Sounds reasonable. My friends 36 monk (early 90's with a Cummins) runs about that but maybe a little more top end...I think he has 210 hp or so...I've cruised with him and 7.5-8 is where we run..

Not in my experience with my Perkins. 6.7-6.9 knots cruise, no-current at about 1.8 gallons per hour. 8.0 knots max after a while. MPH maybe. After 6.9, the wake just gets bigger and you burn more fuel for every 0.1 knot/ 100 RPM.
You really have to look hard at a piling in the water to see the eddy swirls from 0.5 kt current.
