Yanmar Heat Exchanger Problem?
Recently experienced a problem with my 1981 Hunter's Yanmar 2GM. Here's what happened.
Started engine and only got 1/2 the normal flow of water out the exhaust. Checked raw water inlet and strainer. All clear.
Noticed stream of warm water flowing out of engine compartment into bilge, but engine ran fine.
Water stopped coming out with exhaust. No exhaust either. Engine compartment got quite warm.
I suspect that the heat exchanger finally bit the dust. Your thoughts and suggestions.
Boat is back in the Bahamas, so I can't do any personal troubleshooting from here.
