This is a great thread, have often wondered about it…Tried to look up part numbers on ME.com, but they don’t have breakdowns for these engines…I was under the impression that the gear ratios were the same, OMC just put a smaller pitch prop on the 10hp. Hopefully someone with access to the 1957 parts break downs for these engines can clear this up….
