One question of outboard engine

Not even close to the same risk. CO is hugely toxic gas produced by incomplete combustion.
It has no scent, is neutrally buoyant in air and our hemoglobin has a 250 times greater affinity for it than oxygen...

Besides, why are you challenging someone's likes and dislikes?
The posters dislikes are for a reason not known to you, nor are they relevant.

I was pointing out that CO in the accommodation is no risk in well designed and properly vented engine compartment, which is why i used the car anology.

He can dislike outboard motor wells all he likes and for any reason he likes, including the fear of CO in the accommodation, I am just pointing out to others that his fears need not apply to everyone or to every installation.

I dont much care for schooners, no one is going to convince me to own one, but I am not offended by an alternative opinion.

 

Read his post. His fear of CO in the accommodation. Only applicable in a bad set up, as such, relevant as it can be avoided.

 

Very good gas to oil proportions.

 

Most of the vessels I’ve seen utilize a doghouse or some sort of enclosure. Here in Minnesota, we have Sophie’s Law after a 7 year old fell ill from CO and her Mom laid her in the cuddy where fumes were even worse from an exhaust leak. They left the cuddy door open so the Mom could listen for her which created suction for the exhaust leak to travel through the bilge. Any sleeping areas require them here after the girl died from CO while the fanily boated about the lake.

For the boat with the engine inside; I’d probably want the alarm at least.

 

It is these tragic accidents that lead to better design/regulation. A CO/smoke/gas alarm should be on all boats with cooking facilities or explosive fuels on board.

 

Yeah, my catamaran is category A. its transom is at a sharp angle to water plane，so that it is difficult to set outboard engines normally. My boss told me we can install outboards front of transom with a likely "moonpool" structure. water sealing becomes a big problem.

 

it is same with me, i hate abnormal designs. I do not think somebody buyer will like these.

 

yes , that's why so called "outboard engine"

 

in case of these, I set a separate well to install outboard, but half of the well height is under the water line. It is madding me ./
