I believe the greater danger is from CO being drawn into the sleeping area from the A/C air intakes on the side of the boat as opposed to CO seeping into the cabin from the engine room. Our detectors have gone off from that source on very still nights as well as during a thunderstorm when the was lots of air movement, some of it resulting in CO getting sucked into the cabin when the boat was moving around a lot. Also the diesel guys who idle their engines in the marina letting things "warm up" set off the detectors when our boat is running A/C down below, so there is a risk to diesel as well. It is less than gas, but still there. The storm event was kind of a freak occurrence, but I was surprised by how long it took for the detector to return to standby. This took perhaps 5 minutes with hatches opened to let fresh air inside. We did that in pouring down rain.
"A/C air intakes on the side of the boat"???
