Top speed oceanrunner 200

[Morgan320i]

I have a 97 Wellcraft 210 Coastal it weighs and dry at 3200lbs it holds 100 gallons i usually run about 3/4 a tank, i have a 15x17 prop, i run 28-30mph at 4k rpm, and wot i get to 39.6 or so per my lowrance gps at 5500-5600 rpm, i expected a higher max, but is this about right for my prop and setup, 30mph at 4k which is what i have read to be a good fuel burning rpm, but i thought there would be more

My 21 foot Dual Console has a 1998 150 Johnson. I get nearly 40MPH out of her, at max throttle. I run a 17P prop also. I would think you would get a bit more speed, but, some boats are not designed to go faster. My boat has great power and acceleration, but propping up/trimming up/raising the motor up does not give extra speed, for some reason.

Mine is the same I don't get any extra speed from trimming it runs like a top I just figured my speed would be close to 45
