Most Bravo props are really 1" lighter in pitch than stamped. If you go to a 5 Blade Maximus, then you really need to drop down to at least 30's.
Your rpms will still most likely decrease by about 200-300 if you go with 30 Maximus props. I would also call BBlades and/or post in the prop section.

I run 32 maximus's, I also own a set of 32 bravo's

My propshafts are 3" below the bottom of the boat,
it has Stellings boxes.

Cruise speed, at 3500 rpms the max's run 55 mph, at 3800 rpms the the bravo's run 52 mph.

The fastest I've had the max's was 94 @ 5500 on the perfect
day, ( normal average is 88-92 )the best I had the bravo's run was 89 @ 5800 ( rev limiter)

The bravo's just dont work that well on my boat.

And yes, I've broken my share of drives...but I've witnessed
the same junk XR upper gearsets break behind 500's and
4 blades.

i run the 34 MAXIMUS FOR CRUISING. 3500 RPM 62 MPH. Poker runs etc, i switch to 32 Maximus 3500 RPM 55 MPH. These are large props and both sets need the diffuser rings cut way back. With the rings i had to much transom lift. I tried 32 bravo's and had a hell of time getting on plane. Maybe because of Imco boxes and -2 shorties on SCX's. 32 maximus 102 MPH 5400
