Just a guess... but maybe try some bravo 32p 4 blades to get a base line, then go from there.... New motors I'm guessing?

What is your target WOT rpm? You plan on propping for accelaration, cruise, or top speed?

I am going for top speed and i was thinking 32p... not new motors just new boat and new motors in the 33 avs 675hp

Start with your old props.

Whats redline or operating RPM?
Any weight change?
What was your old props pitch & blades?

Do you have a target WOT RPM? What prop are you planning on starting with, Bravo?

I am running 34" Bravos with added cup (labbed/matched) on a 34' Phantom with twin 520 hp motors, 5050/5100 rpm @ 91 mph. I would think with that much hp the 34" props would be the ticket.

If those motors are making 675 and you want to spin 5300/5400 the 32" Bravos would get you there.

Are you spinning 5500 rpm with the 30" Bravo with the 675 hp motors? The 32" Bravos would get you to 5300 rpm in theory.
