Hi, I am looking at getting a 91 Evinrude Spitfire 150hp and was wondering if I should run or is it worth getting? The guy selling it says that it will rev up in neutral but when you go into forward gear it tops out at 40mph and at 3500rpm. I am asumming that it is the rings? I am not worrried about have to rebuild the motor just wondering if it is worth buying the motor? He is wanting $500 .. pretty cheap investment hopefully. I have not done a compression check on it yet.

Thanks, Justin
