Performance Benefits

The Mercury Black Max 832830A45 is all about balance—the kind that makes boating feel effortless. Its 19-pitch setup hits the sweet spot between quick planing and smooth cruising. The prop “grips” the water when you accelerate, lifting the hull evenly and holding steady through turns or rough chop.

Mercury’s Mercalloy aluminum makes it both tough and forgiving. It’s strong enough to stand up to demanding conditions but flexible enough to absorb minor impacts that could damage stiffer materials. Pair that with the Flo-Torq II Hub System, and you get quieter operation, reduced vibration, and less wear on your drivetrain over time.

The Phantom Black enamel finish adds durability and style, keeping corrosion at bay even after seasons of saltwater or freshwater runs. The result is a prop that looks great and performs even better—year after year.
