I'm a new boat owner and just purchased a 1985 Sea Ray 170 with a MerCruiser 3.0L engine. Went out today and started the engine and let it warm up a bit before shoving off. After about 5 minutes of idling smoothly everything suddenly shut down. Tried restart it but it was dead as a door nail. None of the accessories, blower, bilge, nav lights etc worked. However, when I tried the trim adjustment, I had power to that.
Any suggestions?
