The owner of this boat told me how that, initially, it would not get on plane, even though it's powered by two, 1,500 hp supercharged big blocks and racing outdrives. The prop pitch was so great the motors to loaded up. The solution was to pipe in exhaust near the props, to make them cavitate and get the rpm up.
Boat does 160 mph at WOT!
