Post subject:  Cavitation plate or Adjustment screw?

Running a 20hp GDLT -

I'm supposed to be seeing the cavitation plate operating 2-3 inches below the surface at full throttle - however, its getting pulled WAY lower than that - almost 12-14 inches.

My cavitation plate has the dealer lift to it (up) and my adjustment screw I haven't touched because I've had to grind out of a few predicaments in the past.

Simple solution I would think is to bend the cavitation plate downwards...

Its possible that all i need to do is raise the adjustment screw on the transom (that limits the drop/rise to the motor while in the water) but I was under the impression that you don't want the adjustment screw to be touching the motor at full throttle - while still allowing room to dig in when required.

Advice?
