Re: Will 1974 evinrude 40 hp power head fit 1973 evinrude 40 hp?
There were some changes made in the last few years of the 40 HP models.--------------Best to check things like the crankshaft / driveshaft splines.-----------Crank is a different # ----Driveshaft is a different # also the impeller is a different # .-----Which may indicate a different driveshaft diameter.
