thru to over the hub exhaust..do I adjust pitch?

[conig]

Does some type of baseline exist when going from a thru hub exhaust to an over the hub like a cleaver or chopper? I know the charicteristics of each but it seems between exhaust flowing over and surfacing the prop I would need more pitch.

Do we have rule of thumb? I am running a 10x13 through hub stainless at my target 5500 rpm. 3 inch setback 2 inch over standard.

Often the over the blade props have more blade area and no change in pitch is needed. I am guessing that this is a low hp motor due to the 10x13 prop size. It really is a trial and error thing as you change to a OTH prop you generally start raising the motor height to surface it. When surfacing a prop it will usually turn a few hundred more rpm's vs a buried TTH prop.
