This is an interesting thread. Set back plates were very common with fiberglass boat for a number of years before the boat manufacturers began to design the hulls with integral set back.
I don't see what the problem is. The purpose is to get the motor off the transom, allow it to be raised and lowered for maximum efficiency. Most Bass and Walleye boats today use hydraulic jack plates that allow the motor to be raised and lowered. These Jack plates used to be a set back of 4-6 inches in addition to the up and down.
Look at the transom of any fiberglass rig and you will see that it tapers back so the motor is set back about 8-12 inches off the flat transom. Jack plates still give the up and down adjustment, but the manufacturer has built the set back into the hull.
My Skeeter 1850DV has a flat transom with the motor mounted pretty much down on the transom, no set back, no up and down adjustment. The original owner and dealer did not know anything about rigging a boat, or the owner did not want to spend the bucks on a hydraulic jack plate. He chose instead to put a "whale tail" on the motor to get the lift he needed to plane the boat. I have not put one on as I have not wanted to drill more holes in the transom. I do not get the top end speed I should and the boat tends to porpoise if I trim out to much. I still think about it, but have not done anything about it.
