Brushless Wild Cat?

[FighterCat57]

I have a 500' body of water really close to me that's small for a fast boat, but fun in the wild cat.

What I want is to use my standard transmitter/receiver setup...

... 5+ more MPH and 20 minutes of run time.

It's pretty clear that the mounts can be taken out and the motors can be changed and there's room for an ESC, maybe two...

What I don't know is the Kv of the stock motors and the size?
What kind of brushless setup would work?

Much smaller than I've worked with in the past and probably best to ask before tearing in to it. =)
