Default avoiding cavitation

Hello Everyone
Currently testing out my BJ26. Once again the system is 14 cells, hydra 120, 7xl, and a 34-37 prop currently.

I tried a proboat prop(link below) and I got about 35 mph w/temps a little on the high side. (I really should use 12 cells, 14 is turning out to be kinda high)

I then tried a carbon Y535 (miss vegas prop) and I got a ton of cavitation. The midline of the prop was about 3/16 inch above the bottom transom edge and neutral angle.

To avoid cavitating should I simply try different strut heights and angles? Should I angle/lower the strut a little bit lower w/a Y535?
