I found the 2003 was one of the more difficult boats to "sneak up" on the right amount of trim. Outside of having a mechanical trim gauge and an experienced driver tell you exactly where to go, Chris has the right advice. I think it is the windshield and big console that you have to overcome. At about 80 the aero starts to fight the boat from freeing up. Trim it up until you need a little wheel to balance it at about 60. Stand in the throttle. Unlike other Allison's you should feel the nose start to level back out. That is when you need to ease the trim up more. Depending on the condition of the lip on the pad, the nose will either lift or you will hear the water contact on the hull move back behind you. If you have a sensitive speedometer you can watch rpm's and mph. As long as you are gaining speed with rpm's you are good. If you lose speed and gain rpm's the prop will blow out and you will go for a dead hook ride.
