8S or more esc's that are waterproof?

[Cain]

Are there any 8S or better rated ESCs that are waterproof?

Got a redcat Rampage MT here that I am thinking of converting to brushless, but would want it to be waterproof.

Just not sure if any of the waterproof 6S max escs can be used in the vehicle at all successfully. Not needing wheelie pulling power here, was happy with the power performance of a 1/5 converted savage on 4S with a 1520 1600kv motor and it worked well enough to give some idea.
