Title pretty much asks the question. I have a blown up 1985 90 hp Evinrude E90TLCOS, and I have come across a 1975 135 with a bad lower unit 135ESL75E, the first E might be something else, I'm waiting for a better picture. Since the 90 has tilt and trim I think the best fix would be to pull the 135 powerhead off and move it to the newer motor. The question is will it move over? I would probably move the newer ignition system too if it will go.
