maintaining strong cruising performance. Verify your engine’s recommended RPM range for ideal results.

Q4: Can this prop be used in both saltwater and freshwater?

Yes. The polished stainless steel finish protects against corrosion in both environments for long-term reliability.

Q5: What hub system does it use?

It requires a Mercury Flo-Torq hub kit (sold separately), which helps absorb drivetrain shock and ensures smooth, secure installation.
