" I'm looking for, what I want to call, Exhaust check valves. 1972 Chris Craft 350Q. These are at the top of exhaust elbow's that fresh water hoses go to from the heat exchanger.
The housing for these have three bolt holes. The "check valves" are rusted shut on the Port engine and Starboard engine will not close causing exhaust to flow back into the fresh water system (heat exchanger).

Thanks
