Our genset is a Kubota–Onan 6.5Kva set. Last night, while we were asleep, it started up by itself. The seacock was closed...
We had run the set for an hour the day before, while on anchor. The front rocker switch was set to Auto, so we can start it from the helm position. We were back on the dock, on shore power at the time.
We woke up, and ran to the hatch where the genset lives, and turned on the seacock; water rushed out the exhaust. So, we will be inspecting the impeller, as a matter of course, and we have a spare on board.
I do not know how the helm switch to Start/Stop is wired, but with the set on Auto (meaning remote start; the other positions of the switch are Run and Off)—is it possible that our shore power failed momentarily, and that started the generator? This has never happened in the three years we have owned the vessel. And if auto-starting is a feature of this setup, we will be sure to leave the rocker switch on Off in future.
