I could be mistaken, but, I was told that there is a BravoIII XR drive that used on some large performance cruisers w/diesel or 525 power.

I'd go with the 29 Activator or 28 Active Thunder

The Activator is claiming speeds of mid 80's with a Merc 525 .

Most hulls won't carry the nose without positive trim so the drive doesn't work well on them but on cats, the air carries the bow and the drive works real well. Only failure so far was a twisted off vertical shaft and that was due to loading while planing. Airating the drive fixed that problem. I installed a neutral safety switch bypass switch so I can start in gear but with the efi, it will shift into and out of gear with no real problems.
The drive was ahead of its time. A new one, redesigned with XR uppers to take more power would be the ticket on lots of smaller single cats for efficiency and speed.
airating the prop. How is that done? What kind of cat did you put it on?

Mount vertically a 2-3" pipe or hose right above the prop. When the drive is deep it will draw air down to it thus allowing it to slip therefore limiting the torque it can absorb which protects the driveline. Also can be used to allow the engine to rev up to it's powerband.

That is an awesome improvement! This BH must be the best kept secret for single engine cats. You nailed it about carrying the bow. Only production boat I know with them was a 29' Scarab that came stock with twin SBCs

It's a true surface drive (rooster tails and all), right?

Hey JS,
The new Velocity 290 with the VR1 hull is pretty sweet.The wife and kids like the 15"flat screen DVD and enclosed head.I like the 83mph on GPS with a 525 efi spinning a 5 blade Hydro prop.It handles awsome in any conditions !!
