It does a great job and will break into the low 70's. I haven't taken it all the way to the 6800 and with the boat balanced right, it may have 75 in it...it is pretty quick for sure. It pretty much stayed on the boat all summer last year. With it needing so little throttle to get on plane and being able to cruise at 50 barely touching the throttle it got some pretty awesome fuel economy also
Over the years I've tried many different ski props and after a few different pitched High-Fives, I settled down on an old, cheap, 23 pitch Trophy that has worked extremely well on my XB2003 with both a 225X and my current 280ROS motor.
