Mercury MerCruiser Flo-Torq SSR HD Hub Kit – 8M0101601

Upgrade your propeller system with the Mercury Flo-Torq SSR HD Hub Kit (8M0101601). This genuine Mercury hub kit features Soft-Shift Rubber (SSR) technology designed to reduce shift shock and minimize the harsh clunk often felt when shifting into gear. The heavy-duty (HD) hub construction provides increased durability for high-torque applications while maintaining smooth and efficient power transfer from the engine to the propeller.

Engineered for demanding marine environments, the Flo-Torq SSR HD hub system improves shifting performance, reduces drivetrain noise, and helps protect the propeller and gearcase during aggressive acceleration or heavy loads.

Function

The Flo-Torq SSR HD hub system connects the propeller to the engine’s prop shaft while absorbing shift shock. The rubber isolation sleeve softens gear engagement, reducing noise and vibration during shifting while the heavy-duty hub maintains efficient power transfer under load.

This system helps protect the propeller hub, prop shaft, and gearcase components from excessive stress during shifting and acceleration.

Important Compatibility Note

Propeller hubs vary depending on engine model, prop shaft size, gearcase type, and propeller design. Always verify compatibility using the engine serial number before ordering to ensure the correct hub kit.
