I'm looking at a boat with a 1986 Evinrude 50 on it that looks good and seller says it is one of the best motors 'Rude ever made. He wants $600 for motor or will sell without. Anyone have an opinion ot that motor? I know he has taken good care of it as he does with all his stuff. Bought a 1999 Johnson 9.9 from him a couple of years ago and you couldn't tell it from brand new.
