May sound stupid but try bringing a hand held GPS with you next time you test, you may have a GPS Gauge that sticks!! Had same problem on Fountain.
Does the boat ride bow down?? Do you think it is plowing??
Of course a hook will slow you down but you should see difference.

No,now with the five blade I droped from 5600 to 5200 rpm but a 25 pitch is to small always hit red line.So the five blade is getting me more speed for the rpm but I know that 400 rpm left is where all the power is.

What is the pitch of the 5 blades?
What is the pitch of the 4 blades?
speed@rpm with 5 blade?
speed@rpm with 4 blade?
What is a 620?
Do you have dyno sheets for the 620's?
What is peak torque rpm?
What is peak HP rpm?
