I have a labbed 32 bravo 1, how far can it be labbed down? I need to pick up 700-800 rpm's

Not that far. If its alraedy labbed, probably a couple hundred rpms. 700-800rpms= 4 inches of pitch too much prop.

If you have a single. I have a 30p Bravo 1 4 blade that BBlades has done some work on. could work out letting you try that.

I am a single. Boat came with a BBlades 32 bravo 1 -4 blade, but it lived in Wisconson then, alot cooler than so. cal. and lake havasu. top rpm about 4800. I tried my buddies labbed 28 bravo 1 -4 blade and hit the rev limiter at 5600. so guessing a 30p may be the ticket?

yes, 30p is what you need.
