Turning Point Propellers 504 Hub Kit 11500400 - Volvo Penta SX & OMC SX Cobra 19-Spline Prop Shaft ('94 and Newer)

The Turning Point Propellers 504 Hub Kit (part number 11500400) is a replacement propeller hub system engineered for 19-spline prop shaft applications on Volvo Penta SX and OMC SX Cobra drives, 1994 and newer. It is not available for Volvo DuoProp or Aquamatic drives, so confirm your drive type before ordering.

This hub kit is built to protect your lower unit and propeller from the shock loads generated during shifting and sudden throttle changes. It uses corrosion-resistant brass splines paired with a nylon hub component to absorb gear shock and reduce engine and drive damage. The nylon element is designed to minimize propeller vibration and chatter for a smoother ride, while the overall hub design eliminates spun hubs and ends the hub cracking that can occur with worn or incompatible hub systems.

Finished in brass, this kit weighs 2 pounds and is intended as a direct fit for boats running the 19-spline shaft configuration used on the specified Volvo Penta and OMC drives. Because propeller hub systems are drive- and spline-specific, matching the correct spline count and drive type is essential for proper installation and performance.
