What prop for a Yamaha 9.9 Long Shaft

[osprey02]

I just bought a used 1998 Yamaha 9.9 long shaft 4 stroke,
I'll use it on 2 different boats

1) 16' Aluminum North River Drift Boat

2) 17.5 Crestliner Fish & Ski w/ Volovo Penta 3.0 I/O

Both boats will be used to back troll in River currents
Anyone have any Idea what size/pitch prop I can use on the yamaha and not have to change it out every time I change boats? I think I'm looking more for torque, than speed?

I need to pick up a spare, do I need 2 ?

I'm not sure,It's not here yet. It's on it's way by freight. I just bought it last week and the drift boat,I bought yasterday!

I haven't even mounted the kicker bracket on the crestliner yet, figured I'd have a dealer do it, so It won't fall off and the prop will be at the right depth when I go to use it!

I guess I'll just order a matching spare, when I see what I have?
I have no idea what the previous owner had it on,
and there are 6 to choose from:
