I have a problem with my port engine (2000 7.4 fresh water cooled). Up to 2000 RPM the temp stays normal but going up to 3000 RPM the temps slowly goes up to about 180 F. I had the mechanic check the hoses and change the impeller. Also I had the diver check the sea water intake which turned out to be clear from any debris. I went out today and again the temp was better but still went up at 3000 RPM. Could the heat exchanger be one of the possible causes? I normally cruise around at 2000 RPM but I would feel better if the problem gets fixed.
Thanks
