Just wondering if my johnson has a wrong motor cover or is this how it came from the factory. Its a 1983 35hp johnson long shaft converted to short, and the cover says 30hp. The guy i purchase it from owns a outboard shop. He says these 30 and 35hp johnsons are identical.. I want to switch out that cover to the correct one if there's any 35hp cover for this particular model. So what do you guys think, wrong cover, or his he right?
