Performance Benefits

The Black Diamond 9.3" x 11" delivers the kind of steady, no-nonsense performance that makes every trip feel effortless. From the moment you throttle up, it grips the water with confidence — no lag, no hesitation, just smooth acceleration that gets your boat up on plane quickly. Once you’re cruising, it holds its course with ease, giving you that reassuring sense of control through turns and open stretches alike.

Its three-blade design is tuned for smaller engines, striking the right balance between thrust and fuel efficiency. Around docks and shallows, you’ll appreciate how responsive it feels — quiet, composed, and predictable. And when the water gets choppy, it keeps a firm grip without excessive vibration or pull.

The Phantom Black finish is more than just sleek — it’s tough. It resists corrosion, salt buildup, and scratches, keeping maintenance simple. A quick rinse after a day on the water is all it takes to keep it looking good. The aluminum build also offers a bit of forgiveness that stainless steel props don’t — if you bump a rock or brush a sandbar, you’re not looking at an expensive replacement. This is a prop built to work hard and last.
