When I last posted I had tighted up the neg ground and that worked (also replaced battery and solenoid). But now it won't start again. I shorted the starter with a jump box and it didn't turn the flywheel. Also I switched starters with the starboard one and that worked. This is getting frustrating the trouble shooting combined with intermittant successes. Anyway can an automotive starter place rebuild (or a marine place) these or should I just by a new one?
