The aqua capability is cool.  Nice work

When I see this bot I was wondering for waterproof ultrasound. Is it still working inside of any transparent material? Lake glass, plastic etc?

I'm not sure, but I think that any solid material reflects/refracts the ultrasound waves, so it wouldn't  work very well.

Looks good. I have found from experience that your ultrasound can fail if it gets wet. I think it was mainly due to the water shorting the circuitry so you might be able to just spray some clear varnish over the PCB to protect it. Do not get varnish on the transducers.

It looks that I've been lucky with it. One year ago, when I was creating the FoamBoat with my friend Purdom, it fell on the water one or two times and still works well :D

Cool! I hope you get to test it soon, I wanna see a video of it in the water.

Good idea...BoatBots are not that often here.

The bootles are a good choice for the body but the propellers are not the right ones (you mentioned it).

How did you seal the shaft to keep the water out of the bottle and the motor dry?

I just used Polymorph :)
