Running the Honda's

[a64pilot]

Came off of a couple of weeks of cruising in really hot weather, as such I wanted to run my little Honda's in anchorages where I was by myself so we could AC the boat
I've got one of these at work and brought it with me Scott Mini-SA Carbon Monoxide (CO) :: Argus-HAZCO
Anyway no matter where on the boat I put the Gen's, even when there was a good breeze off of the bow, I would get CO in the cabin, always more than 10PPM, sometimes as high as 50PPM, near as I can tell 100PPM is the threshold where it becomes deadly. I never did smell the exhaust, I know CO is odorless, but the rest of the exhaust isn't. I had always assumed if I were getting CO in the boat I could smell a little bit of exhaust. I don't smoke and have a pretty good sense of smell I thought
The only place I could put them to get to 0 PPM of CO was in the dinghy with it lowered down near or in the water. Another plus was with them in the dinghy, you couldn't hear them in the boat with the boat closed up and the AC on.

Anyway CO poisoning is cumulative, so be careful with these things
