The industry-preferred XHS Hub System is designed to absorb impact and stress caused by shifting gears and is designed to spin under significant impact to help protect your lower unit. For use with the Vortex and Apollo Prop Housings, the high performance XHS Hub is also designed to be interchangeable with Mercury's Flo-Torq II hub system, making it a great choice for a replacement or spare prop.
The XHS Hub Kit includes forward thrust washer, inner hub, and aft drive adapter. This kit does not include prop nut, tab washer, or cotter pin. Propeller Housings are sold separately.
