This thread includes the saga I went through with a hooked hull because of incorrectly assembled floorboards that failed to stretch out the hull fabric.
Cav plate height for Zodiac Mk4
Waaaaay, too much time and effort was focused on the height of the motor in relation to the transom. In fact, on the advice of my dealer, I had a steel plate added to my transom to raise the motor several inches and that just caused a new problem: ventilation (with the AV plate about 1 inch below the bottom of the transom).
After getting rid of that modification and just assembling the floorboards correctly, my boat runs perfectly.
