Default Re: yamaha OX66 250 hp

I have a 200 EFI Merc and noticed the same thing - my cruise 3400/3600 - at 4000 the motor pitch changes obviously and without really knowing I'm sure the consumption as well. At modest cruise 3400 -3800 I get 2 to 2.5 mpg in flat water, that I have checked well. I would expect similar for that motor.
