Teja,
Maybe I've misinterpreted your meaning here, but I just wanted to add that even with a gasoline engine, the purpose of the blower is not to evacuate CO. With gas engines, the blowers are used to vacate any potentially explosive gasoline fumes from the inner confines of the boat.
If there is a leak in the exhaust system that is allowing CO into the cabin or engine compartment, I would not under any circumstances rely on a blower as a remedy. But you're right, CO is much less of a worry with diesel engines.
I think the reason they add the blower on these diesel-powered boats is simply to evacuate heat and odors from the engine compartment. As Faster mentioned, it would be nice if that blower fan would stay on for 5-10 minutes after engine shut down.
