was motoring along one day, I plugged a usb plug into my cigarette lighter receptacle, noticed a spark at the receptacle, and the engine stumbled, tried it 2 more times, when the spark would show, the engine stumbled. after reading the post on low oil alarm, Ron mentioned engine fuel lift pump, do you think this was shorting out that? I wasn't aware that it had a electrical connection, not at the boat now, going up today. Not a problem, as the usb plug was defective to initiate the spark, and I threw it away. the receptacles are fused, but before fuse blew, the engine momentarily stumbled. got us all confused on the dock. The stumble was immediate, i.e. spark, equals instant engine stumble. So if there is a short in the dc side of the boat, the engine quits? Everything is fine now but, Any ideas would be nice to hear, and yes, I should change the name of my boat :) Thanks guys, Bob
