Boomerang, thank you very much for your reply! So in essences, this is an AC source selector panel. I assume outlet means shore power. I'll have to see if the inverter runs through this panel. The labeling is a little Spartan.
The other question with which you may be able to shed some light is that of the tank or can labelled Onan under the stern deck. It was not removed with the genset. It has a 2 inch rubber hose leading toward the area where the genset used to be located which is disconnected and not capped. Too big for a fuel line. Do you think it is an exhaust? Should I remove It? For additional storage space?
Thank you so much again for your response!
