Prop Pitch change? for 90hp to F75 swap

[Hesh]

the 90hp use tor run with a 13? x 17-K prop.
I will be replacing the old 2002 90TLRA with a new F75TLR on a 2002 SeaPro 170CC (~1000 lbs)
Is any change required for the Prop Pitch to maintain the same boat performance?

Your not going to have the same hole shot, going from a 2st. 90hp to a 4st. 75hp. I would think at least a 2" drop in pitch.
