Michigan Wheel XHS Hub Kit 217 for Yamaha Outboard 13-Spline, 3-1/2 Inch Gearcase

The Michigan Wheel XHS Hub Kit, part number 217, is an exchangeable hub kit built for Yamaha outboards with a 13-spline, 3-1/2 inch gearcase. It is designed for use with Vortex and Apollo prop housings, giving boaters a way to replace a worn hub or keep a spare on hand without replacing the entire propeller. At the core of the kit is a Delrin cushioned sleeve that absorbs the impact and stress created when the outboard shifts gears. This sleeve is engineered to spin under significant impact, which protects the lower unit from shock loads that would otherwise transfer straight through the prop and gearcase. Because the hub is exchangeable, it lets an existing Vortex or Apollo style propeller be rebuilt with a fresh cushioning sleeve rather than requiring a full propeller purchase. This makes it a practical option both as a scheduled maintenance replacement part and as a spare kept aboard for unexpected hub failure. The kit is sized specifically for the 13-spline, 3-1/2 inch Yamaha outboard gearcase, so fitment is limited to outboards matching that spline count and gearcase diameter.

Frequently Asked Questions

What is the Michigan Wheel 217 hub kit used for? Part number 217 is an exchangeable propeller hub kit that replaces the cushioning sleeve inside a Vortex or Apollo style propeller hub, restoring shock absorption without buying a whole new propeller.

Will hub kit 217 fit my Yamaha outboard? It is sized for Yamaha outboards with a 13-spline, 3-1/2 inch gearcase; it is not a fit for other spline counts or gearcase diameters.

What prop housings work with the 217 hub kit? The kit is designed for use with Vortex and Apollo prop housings only.

What material is the cushioning sleeve made of? The sleeve in the Michigan Wheel 217 hub kit is made of Delrin, chosen for its ability to absorb shifting impact repeatedly without breaking down.

How does the hub kit protect the outboard's lower unit? The Delrin sleeve is designed to spin under significant impact, which absorbs shock from gear shifting and shifting loads before that stress can reach the lower unit.

How much does the 217 hub kit weigh? The Michigan Wheel 217 hub kit weighs 1 pound.

What are the package dimensions of part number 217? It ships in a package measuring 5 x 2.25 x 2 inches.

Can I use this kit as a spare instead of a replacement? Yes, since it is an exchangeable hub kit, boaters commonly keep the Michigan Wheel 217 on hand as a spare for their Vortex or Apollo prop housing in case the current hub fails.

Does hub kit 217 include the propeller blades? No, the 217 kit is the exchangeable hub and Delrin cushioned sleeve only, intended to be installed into an existing Vortex or Apollo prop housing.

What spline count does the 217 hub kit require? It is built for a 13-spline gearcase; installing it on a different spline count is not supported.
