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.
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.
Yes. The hub kit must match the engine propeller shaft and gearcase application as well as the compatible Turning Point propeller hub system.
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.
