At Mercury Marine's propeller foundry in Fond du Lac, Wisconsin, magic happens 24 hours a day. Through unmatched engineering, design, and innovation, molten metal is transformed into the highest-quality, best-performing, and best-selling marine propellers in the world. Our experience and expertise – along with proprietary technologies such as Flo Torq®, the X7 Alloy®, and PVS (Performance Vent System®) – give Mercury props a true competitive advantage.

Producing a world-renowned Mercury Marine prop takes time and skill, not to mention advanced engineering and know-how. Three dozen Mercury employees create some of the best props in the world. Every operation - from inception to completion - is centralised at Mercury's propeller manufacturing facility in Fond du Lac, Wisconsin.

A proprietary blend of 15-5 stainless steel perfectly balances strength and corrosion resistance. Perfect protection for freshwater and saltwater applications alike. Developed specifically for Mercury props.

Mercury's Flo-Torq propeller hub might just be the most important part you never see. Not only does it flex during shift changes, reducing noise and vibration. If your prop hits an underwater object, it sacrifices itself to save your lower unit. Just pop in a new hub and you're back on the water, no service call needed. The Flo-Torq hub also makes Mercury propellers compatible with most engines on the market while also providing unmatched corrosion protection.

PVS® (Performance Vent System). A Mercury-exclusive innovation for custom tuning and venting your propeller to match your engine.

Just by varying the size of the exhaust hole and controlling your engine’s rpm, you can eliminate sluggish performance or compensate for changes in load in altitude. And it’s technology that you can only get with Mercury Propellers.
