So i threw a belt on the water the other day. While installing the new belt the casing snaped while tighting the bolt. So i made my way back to boat ramp. Alternator is fine but i dont think the bolt will hold on rough water. Im looking for my best option (rebuild, new upgrade). I have a 89 comp running 2 amps and base tube, 2 batteries. I am fixing to go get pictures and values off the items. Just wanted to get thread started.
