Once you get back from testing post your WOT rpm and speed. If your still running 5400 RPMs then your too low. Especially if your running a light load.

Do you have a Merc Monitor? My analog RPM gauge was off by 200 RPMs at WOT.

My best cruise speed with the 22p bravo 1 was 3800 RPM burning 7.5gph or 4.4mpg at 33mph.

EDIT:

Also your prop slip is roughly 25% at 5400 running 55mph. That's not good.

how much does your boat weigh? Hull, motor, gear, etc? Not looking for an exact number but something close would help.

Its a Merc 225 on 22ft Haynie boat not sure body weight
