Hello,
I have a 1997 Rinker with a Mercruiser 4.3 the other day I started the boat on the muffs to prepare to winterize, it was running for about 10 - 15 min (I was waiting for the thermostat to open) when the engine died, acted like it ran out of gas. I tried restarting and it would start and then stall. After each time it would stall I could hear the fuel pump running. After about 4 or 5 times or trying to restart I went to turn the key and the 20A fuse near the battery blew. I verified that all connections were tight, I even changed to another good battery and when I turn the key to start I heard the starter click like it does to engage, but the fuse blew. So I proceeded to disconnect the alternator and fuel pump and oil pressure sender, and elec choke, one at a time to rule out individual components. Each time I would try to start the fuse would blow. So then I tried jumping the starter at the both solenoids primary (at the starter) and secondary (near the circuit breaker) I get spark, but starter doesnt do anything. I then removed the starter and went to auto parts store, it tested good, but made a loud growling sound. (tested it like 5 times). I also rotated the motor over at the flywheel without starter in place, it turned over fine! I then reinstalled starter in boat, hit the key it the motor turned over no problem. When I shut the key off and tried to crank it over again, nothing happened. Fuse DID NOT blow this time, but all dash lights dim and everything loses power. I'm thinking even though the starter tested good, that under a load it is NO GOOD???? but honestly at this point I'm not sure where to look.
I also cant find any broken or chaffed wires
