The spray could be from your fish finder transducer.

Max speed should occur just before the prop ventilates (Starts to slip and engine revs). This is the point of most thrust and least resistance.

Is it electric/hydraulic, or manual.

It should have adjustment bolts to raise or lower it.

Depends on the V shape of your boat, but a rule of thumb is, the anti-cavitation plate should be even with the bottom of the transom.
