Can brushed motors run underwater?

I know that brushless motors can run underwater, but can brushed motors do so for extended periods of time? This is assuming the brushed motor has no sensors or internal circuitry.

    Yes but the water will reduce the output. You’ll also have a corrosion problem down the road. Salt water will be even worse. If you can, sealing the motor with something like a petroleum jelly will give some protection.

    No.

    In a brushed motor, you have the conducting parts ("brushes") in direct contact with the water. Electrolysis will ensue - unless the water is sufficiently conductive to give you a straight short across the brushes.

    yes but generally not for 'long' periods of time water promotes corrosion .. it wont hurt them to be exposed to water if maintenance is kept up ...
