 Help!!! Cavitation Adjustment
I have a 31 vanguard go-devil on a 20 foot go-devil boat. I just bought the rig from a guy who used it for mostly bowfishing. I just took it out for the first time and the SOB keeps popping out the water. Should i bend the Cavitation plate up or down to keep it in the water.. Help me please

 Help!!! Cavitation Adjustment
Bend it up just a little and go test run it, you want it to run right at the surface of the water, try not to over bend it as it will pull the cavitation plate down

 Re: Help!!! Cavitation Adjustment
Just the last inch that protrudes past the pieces that are bent down on the sides.

 Re: Help!!! Cavitation Adjustment
The peice that sticks out on the end, bend it up 1/8" a time till it stops.

 Re: Help!!! Cavitation Adjustment
What if the tiller handle starts to pull a little to the right? Used to, I could let go and it would stay straight in the water, now it pulls to the right, and tires your arm out after a while.. What should I do?

Shift weight around. It doesn't take much.
