Thanks for the information about the propellers

I want to make something just like this over the summer, thanks for the inspiration!

So the shallower pitch angle propeller (being analogous to a lower gear ratio) allowed the electric motor to operate closer to its peak power output which is at a higher RPM than the higher pitch angle propeller would allow because it caused too much drag for the motor to overcome at even medium RPM's.

Exactly right.

Love to see the initiative and creativity. Question: what type of electric motor allows it to be operated under the water?!

Water is (if not 100% pure) conductive, so it can create shorts in an electrical circuit that is submerged in it. Why does that not affect this motor? Well, the motor coils are made of thick copper wire, and have very low resistance. The resistance of these coils is less than 0.1 ohm. Current through these coils can be >50A. The water has a far higher resistance, so although some current will "leak" between the wires through the water, that will only be very small amount (I'd say < 0.5A) compared to the current through the coils, so it has no effect on the operation of the motor.

Guess you could use two motors and steer with differential thrust. I wonder if the stator coils have a thin layer of alternating h2 and o2 bubbles constantly being blown off?

Not the coils themselves, since the wire is coated with a plasic layer, but perhaps the solder joints are producing bubbles indeed.

Your mount doesn't look very hydrodynamic! I think you could significantly improve the efficiency and probably power output with a 3d printed mount, rough bits sanded and smoothed
