Thanks for the responses. I have posted on Planet Nautique and Correct Craft Fan forums with no response.
Let me try and describe whats going on. I've had Mastercrafts (78, 87) before this Ski Nautique, and have always used the green loop(32 off) with them. Also, I ski on 2 trick skis at 17 mph, and single trick at 19 mph . With this boat the tips of the ski dig in to the wakes, same thing at 28 off. At 22 off there is a second wake starting to form in the center, and 15 off the wakes are getting to wide, and to far apart to ski to for wake tricks.
I've noticed this same thing on other boats with 4 blade props. This is my first boat with a 4 blade prop that's why I asked.
