Ya it does take some time to get on plane but I run a 4 blade 28p bravo now. A 4 blade has a lot of prop in the water just wondering if you raise the x dim I might find some more speed.

EDIT: Below is with a fastech, not sr1.
The following is experiences from "RattlesnakeJake" from the Speedwake forums, shared in a mail-correspondence between us. I hope he doesn't mind me posting it here.
As far as the 2" shortie, I experienced extreme prop blowout and when I tried larger props I couldn't spin them fast enough to get max RPMs. Peak HP is @ 5400 RPM. I had the opportunity to try the speedmaster with the only cost to me being the water pickup and it didn't work out. There's another 271 in the area with a 650 HP Supercharged 502 and he's running a 1" spacer on his XR drive to get it deeper.
In theory the shortie should have given me better all round performance. But like the saying goes, "If the results disprove the theory, go with the results and get a new theory.
