Michigan Wheel Michigan Match propellers are among the finest propellers available, made from superior materials and by superior craftsmen. In the Michigan Match prop, you'll find high-strength, fine-grade alloys that ensure longer prop life. Michigan Match props have a high gloss black powder coat finish that minimizes speed loss from drag and protects the aluminum prop. Cushioned rubber hub absorbs impact and reduces the potential for lower unit damage. IF THE THIRD NUMBER IN THE PART IS A "1", THE PROPELLER IS CUPPED. PLEASE BE SURE TO CHECK TO SEE IF YOU ARE CURRENTLY RUNNING A CUPPED PROPELLER IN ORDER TO MATCH THE RPM'S. Michigan Match propellers are backed by Michigan Wheel's limited lifetime warranty. Michigan Match props have a pressed in hub, so you do not need the XHS Hub Kit with this propeller. Be sure to try out our Propeller Guide to find the right propeller for your engine.
