Performance Benefits

When you drop the throttle, the Black Max 16438A45 hooks up clean and strong. The 14-pitch setup gives you a responsive push out of the hole, while the three-blade design holds a steady grip through corners and choppy water. It’s smooth when you want it to be and gutsy when you need it to be — the kind of balance that keeps your boat predictable and your passengers comfortable.

The Mercalloy construction gives this prop its character. It’s light enough for quick acceleration but tough enough to shrug off small knocks from debris or sandbars. Add in the Phantom Black finish, and you get corrosion resistance that stands up to both freshwater lakes and coastal runs. Maintenance is simple — just rinse and check your hub once in a while — and it’s ready for your next trip.
