I get an overheating alarm on my 1994 Yanmar 3jh2e when I push it over 3000 rpm or when I reduce rpm to low after running the engine for a period of time.
I think the elbow is original. I boiled it out in acid about 150 hours ago. The engine has 750 hours now. Water flows out of the exhaust, but I can't say if it is enough.
Question, would you start the troubleshooting by replacing the elbow?
Thanks,
Mike
