I have a 2001 282 with f250's I'm pretty close to spec also....finally. I had a issue where I wasn't running propper wot numbers. finally gave up guessing and called Grady. Told me to raise the motors to the 2nd hole and bingo I'm on par with the performance reports put out for the boat and motors. My scuppers are above the water line by about an inch or so pending full tank or empty.
