I had a Yamaha 200 on a 22' Century that I averaged 1.75-2. I usually ran as fast as conditions allowed without being in WOT.(I do recall always being over 4100 - 4600, I think.
That most be a great motor, if it is averaging those numbers for most. The other good thing is mine didn't even smoke or smell fumey like some and wasn't noisy in my opinion. (If I would have had 2 of them, I would have kept the boat)
