Another Alarm Question

[Rocky5514]

I have a 2008 Searay Amberjack 29 and the last couple of times I have been cruising after a couple of hours or if I am in rough water my cabin CO2 monitor goes off. I unplug it and then replug it in and it seems fine. I read that they are to be replaced every 5 yrs. if not they will beep until changed....any ideas what it could be?,,,,,or should I just replace it and go from there?

The beep pattern will tell you the issue - compare to the manual.

But it could also be because you are actually getting CO down there - in other words, it's doing it's job. Google and/or search on this site about the station wagon effect. It's been talked about many times, but in a nutshell, under certain conditions CO can be drawn back into the cockpit/cabin. It's a combination of how your camper canvas is being used and lack of forward venting.
