Howdy everyone.
I have been doing some research online to see if it is feasible, or even a good idea to try to build an electric surfboard using RC parts. Goal would be to propel a surfboard with a 170 lbs rider on calm water at 20 mph while keeping the parts list under $2000.
There are ready made options on the market already that range from the slightly above resonable Kymera ~3600:

To the scarcely believable prices on the boards from companies like onean (9k+)

There is one DIY board supplier I've found, based in germany, MHZ watersports plus. However these motors, escs, and jet drives are also crazy expensive (escs alone are going for +$1000, any some builds recommend two of them)

There really isn't to much I found about a DIY surfboard on youtube, save for really unhelpful stuff like this:

I've also looked at trolling motors, but found them to be too slow (usually they only are designed to do 5mph) and outboard motors, but they tend to be gas powered and too heavy. Hydrofoil surfboards are also the focus of some development, but it seems too hard to get a motor system spec'd out AND build a foil so I don't want to go down that path.

So that brings me to my question. Does anyone here have any experience specifying parts for a powerful build like this? What parts should I look into? Any particular vendor or solution I missed?
As for my own abilities, I have experience in sizing components for RC cars and airplanes, but very little experience in the electric rc boat world (save for the occasional rip around the lake with a Traxxas Spartan).
