second, verify your RPM's
third, throttle position and engine RPM are not linear. while you may be at half throttle and 5200 RPM, it may only go to 5250 with the remainder of throttle, it may go to 7000 RPM if the rev limiter is removed. this has to do with prop curves, fuel curves, hull curves and engine loading. if you truly are getting 7000 verified RPM at WOT, then we need to load the motor up a bit (prop pitch, diameter, etc.)
fourth. as requested, what is the ACTUAL WOT RPM f your current setup with the throttle mashed all the way against the throttle stops, the motor trimmed properly., and you are carrying all the gear you normally bring with you.
firth, as requested, what is the ACTUAL WOT speed as indicated by GPS
6th, as requested, what is make, model, dimensions, weight, etc. of the boat
7th, as requested, what is make, model, dimensions, material, etc. of the prop.
