Jim,
Thanks. I will be having 3 people in the boat most of the time. A guy I know has a 11' x 54" with a 582, 60" whirlwind, and it does excellent. I need something a little quieter than most airboats b/c I am running near houses to get to the duck hunting hole. i dont have to go through much deep water, it is mainly 2-3" deep crossing over some mud, but it even has a water sheen over it.
