Underwater exhaust exit.

Instead of above water exhaust, why not exhaust completely underwater?
Advantages are less soot, less fumes, less engine exhaust smells, less CO, less air pollution for you to breathe in.
I was thinking a contoured or angled pipe type through hull, as long as you can not reverse siphon, so might have to have a small exhaust air hole above the water?
