ArduPilot Boat - help choosing parts

I’m planning to build a slow going “large” ardupilot boat out of pvc pipes.

For steering I would like to use two engines, and change the throttle to go port and starboard.

I have bought these engines:
But I’m stuck at trying to find the gear I need. I need some propellers, i guess it would be best with a pair of left and right going props?
And I guess i need some kind of a drive/propeller shaft, and something for them to go through the hull.
And I need two ESC.
Any ideas for a parts which fits?
Guess I should have started to ask questions first, and not bought a few parts, but :slight_smile:
So far I have a ArduPilot 2,6 and the engine.
The project will be used together with a Lowrance Fishfinder / Chartplotter as that log more information that just the depth, it also gives an idea about what kind of bottom it is (stones, mud, clay etc)

Take a look here:
They have a good selection of propeller, shafting, and couplers.

I would suggest a motor like this for a PVC pipe boat:

You can steer them with a servo or have them fixed. Typically you would fix them closer to the prow than the stern for stability
