Will a small waterproof fountain pump work as a thruster?

I'm kind of new to actually building ROVs (although I've been dreaming about it for years ) Would something like the following fountain pump work as a thruster for a small ROV?

I thought about using it to pump water to push the ROV along (is that called jet propulsion?) instead of modifying it and attaching a propeller. Would something like this work? Has anybody tried it?
I have in mind a fairly small ROV, probably a foot long x 8 inches wide. Would two of the above pumps (one on each side) propel a small ROV like that?
I had in mind to use a raspberry pi and a L298N motor controller to control the three thrusters, with power supplied by PoE. Would a brushless DC motor like this work with the L298N just the same as it would with a brush motor?
I'm sure people have talked about this before, but I wasn't sure what to search for to find the posts about it.
Thanks for the help!
