    Hi I am a new member with limited experience, is it possible that brushed motors will work when underwater. They are Johnson cordless drill motors.

    Sure, if you run it in fresh water. Blow it dry when doing your post-run maintenance. Grind open the motor case around the commutator to facilitate flooding/draining and post-run maintenance.

    Be prepared to replace the motor every season.
