It gives you confident grip in the water without overworking your engine, making it ideal for those quiet mornings on calm lakes or steady runs down the channel.

The Mercalloy aluminum alloy used in this Mercury propeller offers both strength and flexibility, giving it just enough give to handle a light bump or two without losing shape. It’s forgiving when you need it, but still tough enough to handle long weekends of use. The rubber-cushioned hub takes care of vibration and noise, protecting your motor while giving you a smoother, quieter ride. You’ll notice less chatter through the tiller and more comfort in your hand — proof that Mercury’s attention to detail pays off every time you push the throttle.

This isn’t a flashy upgrade; it’s a dependable partner that delivers what you need — performance you can feel and quality you can rely on.

It’s less likely to damage your lower unit in a shallow scrape and simple to maintain season after season. Mercury’s Phantom Black enamel finish helps keep corrosion at bay, whether you’re boating in saltwater or freshwater. For boaters who value simplicity and real-world dependability, this propeller just makes sense — it’s proof that sometimes, the best gear is the gear you can forget about because it simply works.
