Well 68 mph is a pretty nice speed. With your set up the estimated speed in the speed calculator is 91 mph! Quite frankly a Pursuit is not going to do that! You are also pulling over 6000 watts, which is over the manufacturers designed capacity, so I would suggest that perhaps the motor has lost efficency somewhere. In fact changing that one variable in the speed calc from 90% to 70% puts the estimated speed at 71 mph, so in that may lie your answer. It could be that the prop is inefficient at high rpm on a mono, whereas with a cat hull it would not be and would do the business.
