Performance Benefits.

The Mercury Quicksilver Black Diamond 9" Pitch Mercury propeller delivers the kind of dependable performance that makes boating feel effortless. When you throttle up, it bites into the water with just the right amount of grip — strong enough to lift you onto plane quickly, yet smooth enough to feel controlled. You won’t get that jarring jump or hesitation, just clean, steady acceleration that feels natural from start to finish.

Once you’re underway, the difference in balance becomes clear. The 3-blade design keeps the ride stable through turns and chop, maintaining consistent thrust even when conditions get unpredictable. It tracks true at cruising speeds and stays responsive at low speeds, making docking or maneuvering easy and precise.

This prop also shines when it comes to fuel efficiency. Its lightweight aluminum construction and refined blade geometry help reduce drag and convert torque into usable thrust more effectively. That means better mileage, less vibration, and a quieter, more relaxed ride.

And when it comes to maintenance, you’ll appreciate its practicality. The Phantom Black finish not only looks sharp but also protects against corrosion and minor wear. Aluminum construction keeps it affordable to repair or replace — perfect for everyday use or as a dependable backup prop.

It’s a great choice for new boaters, casual cruisers, or anyone who wants a prop they can count on without overcomplicating things. Whether you’re running rivers, lakes, or bays, this prop delivers dependable thrust and smooth control at a value that’s tough to beat.
