Default difference between a bravo 1 and a quicksilver

Have a 27 Kryptonite w a 28p bravo 1, 1.50:1, and a merc 500efi w the Arizona speed and marine flash. Only seeing about 5000 rpms and 72 on gps. The boat supposedly ran 81.2 WITHOUT the ASM flash and a quicksilver 14 3/4x28 @ 5250. Ideas? Thoughts? The boat pops on plane effortlessly.

What QS propeller?
Your slip is a touch high.

Your slip is about 16.5%. A touch high. (the Lab recipe could be off)

The slip would be 6% lower with the other numbers and the fact that the engine was able to pull higher R's with a tighter prop also amplifies the weirdness.

Either not as much HP now, something else has changed on the boat or............."supposedly ran" isn't fact.
