I have a 1967 18hp Evinrude fastwin model 18702R that I want to buy parts for. In particular, water pump parts and the seals, gaskets and O-rings for the gear case, breaker points and condensors. Unfortunately all of the parts list on the online stores only go back to 1968. I believe the parts listed for the 1968 18hp Evinrude are the same parts as used in the 1967, but I am not sure and I do not want to do any damage by installing parts that are not intended for this motor. I'm sure if I could get a hold of an old timer in the parts department he would be able to set me straight...Any opinions or suggestions?
