Performance Benefits

You’ll notice this prop’s personality the moment you hit the throttle. It grabs the water cleanly and gets you on plane fast, with a strong, confident push that feels right under your hands. Once you’re moving, it’s all about smoothness — crisp acceleration, predictable turns, and a steady ride even when the water gets a little rough.

Mercury’s Mercalloy aluminum strikes the perfect balance between toughness and flexibility. It’s strong enough to take on real-world use — like the occasional bump against floating debris — but forgiving enough to handle it without lasting damage. The included Flo-Torq Reflex Hub Kit adds another layer of protection, soaking up vibration and helping your drivetrain stay smooth and quiet through long days on the water.

Maintenance couldn’t be easier. A quick rinse after a trip and you’re good to go. The Phantom Black enamel finish isn’t just sharp-looking — it’s built to resist corrosion and hold its gloss through seasons of saltwater spray and freshwater runs alike.
