I have read with only mild interest the threads that have mentioned CO exposure on the swim deck while idling the boat. I will state I may have allowed people to remain seated on the swim deck while repositioning the boat due to the wind getting us close to the shoreline. Someone recently posted a link to a cheap CO monitor so I thought I would investigate myself. The attached word document has the results but I will say I was seeing more than 400 ppm while idleing the boat in forward going with the wind. Even going into the wind I was seeing above 100 ppm.
Guys this is kinda serious. If you are allowing people to stay on the swim platform with the engines running they are inhaling CO. Granted it will take hours of exposure to get to a life threatening situation. But after seeing what I saw today, I will be altering some of my practices.
Just wanted to give some firm data so you can be a responible boat captain.
UPDATE ON SURFING
I took the meter out with me while surfing. I used a tupperwear container to provide a vacuum and slow down the air flow like @Murf'n'surf suggested. Nearly all the time, no matter the direction, I was reading 000 ppm. Only for a brief time did I see numbers bouncing in the 010-013 range. For one moment I saw a 016 ppm. I think it is safe to say that exposure while surfing is a non issue. (my daughters big belly is my third grandbaby. He went surfing with mom today.)
