Max RPM for 3HM35F in a PSC34

Hi all,
I have a 3HM35F Yanmar with a 3 blade 16" prop. I'd like some feedback regarding the RPM people are running their engines at. Sometimes I'll run it at 2400 RPM for 4-5 hours if I'm in a hurry. Not sure if this is pushing the envelope. I've heard that running the engine at too low an rpm can cause carbon buildup. Anyone out there with a similar setup with some input?
