Michigan Wheel 222 Delrin Prop Hub Kit - Nissan/Tohatsu, Mercury/Mariner/Sea Ray 10-Spline 3 Inch Gearcase

The Michigan Wheel 222 is a Delrin cushioned hub kit built for the Xchangeable Hub Series (XHS) propeller system, designed for use with Vortex and Apollo prop housings. The Delrin cushion sleeve absorbs the impact and stress created during gear shifting, and it is engineered to spin under significant impact loads to protect the lower unit's gearcase from damage. This exchangeable hub design lets boat owners rebuild a worn prop hub rather than replace the entire propeller, making the 222 a practical choice for a replacement hub or as a spare kept on board.

The kit is built for 10-spline, 3 inch gearcases and fits Nissan/Tohatsu outboards as well as Mercury, Mariner, and Sea Ray outboards using this same spline and gearcase size. The Mercury/Mariner application corresponds to 25-30 HP outboards. Each kit includes the Delrin cushion hub itself along with a forward thrust washer and aft drive adapter needed to complete the hub rebuild.
