Performance Benefits

On the water, this Mercury propeller feels smooth and responsive. You’ll notice quick, confident acceleration—especially when getting onto plane or navigating tight spaces. It grips well in turns and delivers steady lift when cruising at midrange throttle, helping the boat feel balanced and easy to control. The aluminum Mercalloy build has just enough flex to absorb minor impacts, which means you’ll spend less time worrying about hidden stumps or shallow launches. Add in the rubber hub’s ability to cushion the drivetrain, and you get less vibration through the tiller and a noticeably quieter ride. Maintenance is minimal—just a rinse and a check, and it’s ready for another weekend.

It’s engineered by Mercury’s own team—the same minds designing the engines it powers—so you know the fit and performance will be spot on. It’s also an affordable way to get genuine OEM quality without cutting corners. Whether you’re running a small fishing skiff, a tender, or a lightweight cruiser, this prop delivers that familiar Mercury dependability and smooth handling that keeps you out on the water longer and heading back with a smile.
