Well this is what i came up with after a day of thinking. I’ll be perfectly honest here. The engines are obviously modded but i’m pretty sure this is one of the fastest boats without a physics mod. You wanna start with the trim all the way down at about 19% throttle like in a real boat otherwise you’ll flip foreward. Wait for the speed to steady out and very carefully adjust the trim so it barely skims the top of the water. Too much trim and you’ll just take off. Too little and you’ll flip foreward VERY EASILY Then take the throttle slowly to 50%. Do the same type of adjustments to the trim like the first stage. When the acceleration starts to even out and you’ve adjusted the trim, use 70% throttle, and then in 10% increments from there on. Fastest i’ve had it before it flipped was around 1800mph
