  • Patent number: 4827860
    Abstract: A foot operated powered steering control for an outboard motor used in a boat comprising a bidirectional motor which drives a winch carrying a pair of steering cables in opposite winding directions. The steering cables are connected to the outboard motor of the boat in such a manner that as the bidirectional motor operates in a forward rotational direction, one of the cables will be wound around the winch as the other cable unwinds, thereby causing the motor to turn toward one side of the boat, and as the bidirectional motor operates in the reverse rotational direction the other cable will be wound around the winch as the first cable is unwound, thereby causing the motor to turn towards the opposite side of the boat.

  • Patent number: 4746311
    Abstract: A steering drive system for electric fishing motors of the type having a motor-propeller assembly supported at the lower end of a motor tube. The motor tube is driven through a friction drive arrangement by a steering gear that is rotated through a gear train by a steering drive motor. To limit the rotation of the steering gear, and thus limit the rotation of the motor-propeller assembly, a limit switch is triggered by a simple actuator driven also by the steering gear. The unique arrangement permits the motor-propeller assembly to be turned through a full range whether in forward or reverse without use of complicated gears, belts or chains.
