Performance Benefits

The Mercury Black Max Extra Cup Propeller is all about reliable performance and smooth control. You’ll feel it the moment you throttle up — the prop grabs the water with solid traction, pulling your boat onto plane quickly without hesitation or cavitation. The extra-cup blade design enhances grip and lift, giving you better handling and midrange power, especially when carrying passengers or gear.

Once you’re cruising, the Black Max feels steady and predictable. The three-blade configuration offers a comfortable balance between acceleration and efficiency, while the Mercalloy aluminum construction absorbs small impacts better than stainless steel — protecting your drivetrain and keeping maintenance low. It’s a forgiving prop that works just as well for weekend cruising as it does for serious fishing or towing.

The included Flo-Torq SSR Hub Kit takes things a step further. It reduces shift clunk for quieter gear engagement and cushions your outboard’s drivetrain against potential impact damage. The result is a prop that feels refined and professional, even on smaller boats. And thanks to Mercury’s Phantom Black enamel finish, corrosion doesn’t stand a chance — this prop holds its color and integrity in both saltwater and freshwater environments.

At cruising speed, you’ll appreciate its consistency. The prop’s smooth rotation and efficient design help maintain steady RPMs, improving fuel economy over longer runs. When conditions get choppy or currents shift, the Black Max stays planted, holding bite and maintaining control without slipping. It’s performance that feels natural and easy like the boat’s doing exactly what you ask of it no surprises.

Why is this prop is a strong choice vs. alternatives?

If you’re looking for a propeller that’s strong, efficient and affordable, the Mercury Black Max (8M0151356) is a proven choice. It’s engineered with real-world boating in mind — where you need a mix of power, protection, and value.

Unlike many entry-level props, the Black Max doesn’t cut corners. Its Mercalloy aluminum construction gives it strength beyond standard alloys, yet it’s ductile enough to handle minor impacts without cracking. The extra-cup design adds lift and control, which is especially noticeable on pontoons or heavier boats that need a little more push. It’s a prop that feels balanced and confident, even when conditions aren’t perfect.

Because it’s an original Mercury propeller, you’re getting years of research and refinement behind every blade. It’s not just a budget option — it’s a dependable performer that’s easy to maintain and ready for anything.
