Question about jet drives

[boatnewb]

Is it possible to use a jet drive in a submersible, ie run it with the motor and drive completely submerge? Thanks for any feedback

[Submarine Tom]

Yes, you bet.

Hey just wondering, I'm building an underwater vehicle, which weighs about 5-10 lbs out of water, and I want to use 4 motors, one on each corner (the robot is a rectangle), for control.
I have searched for a little while and the best i could come up with were jet drives, I considered bilge pumps for a little while.
Any recommendations for motors?

Thanks

Absolutely. Bilge pumps. There is a well known, old design out there that

uses them to make an awesome little ROV. I believe they were "Rule"

pumps. You'll find a PDF on how to build it on the Internet but it's not easy

to find as I recall. I have driven/operated it in a tank. It was great and

easy to drive. This is the route I would go if I were in your shoes.

If you can't find it, personal message me (left click on my name/handle).

I found the book name and authors:

"Build your own underwater robot" by Harry Bohm and Vickie Jensen
