Looking inside the engine it looks brand new on the interior. From what I understand I need a marine grade starter. How will I know what starter to put on this boat? I cant take it to the auto parts store and we dont have a marine supplier around here. I know they sell starters on Ebay, does it have to be a specific starter or does it have to match the engine?
