To that end the motor is mounted as per manufacturer instructions which placed the anti-ventilation plate 5/8" below the keel.

Which manufacturer instructions are you referring to?
Whaler or the Engine manufacturer?

The cavitation plate should be just above the water when running the boat on plane.
Any other recommendation on dry land would be just a starting point: So far above the keel or so far below the keel.
The water trail is the final test to get the height of the engine right.
