My 2006 hull with stock 496HO, 26 pitch 4 blade Bravo I prop and 1.50 XR drive runs exactly 70 at 5.100 RPM.
81 with the same hull and drive, and just 100 hp more, seems a fantastic result, and also with an incredibly low prop slip.
Am I missing any other trick that you're using on your boat?

A "new" 525efi is really close to around 550HP from what I have seen, also I am sure his RPMs are around 5350 much more than a 496ho shoulds spin.
