I havent had the chance yet. Im going to take this ROV out and run it down to 200' when I get it all back together. Im putting a Manipulator and camera tilt etc. There potted inside of their housing and oil filled (At least in the gearbox) so I dont forsee an issue with depth. Cant be any worse then a Bilge motor.

Im using a piece of short tubing with a bolt run inside the round open end on the bottom. I made the new skid out of aluminum. Its actually realy easy to mount these.

To use computer fan blades for powerful thrusters, you can mount them to a rc brushless motor and buy a motor controller for it at a relatively cheap price, making a good thruster:

It also contains an other useful bit of info the circut of Awni Zaidoon to switch a ROV on and off with a magnet.
