T&T: Fw: Exhaust

[Larry N. Brown]

Saw an article in passagemaker about a dry side exhaust system on a boat. 
The main exhaust was below water and had a clam shell over it that would act 
as a venturi and suck the cooling water and exhaust under way. There was a 
small hole just above the waterline for idle exhaust. It was keel cooled but 
did take in raw water to inject into the exhaust elbow.

Regards.
