The moment you ease the throttle forward, you’ll feel it — the Black Max catches the water with confidence, bringing your boat up on plane iin one quick, natural movement. The acceleration feels natural and responsive, giving you confident control through every turn. Once you’re cruising, it holds steady — no chatter, no slipping, just smooth, balanced power that feels effortless under your hands.

Mercury’s Mercalloy aluminum strikes that ideal balance between strength and forgiveness. It’s tough enough to handle the knocks and surprises that come with real-world boating — a stray branch, a sandy bottom — without giving up its performance edge. The Flo-Torq Reflex Hub Kit adds another layer of protection, reducing vibration and cushioning your drivetrain from small shocks. The result is a quieter, smoother experience that makes long runs more enjoyable and less stressful on your motor.

Maintenance stays simple too. A quick rinse after a day on the water and it’s ready for the next trip. The Phantom Black enamel finish isn’t just about looks — it’s engineered to stand up to corrosion in both saltwater and freshwater, keeping your prop looking sharp and running strong season after season.
