Per tglee's message, there are a lot of variables that can affect performance... in the scenario I noted above, it was fairly early in the morning and the water was still quite calm, winds were light, and it was just myself and a buddy in the boat (very light load).... To the best of my knowledge, my prop is stock, just a plain old aluminum prop... not sure the pitch. I had just installed some SmartTabs and was "dialing" them in....
On a side note, I know there has been a lot of discussion about the SmartTabs on this forum but I must say, they have made an amazing difference on my '96 1900 SR2. She planes much quicker, virtually no "chine walking" and she corners like she is on rails now.
