Where are you located at? I have a Johnson 3.5 that I had rebuilt 3 years ago to use on canoe and never did. Runs like new as it should. Small with tank built in to engine. I live in the U.P of Michigan. Take 250 it. Cost me more than that to have rebuilt. They put 2 pistons in it new rings and wrist pins, rebuilt carb 2 coils and tuned up. Had running in tank last summer. Let me know if interested.
