Abstract: A bidirectional steering mechanism is disclosed for a vehicle such as a motor boat wherein a manually steerable wheel is connected through the steering mechanism to steer an outboard motor; however, wave action or torque reaction from the motor cannot act in an opposite direction through the steering mechanism to the wheel. This provides a non-kickback steering control mechanism. The steering mechanism has first, second and third elongated members, the first connected to the steering wheel, the second connected to the outboard motor, and the third restrained against longitudinal movement. Wedge means and lock means act between the second and third members as urged by spring means with trip surfaces movable with the first member to relatively unlock the second and third members after a first lost motion distance and then actuator means acts after a greater second lost motion distance to move the second member from the first member.
