Re: New to me 1977 Johnson 25hp Questions

[shane-r13]

quote FrankR:

The 1977 25hp was sort of a lower priced mixture between the “old” 25 and “new” 35hp, and yes it still had the 307949 Stainless steel Drive Pin. 1978 25hp still had the old style lower unit, but with a splined prop shaft. I’ll stick my neck out and say you could probably change the prop shaft (and prop) to a splined version, but I’ve never tried it.

Never thought of just the shaft and prop. I was thinking the whole foot would have to be changed. I’ll have to keep my eye out for those parts. I’m not
in a major rush to modify the motor. It works as it was intended. Although it is not fun running some rapids backwards in a boat trying to change the shear pin. Haha.
