"This is a 2004 AD41 turbo 350
"This is a 2004 AD41 turbo 350 hrs. that was running perfect until about 3 weeks ago.
I've been experincing an overheat problem when running above 2000 rpm. I've changed the water pump impeller and thermostats, changed to new belts, added new anti freeze to adjust the level, checked and cleaned the sea water screen. There are no leaks in the system and as best I can tell no hoses are collasping under power. The heat exchanger has not been tested in any way, but with such low hours I didn't feel it is suspect.
When I back off the R's the temperture drops and I can run 1500 to 2000 all day long.
Does anyone have any other ideas or experienced a similar problem and what was the fix?
Thanks for your response in advance."
