Hey guys. Last weekend we slept on the hook for the first time in our new to us Mainship 31. The PO never ran the generator and I’ve had issues with it because of it. All it needed was a fuel pump and new plugs. Now she starts up and runs great. We probably ran it for 12 hrs and it ran both AC’s through the night and then one AC and one stove the next morning.
Anyway, the only thing is when an ac unit kicks on, it obviously loads the generator. It would bog under the load, then recover, but it sounded like the governor was overshooting then undershooting. It would cause the engine to surge a few times before calming down.
Before I start chasing things, I wanted to see if that’s normal or not.
It’s a gas Kohlr 7.5 genset.
I’m tbinking about running a tank of Lucas fuel injector through it. I want to do that for the mains anyway.
Since I know it’s going to come up, I did a ton of research about running the generator while sleeping and I determined ours to be safe. It’s located outside the main cabin and we have two brand new battery powered Co2 detectors that I tested right before bed.
Thanks for any help.
