I run at 2400 rpm which gives me 5-5.1 knots, 2 blade prop. Running above 3000 just causes much higher fuel consumption & stress on the engine.
I understand you'll get glazing at lower temps, but the thermostat insures its running at it's minimum temp.
The 1 time I max it out for any extended time (trying to make a bridge opening), I overheated after 5-10 mins.
I do follow the manual's advice and run the engine at high RPMs every so often to clean out the carbon deposits.
