Default Gearvbox/Prop Size help

Hi all I need your expertise
I'm looking for gearbox/prop size for motor/esc/battery I already have

motor

ESC Thunderbird-36:

Battery
Flightpower EVO-20 (1200mah 20C) 3s LiPo

want to go with a folding prop and hub so it can be modded
Now I have to confess as it will affect your selection this is not for a plain as of right now it's for a very light hydro style airboat with as little drag as possible
this has never been done in the airboat world so I am asking for your help
I know it will not be as fast but if I can get half as fast I will be very happy
Right now I need to beet 80 sum mph as it is the top speed of are little compaction at this point, I hope to go over 100mph
I have been looking around and think the gearbox round is the way to go for the thrust to weight ratio
I appreciate any and all thoughts on this even negative ones
