Just joined and wonder if any member
could advise me how to solve an engine overheating
I have twin Yanmar
4JH2-HTE on board...the port engine
overheat when reaching 2500 RPM
(I usually run them both at 2900 witout any problem maintaining 150 F.)
Last year I have replaced the heat exchanger
. Just cleaned the intake water
filter system, replaced the salt water
pump impeller, the engine fresh water
thermostat...but still have the same problem.
Checked all hoses for obstruction as well as the salt water
Any idea of what might cause this problem ?
