We experienced an issue last year when our battery bank died and we had to run off our generator for a night to charge the batteries. The generator ran fine, smells a little rich, but the exhaust kept filtering into the cabin and setting off our CO2 alarm. It is a wet exhaust, but there is still a decent amount of fumes that come with it and into the air.
Does anyone have any tips for controlling it? I would also like to not offend other boaters with it if possible.
