I would say you are looking at something like 11-1/2 x 13, assuming your lower unit is a 2:1 ratio. If the ratio is around 2.33:1, then I would say you could bump up to a 15 pitch.
Hopefully this gives you a start on your rig. Enjoy the new powerplant and keep us posted when you get it on and ready to go.
