CO2 levels while surfing

[dsthomas]

Let me first say I’m the proud new owner of a 2020 R7 Surf delivered in April of this year. A friend of mine sent me this article out of concern regarding the tragic death of a 9 year old boy from CO2 poisoning while boating on an inboard. I’ve been boating since I was a Kid and my family has always been aware of the dangers of CO2 as it relates to boating. All three of the cobalts I’ve purchased had warnings placed near the transom as well as in the owners manual. I know the forward drive has the through prop exhaust that puts the CO2 below the water line and according to the VP promotional video “well behind the surfer”. How true do you guys think that statement is? I’d think with surfing, speeds being what they are at 10-11 mph and the engine at such high rpms there would be a lot more of these kinds of deaths. Thoughts???

Here is the url to the article.

My wife just ran across that tragic death on the Cobalt facebook page. Truly one of the saddest events I have heard. I can tell you we will forever be vigilant to prevent this on our boat.

As for why this happened - I wonder if the height of the child played a part? Also like the mother stated most other similar deaths are classified as drownings, without much other investigation.

This is why a tow boat and some other owners add this down pipe. Like this. Yes it happens. Very sad. I don't think you will see this in a forward drive. It also can happen to the guests sitting in the rear seats. Some people will add a CO2 alarm. Good idea!

Sad story.. sheesh

Thoughts? Get some carbon monoxide alarms and stick them on your platform . I’ve set them off in my garage dialing in hot rods.
Let’s hope you don’t have the alarm chirping!

Dang. That’s an awful story. Wow. I can’t imagine the helplessness & guilt they must have felt. I haven’t given this the first thought. Good info.

Thanks for posting this. I saw it on fb but didn’t read the article.

I will be paying more attention when I run the captain call.

At the risk of showing my ignorance, is that because captain's call sends exhaust directly outside?

Yes. Captains call sends the exhaust, raw lake/sea water, and CO2 emissions thru the hull via exhaust pipes that are located above the water line. This above the water option is done using the flip of a switch. Sounds cooler and manly as Tim Taylor from tool time would say.

The default is for the exhaust, CO2 emissions and cooling water to exit thru the prop obviously underneath the water line. Quieter but safer. This is why many states ban a switchable exhaust.
