  • Patent number: 4722705
    Abstract: A marine propulsion device including a propulsion unit, a gimbal housing for mounting the propulsion unit on a boat transom for swinging movement, and a sending device for sensing the general angular position of the propulsion unit. The sending device comprises a resistance element having an end, a fixed resistor in parallel electrical connection with the resistance element, and a wiper supported on the gimbal housing for pivotal movement along the resistance element. The marine propulsion device also includes structure operable between the wiper and the propulsion unit for moving the wiper along the resistance element in an amount which is variably proportional to the amount of swinging movement of the propulsion unit, and for moving the wiper beyond the resistance element end as the propulsion unit moves beyond the predetermined angle.
