So this is my first boat with a hydraulic jack plate. its a 6" atlas. My first boat with a 250 and first boat fast enough to chinewalk.

As far and starting off and trimming the boat to pad whats the best way to do this. I have basically found my sweet spot of about 2.5" on my skeeter FX-20 and trim the using motor trim and leave the jackplate alone from there. Once on plane I have played with it a little but it seems to want to chine walk any way I move from 2.5"

 

How do you guys operate your boats with yours?

Trimmed out and WOT and a decent load turning about 5500 RPM on a 250 SHO with a 3 blade 25P prop I can run about 72MPH but she seems to want to chine walk anything past this. Any thoughts? 

I have an Atlas 8" and frankly mine runs great all the way down so I rarely raise it under way.  Maybe an inch if I am light and in a "race".  I use mine to jack up and go shallow, and occasionally jump up on plane in shallow water then jack it down as it gets up on plane.
