I have 2000 Glastron with a 4.3 Volvo Penta engine. It is a carbureted engine so I believe that makes it a GL model. The engine serial number is 4012007655. My issue is the engine will shut off at times, like someone turned the key off. This has happened while idling and while running on plane at 3,000 RPM. The longer the engine runs continuously (20 minutes +) seems to make this happen more frequently. That being said another common time for the shut off is idling as the engine is warming up. After every shut off, it starts right back up again usually with little trouble and runs well. I have tried new fuel with seafoam which has not made a difference. I have to believe this is something simple as it runs well other than the random shut downs, but I?m not sure where to start. One thing I do notice when it randomly shuts down is that the starting alert (beep beep) does not happen, for instance if the kill switch was pulled. My next step at the advice of a marina tech is to pull and clean all the electrical connections. It seems unlikely that this is some sort of overheated electrical part as it starts right up again. But I?m no mechanic?
