The only thing mechanically wrong with my boat is the speedometer does not work. The previous owner said that there was a peice on the back of the boat that got broke. He did show it to me. It was like a plate that holds the little wheel thingy and it had a wire on it. He said the wire was broke and the new one would need hooked up. He said he had it ordered and would mail it to me. I am getting tired of waiting so I decided to try to find these parts myself. I could not find them on the diagrams on the parts link here. Can anyone help?
