Product details:

Flo-TorQ II Modular Propellers are designed to let you easily switch props, change pitch, change from aluminum to stainless, or replace a bent propeller. Just remove the old prop housing and slip on a new one. If you happen to run into an underwater obstruction, the Delrin sleeve of the Flo-TorQ II System is designed to break awayfollowing impact, ensuring that damage to the engine, engine drive, and propeller is kept to a minimum. Then you can simply change out the hub kit for much less than it costs to replace a one-piece propeller. Flo TorQ II Hubs are also interchangeable with Michigan Wheel XHS Hub Kits. This is the Flo-TorQ II Hub Kit only. Propeller housings are sold separately.For use with MM 135+ HP outboards and (No Suggestions) Alpha and Bravo One sterndrives
