Hello,I have a 1996 bayliner with a 120hp force I have a big problem with the starter or at least i think its the starter. When i go to start the engine it turns over very slow and the positive wire gets red hot so hot it melted the battery terminal and wire so i went out and got a new battery and replaced the burnt wire and the same problem. I took the plugs out and turned the engine over the starter and engine were spinning fine. put the plugs back in tried to start maybe it turned over once sounds like there not enough power to turn the flywheel also the battery was fully charged. Can it be the STARTER? Please help, Thank You
