this one will be a simple fix, but it will take a heavy hammer to get it done.
You most likely don't have a hook in the hull..what you have is the tail edge of the hull has not been peened up as much at the transom, thus the motor has less ability to raise the bow.
Here is what you can do: take a heavy hammer to the trailing edge of the hull, behind the rivets, right at the transom. Peen the trailing edge up to tighten the joint (you will most likely push out a little silicone), which will help you trim the boat better.
Go slowly, though, and do most of your peening about 8 inches and further from the centerline of the boat. If you get a little too happy here you may create some excess water coming up between the motor and boat, kicking back into the boat.
If you happen to go too far and find the boat wants to porpoise right away, you can take a mason's chisel (4 inches wide) and wedge the gap back open a bit. So long as you don't go crazy, you can do this with some really positive results.
I am curious, though, of your rpms with the 19 and 17 pitch props. Being a 4 stroke motor, you should be reaching (I believe) 6000 rpms with your gear ratio of 2:1 if memory serves me correctly.
