Try some 3 blade lab mirage plus in the 27p range. Turn them in and you may be able to get to 5100 rpm which will give you 78 mph. That is about all you will get with 525sc in that boat. Do you have extensions boxes? Boxes with a 2 1/2" rasied X dimension will give you 2 mph. You will have to go to 4 blades with the raised drives.
I am running 1.36 drives with 525sc's that have been upgraded to the B&M 250's with additional cam and head work (600hp). Turning lab 26p bravo 1's in at 5300 rpm. The boat has boxes with rasied drives and blueprinted bottom. Runs an honest 85 to 86mph on average.

Use a 10% slip which is close for that hull.
Good luck.
