Slow Down.

Sounds like chine walk. Setup and weight distribution can make a difference. You can trim down a little to stop it or you can learn to balance the boat on the pad with steering input. Just don't try to drive straight through it. It can get out of control.

Chine walk.  Prevent it with steering input.  Important note, do not lift when chine walk starts.  Trim down until it stops, then lift.  If you just lift, the bow may grab at a weird angle, causing some bad things to happen.

Lame! LOL.

Check your steering slack, there shouldn't any engine movement without steering movement. Trim down to lose speed and turn slightly to settle the pad surface. Anything over 70 mph it gets touchy and takes some driving skill.
