redogman67 Posted March 31, 2009 Share Posted March 31, 2009 I have a 1974 evinrude 25 hp manual start that I think has a bad lower unit because it slips all the time and feels like I am hitting something. Anyways I got a free Johnson I think its a 1970. Model # 20r-70e. Its a 20 hp that doesn't run. So will the lower unit from the johnson bolt right up to my evinrude. If it will is it hard to do?

boatfixer Posted April 1, 2009 Share Posted April 1, 2009 Basically the answer is yes. Are they both long shafts? If not, it's still possible but you would have to swap drive shaft, water tube, shift shaft connector and adapter housing. really not a big deal though.
