I want to build a small ROV for some underwater fun but had a question about the motors. I thought about using a similar system to a regular boat where [Speed Test](https://testmyspeed.onl/) the prop shaft has a seal around it, keeping the water out of the engines/motors, but as I do more research, I think if I use brushless motors, they can be run underwater [Scrabble Word Finder](https://scrabblewordfinder.vip/) (wiring obviously would go into a waterproof area). Is this correct? What are some common ways for building waterproof robots? ---

Hi @gamora77 Welcome! Yes, you are correct, brushless motors can run underwater and our [M100](https://bluerobotics.com/store/thrusters/motors/m100-motor-r1/) and [M200](https://bluerobotics.com/store/thrusters/motors/m200-motor-r1/) motors have special coatings and components to do a better job of preventing corrosion than stock brushless motors. Adam, one of our engineers, wrote a good guide for DIY and Competition ROVs that goes over the basics of underwater vehicle construction: [Using Blue Robotics Components on a Competition ROV](https://bluerobotics.com/learn/br-components-for-competition-rov/)
