Post subject:  What size prop? DIY -ish Surface Drive

After trolling on this fourm and scouring the DIY sections i decided to build a surface drive with parts and pieces.

First I found a 27" Mud Buddy lower, picked up a Predator 670 motor new, and crashed McMaster & Car.

So... after fabricating a housing for the MB lower and started fabricating a transom mount, the last piece I need is a prop.

Specs are as followed:

Predator 670
Upper gear - 36 tooth 101.6mm
Lower Gear - 45 tooth 124.46mm
Gates 8m-1440-20 gt timing belt
MB 27" lower

What prop would optimize the gears and motor combo.

Boat is a Xpress 1650 with foam still in it. (will be removed after this duck season)

Thanks for all the information.

crap, i'm out of the loop... NOT trolling: "make a deliberately offensive or provocative online posting with the aim of upsetting someone or eliciting an angry response from them."

I meant "cruising". or does that mean something else also?
