Fellas new here, looking for some knowledge from those who know Props, and step hulls. I am going to add a link to Q&A Posted on OSO. I could really use some conformation or other advice. Appreciate all the help.

2000 ZX with the 377's. I have a set of 3bl 25p lab mirage boat runs 72 gps 5000 rpm.
Also have a set of 4bl 26p lab Bravo I 74 gps 5000 rpm.

What am I doing wrong? Thought this should be an 82 mph boat with the twin step hull? Fuel levels were approx half. 1-4 persons did not matter.

2nd question. I have been getting a lot of cavitation when getting to plane. I have backed up on the K planes and has since helped. Thanks for any and all help.
