2007 3600 Open QSB 5.9 380 hp Propeller and Engine Performance Test today
#2
Not an expert but I agree with you.  The RPMs could be limited by a governor and thus you get to the max RPMs without 100% load and not overrevving.  I think this would explain the fuel burn differences as well. Try those 27 pitch once repaired and keep the 26s for spares.  Good luck.
