I feel like the problem is on the raw water side, a friend of mine at the marina who is a very good mechanic feels it is on the heat exchanger side. After the engine overheats the relief valve at the hot water heater lets go and I think that is why he feels it is on that side. When I bought the boat in 07 the heat exchanger was hooked back to itself with no fluid in it and did not get hot. I fixed that when I put the new hot water heater in. I checked the thru hull, the strainer and have raw water flow when the cover is off the pump. The impeller is turning, I do not have good water flow out of the exhaust and that is where I left off. I have not done anything with the heat exchanger yet. I appreciate the advice as I am trying to determine were to go next.
