Boat propeller, 15 x 17 pitch 3 blade aluminum for Mercruiser Alpha One drive may fit others drives. Like new condition. Was spare prop, but I sold the boat long ago. This is an aftermarket prop, not OEM Mercruiser, maybe a Michigan Wheel, not sure. I dont have the hub kit, but should work with any Alpha One hub hardware. Perfect for a spare. $50. Located in Sturgeon Bay. Call or text Pete.
