Abstract
A remote, electrical steering system for marine vehicles including an electrical motor operable by a control and power circuit to rotate a drive screw having a screw connection to a nut in a drive tube for moving the drive tube in translation to cause steering movement of a motor/rudder with the control circuit sensing various fault conditions for placing the electrical motor in a brake condition to inhibit inadvertent steering and with the screw and nut connection resisting backlash from the motor/rudder to inhibit inadvertent steering and isolate the electrical motor and associated gearing from backlash loads.
