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.

Stainless Steel 15-5: Incredible corrosion protection to complement your impossible performance.

Producing world-class Mercury propellers is no simple task

A Higher Grade of Performance
Mercury transforms aluminum and stainless steel into the highest-quality, best-performing, most-durable marine propellers in the world. Also the best-selling, no surprise. Our experience, expertise, and proprietary technologies – Flo Torq®, Mercalloy®, X7® alloy, and PVS® (Performance Vent System) – give you a true competitive advantage. For best overall boat performance, there's no substitute for a Mercury Propeller.

Flo-Torq SSR: Not to be seen or heard.
The Flo-Torq SSR utilizes proven Soft Shift Rubber technology in a quiet hub kit that will reduce the noise and vibration of Mercury's already remarkably smooth and quiet V6 engines. This SSR technology provides up to 27% peak-noise improvement at shifting events and is the perfect complement to all Mercury engines with a 1-inch propeller shaft in general purpose, non-surface-piercing applications up to 300hp. The SSR also boasts strong durability characteristics: once this hub kit is installed, it won’t be seen or heard the rest of the season.
