Your prop hub isn't slipping if you're only making 4400 rpm.
Physically check for slime buildup. You'd be surprised how much difference a small layer makes. More importantly find out what pitch and diameter propeller you've got. You should be doing between 5000 and 6000 rpm at wide open throttle depending on how much load is onboard so either
a) You're overpropped
b)Your hull is filthy (or worse but unlikely , damaged somewhere out of sight)
c)You've got an engine problem.
