Thousands of dealers across the country and around the world sell Michigan Wheel props, offering unrivaled inventory of replacement stock, ready for immediate delivery. Every prop is thoroughly inspected to make certain it meets rigid quality standards. This 100 year commitment to quality and performance is the reason more boat owners pick a Michigan Wheel replacement propeller than all other brands combined. The highest-grade metals are used on Michigan Match propellers - high quality aluminum and tough 15-5 stainless steel alloy. The tighter grain and compact molecular structure of the metal in Michigan Match props make them far less brittle, far less likely to break. It also makes them easily repairable by a qualified repair facility.
