Hi yall! Sorry but I just got back from Texas. I need a new propeller fr my boat and saw one on eBay that looks about right for my boat. The part number on is "10 x 11 and the OMC part # is 307318". The chart that I got from here is a for Michigan prop an it gives me this "MI 012044" for a 10 x 11 prop. I have a '63 75 hp Johnson. It looks right but just a month ago I baught one on eBay and it was wrong (my fault) I did not do my homework. Can anyone help me in translating part numbers please.
