Questions?? Help. Drive a paddle wheeler

Hey all!
I'm new to rc boats, but not new to RC. Played with planes trains,cars truck, helis, nitro, gas, electric. . OK.

I have a co-worker looking for inexpensive means to drive and control a self built paddle wheeler. I have been searching the online hobby stores and finding waterproof radio, receiver and esc seems to be simple enough.
Need a motor and drive system.
I was thinking of using a 4wd buggy hubs and belts for the mechanism? Thoughts?
Another option I was thinking is using heli starting belt and gear set? Thoughts?
Motors?? Do they make waterproof motors? Can you run a brushless?
I understand they wont be submerged, but there is always splashing, and a good chance of water infiltration.

He isn't quite a craftsmen but here is his "mockup"

Brushed motors should be ok with water. Brushless can be waterproof (easier with sensorless).
Belt drive is probably the way to go. Going to need a good amount of gear reduction, you don't need that paddle spinning fast. May have to use transmission (maybe Axial or some other brand), put a small pulley on the output and large pulley on the paddle wheel.

Thanks. I was thinking the drive gear will have to be large, That,s why I was thinking gas heli starter gears, they are a good size, and then use the hub off an electric starter. trimmed up to fit on a motor shaft. What size motor should we be looking for?
