140 magnum pump, prop choice?

[haggis]

I bought a secondhand 140mag pump for my sj a while back, that came with a prop that had been repitched. The previous owner was unsure of the pitch and the original marking had been rubbed out.
It's def not right for my setup thoe, so could anyone recomend a suitable prop pitch?

I've got a ported Jetworks 61X big bore with ATP TL, 200psi, and a 140 mag. I run a 13/16 with an 82.6mm Skat nozzle.

i run a 144 mag pump, i have a ported 701, protec head with 35cc domes (185 comp.), soon to have dual blackjack 44's with delta force 2 carbon reeds,b-pipe, and i run a cut back 12-17 concord, but art at jetworks suggested i try a shim to space the pump forward to cut the initial load on the engine and let the prop spin up faster.

the concord is a small hub prop,hows that work in a mag pump?
