I have a 3 blade prop that I need help IDing as to manufacturer and application. The part # on it is 312200 and the size (12 1/2 X 16) is embossed on one of the blades in a raised oval/rectangle. I'm sure this is a clue as to the manufacturer. The drive part of the hub has two large ears instead of splines or a pin drive. I think this is for a mid 60's OMC 70-140 HP but not sure about that either. Many thanks to the people here who have helped ID my Pop's old boat stuff in the past!! Ahab49
