I have never seen these boat before

One suggestion on the flexing, don't inflate the pontoons all the way before strapping the frame down. 3 lbs of air and I recommend an air gauge for all inflatables. Keep in mind, his boat is aircraft aluminum, pontoons are several layers of material including kevlar and I am assuming urethane bladders. Non of the ingredients of your boat. I have run a 5 hp 4 stroke gas on mine with a 2x4 the width of the deck and 2 aluminum straps.
