Frequently Asked Questions
How do I know if the Turning Point 504 Hub Kit fits my engine?
Match your engine manufacturer, model, stroke or cycle, year, spline count, and gearcase size to the application chart. Do not select a hub kit by horsepower alone.
Does the Turning Point 504 Hub Kit fit every Volvo Penta SX & OMC SX Cobra and Yamaha engine?
No. Fitment is limited to the specific applications shown in the chart. Similar-horsepower engines can use different spline counts, gearcase sizes, or hub kits.
Does the hub kit need to match both the engine and propeller?
Yes. The hub kit must match the engine propeller shaft and gearcase application as well as the compatible Turning Point propeller hub system.
Is the Turning Point 504 Hub Kit interchangeable with other hub systems?
For compatible 4.25-inch and 4.75-inch gearcase applications, the Turning Point 500 Series hub system is interchangeable with Mercury Flo-Torq II, Michigan Wheel XHS, and Solas Rubex hub systems. Always confirm the complete application before ordering.
