This is driving me nuts.

Boat is a G3 Bay 22 DLX. With the motor mounted directly to the transom, 2nd hole, P to P was 6-1/2" 21P 3-blade vs. 10" jackplate P to P at 3-1/2" 23P 4-blade.

The boat rides a lot higher in the water, but no difference in top end speed. with the motor trimmed all the way down its like I am riding on the pad at all speeds.

Can I just mount the motor back on the transom in the highest position and get more speed? Am I wasting forward momentum in lifting the boat with the jackplate? water pressure is good in both positions.
