Tips

The horizontal thruster nut has right-handed threads. Turn the thruster nut counterclockwise, when viewed from the rear of the ROV, in order to loosen it.

If you cannot turn the horizontal thruster nozzle nut, grasp the horizontal thruster nozzle assembly and nut and turn them both at the same time. This should free the nut enough that it can be turned by hand.
