This question has probably been asked a few hundred times, but are water cooled motors and escs water proof? In other words, do I need to use the intake and out-put tubes or can I just submerge the motor and esc?

No, you can't submerge them. It usually means that they are equipped with tubes that you plumb into piping that picks up water from the outside and discharges it, a bit warmer, back to the outside world.

Some esc's are waterproof, but thats only IN CASE you get water inside. You're not supposed to fill up the hull with water for cooling if thats what you mean.

I have seen the heat sink to a ESC mounted in the hull of a boat, such that it is outside the boat, in the water. It is very effective, only problem is if you need to work on the ESC, your going to have to pull it out of the hull of the boat.
