Prop help needed
 

I am running 2 carburated 500 HPs' in my 2002 28 sport .
X dimension is at 16.5".
Is anyone out there running this setup ?

I picked up a set of 28 Bravo 1s' and am turning them at
5200 RPM for a "Real " speed of 85 mph on the GPS .
( I have 2 GPS's which show same speed ) .

I may try a set of 30s' but do not have any readily available .
I was wondering if anyone had experience with this power
and how much prop was used without killing the throttle response ?
