Turning Point Propellers 11500100 501 Hustler Hub Kit for MerCruiser Alpha One and Bravo One Drives (1983 and Newer)

The Turning Point Propellers 11500100 is a 501 Hustler Hub Kit engineered to protect the drivetrain of MerCruiser Alpha One and Bravo One drives (1983 and newer) from shock loading and vibration. The hub kit fits between the propeller and the propeller shaft, absorbing the sudden torque spikes that occur during gear engagement, shifting, and sharp throttle changes. By cushioning these impacts, it reduces gear shock and helps prevent damage to the engine and drive components over time.

Vibration and chatter at the propeller are also minimized, giving a smoother ride and reducing wear on shaft bearings and seals. The kit is built with corrosion resistant brass splines and a nylon body, a combination that stands up to constant exposure to saltwater and freshwater environments while maintaining a reliable, low-slip connection between the propeller and shaft. This construction is designed to eliminate spun hubs, a common failure mode where the inner hub spins freely inside the propeller barrel and causes loss of thrust, and it also helps end hub cracking that can occur with lower-quality hub systems.

This hub kit is sized as a 501 and is designed specifically for MerCruiser Alpha One and Bravo One drives, 1983 and newer. It is finished in black and supplied as a single unit for one propeller installation.
