Wind and pie move my boat.
I'm getting an alarm on my engine panel that says cw overheat after running for about a hour at 2500 RPM . If I let it idle for about 10 minutes the alarm goes off , but resumes if I continue at 2500 RPM . Yesterday I nursed her in at 1500 RPM with no resultant alarm . Could someone point me in the right direction for what I should be checking to diagnose this issue ???
