Turning Point 509 Interchangeable Propeller Hub Kit

The Turning Point 509 installation hub is one of the brand’s interchangeable propeller hub configurations. It combines an engine-side spline connection with an outer interface made for compatible propeller housings. The arrangement is intended to ease future propeller changes while reducing the shock that can pass into the drive during engagement. Turning Point identifies brass splines among the corrosion-resistant components used in this hub family.

A resilient hub system can help control gear chatter and vibration that otherwise travel through the propeller connection. Turning Point references compatibility with selected Michigan Wheel XHS and Mercury Flo-Torq interchangeable propeller systems, but the required kit number is determined by the actual engine and propeller combination. Model 509 must therefore be checked against the engine shaft details rather than selected by appearance. The same brand may require a different hub for a different shaft or gearcase.

Choose this kit when the Turning Point application chart specifically calls for hub 509. Compare the propeller housing and existing shaft arrangement before removing the original hardware. Use the supplied installation procedure to preserve proper seating and fastening. Additional options are available in our hull protection and propeller equipment category.
