Not recomended if you want them to last,its more cost efective to seal them.
Bin there done that. :shock:

There are several small pumps that have fully sealed motors like the marine Rule bildge pump ,take it apart and install a prop ,instant sealed thruster.Or make your own.

I have run small normal brushed motors in water with good results.

I use motors from car door lock mechanisms. they are made for wet environments.
avoid any motor with a ball bearing, they rust. But cheap motors without ball bearing
proablay work OK.

I replace the motor once a year. cost about 8 euro's (10 $)
