Just needed some advice. Looking at buying an older boat with a 1982 200hp Mercury. It says "offshore" in red letters on the cover. Was told that it was re-built about 1 year ago. I have always owned Evinrude/Johnson. Is this Mercury a good engine? Are there any known problems? I really love the boat, but not sure whether to buy or not because I guess I am "scared" of the motor. Any insight would be great. Thanks alot!
