I have a boat/power very simular to yours....but if your boat were mine, then I would probably try an untouched Hydromotive a 30" or 32" P5X (5-blade) for a baseline start. My disclaimer is that I am not a prop/boat expert, but that is where I would start.

Had a heavier boat, 38 Fountain, with 600's and shorties, but the revlimiters set at 5300. We ran 32 pitch 5 blade Maximus. With a higher redline, 32's should be a good place to start.

VV, Keep your money in your pocket until you are ready to run the boat, then call Brett at BBlades and let him send you some demo props. Their demo/trial deal is real reasonable, and you won't end up with a bunch of props that don't work.

That's the best advice I have got so far. I did find out from Matt the 33p 6 blade won't work for me.

The chances of you surviving prop testing is pretty minimal

Twin 700 supercat engines in a Velocity? Wow. I had 575 a side in a 30 and got to see God a couple of times. 700's should be unbelievable.
