Performance Benefits

You’ll feel this prop’s performance the moment the throttle opens up. The Extra Cup blades dig into the water with authority, giving you strong lift and a solid, confident push through the midrange. It’s a prop that grips without slipping, giving your boat that steady, planted feel even when conditions get unpredictable.

The Mercalloy aluminum build is a sweet balance of toughness and flexibility — sturdy enough to handle the occasional bump from floating debris, yet light enough for quick acceleration. The Phantom Black glossy finish keeps corrosion at bay and gives your setup that clean, polished look long after a full season of use. And when it comes to handling, the Black Max keeps things smooth. Turns feel predictable, docking is easier, and the ride is quiet enough that you’ll notice the wind before you notice the prop.

Maintenance is as simple as it gets: rinse it off, check the hub now and then, and you’re ready for another weekend run. This prop was made to handle real-world boating, not just showroom conditions.
