some of you may know my boat broke down 3 weeks ago, 2 weeks I dropped it off at the dealer because I was at a lost on what was wrong. So the dealer calls me and says they put a scope in it and it looks nasty, rebuild motor with everything 4000 dollars, ummmm no lol. So I am going to tear it aprt tuesday here is what happened and would like a few ideas of where to start or what it could be.....please
boat ran fine for 2 mins, star motor just died, restarted once and sounded very very rough like one piston was not in sync. The 5amp fuses blows everytime, now the circuit board has 2 5amp fuses and only 1 of them blows. When I remove the negative cable from the star motor it does not blow but when then cable is close to the post it will arc and blow the fuse. The spark plug when removed was light grey almost like an overheated plug and there was metal dust on it. so is there something that could break internally that would cause a short like this?
