Mercury launches new prop hub system

Sep 15, 2015 by Guest Writer

Wisconsin-based Mercury Marine, manufacturer of marine propulsion and technology, has introduced Flo-Torq SSR HD, a propeller hub system designed to improve shift noise and vibration on high-horsepower outboards that use a heavy-duty 1.25-inch propeller shaft.

SSR stands for Soft Shift Rubber, which adds a bonded rubber sleeve to one end of the hub, absorbing shock and vibration.

As soon as the propeller is under load, the stainless steel end of the hub engages the core of the propeller, creating a solid hub that can transfer the power generated by today’s four-stroke outboards.
