new/getting old brushless crap.. make a boat?

[tha5150]

just moved and have a canal in my back yard. i have a Novak 8.5 brushless with ESC for my drifter and a Medusa Afterburner 2300kv with MMM esc on the buggy. DC2 digital remote. i havent played with either for about a year and curious if i could buy a few things and make a decent boat. i would think i need a hull and prop and driveshaft. thats pretty much it right? of course the spur gear or whatever.


any and ALL advice is appreciated.
