Mercury Flo-Torq SSR Hub Kit 8M0150151

Mercury Flo-Torq SSR Hub Kit (8M0150151) is a premium OEM propeller hub system engineered to deliver smoother, quieter shifting and enhanced drivetrain protection for Mercury and Mariner outboards. Designed with advanced Soft Shift Rubber (SSR) technology, this hub kit significantly reduces propeller rattle, shift clunk, and vibration—resulting in a more refined and comfortable boating experience.

Ideal for 40hp Command Thrust through 225hp FourStroke outboards with a 1-inch propeller shaft, the Flo-Torq SSR hub kit is a direct upgrade from older Flo-Torq II systems and replaces Flo-Torq III and IV kits.
