  • Patent number: 8997628
    Abstract: The present invention relates to a position sensor and limit switch apparatus for an actuator. The actuator has a cylinder and a piston with at least one magnetized portion reciprocatingly disposed within the cylinder. The apparatus includes an elongate housing aligned parallel with the cylinder. A magnetostrictive linear displacement transducer is disposed within the housing for sensing the position of the at least one magnetized portion. The apparatus includes a switch means responsive to the transducer for operatively interrupting actuation of the piston upon the at least one magnetized portion reaching a limit position.
    Type: Grant

  • Patent number: 8007330
    Abstract: The present invention relates to a steering apparatus for a marine craft. The marine craft has a stern and a propulsion unit. The steering apparatus includes a stern bracket connectable to the stern of the marine craft. A swivel case is connected to the stern bracket. The swivel case defines a steering axis. The steering apparatus includes an electric motor coaxially disposed within the swivel case for swivelling the propulsion unit about the steering axis. The steering apparatus includes a gear reducing unit having an input operatively engageable with the electric motor and an output. A first member operatively extends from the output and is connectable to the propulsion unit.

  • Patent number: 7497183
    Abstract: An apparatus and method for providing power assisted steering for a marine craft having a manually operable steering pump and a hydraulic steering actuator. A powered hydraulic pump is hydraulically connected between the manually operable pump and the actuator. Hydraulic fluid volume output of the steering pump and hydraulic fluid volume output of the powered pump are sensed. The fluid output of the steering pump is compared with the fluid output of the powered pump and the powered pump is operated so that the output of the powered pump is commensurate with output of the steering pump.
