Re: 15hp Johnson short shaft
I'm not sure on the rude but I think late 80's/early 90's. Might be too much of an age difference.
I have no clue on the internals of the rude lower. I received it as a "parts" motor when I bought my boat in '08. The rude's powerhead is bad but was told everything else should be fine. My boat has an '84 15 hp Johnson on it. I have used some small things off of the rude but not a lot.
If I get the chance tonight, I'll get the serial number off of it and look up the year.
