I just bought a boat with a Johnson 3 H.P. motor. The motor model is JW-10, SN - 980600. I know a JW-10 was made from 52' to 54'. Is there any way to determine the exact year of manufacture? The engine runs pretty well but it does surge a-little bit at 3/4 throttle. Possibly because the carb is dirty or the fuel filter is not flowing properly. I was on the water yesterday and the main return spring in the recoil starter broke and I had to get towed. I don't like this Rube Goldberg recoil starter mechanisim on the 52' and want to install one from a 1960-1964. I think that if I install the 1960 flywheel and recoil starter I should be OK. Am I wrong? Will a 1960 flywheel on a 1952 change the ignition timing?
One thing for sure, I will not go out on the water with my 1960 3 H.P. or my 1952 without a screw driver and a manual pull rope again.
Thanks in advance,
Bill Albertson
