Placement is on the non-surf side.
In the water at the waterline. Not too low or high.
Decals might cause it to fall off sometime.
I have used it far back on the hull.

Try 100% surf and 75% non-site for ballast lockers.
Some run it 100/100.

Adjust as needed. People sitting. Front weight. Ballast locker weight.

Speed 10.5 +/-
Test different speeds
