Can you give us some more info?

Is this boat new to you?
Are you trimming down before taking off?
How are you using the throttles?
Are you using the tabs?
What's the condition of the tabs?
What's the hull bottom condition?
What's the condition of the props/lower units?
What's your top speed and Max RPM (what kind of load is that with)?

Anyone else think of any questions?

Have the same boat and I think the same 19 inch props

Lazy Daze sounds like you hit the big ones.

I always trim all the way down on the drives and full throttle steady up until plane then back off.
