  • Patent number: 8468964
    Abstract: Methods and arrangements to redirect a forward thrust generated by a propeller of a watercraft to provide a non-forward thrust are disclosed. More specifically, embodiments comprise a control surface to redirect the forward thrust from the propeller. Based upon a position (i.e., distance and orientation) of the control surface with respect to the propeller, the redirection generates the non-forward thrust or thrusts. By redirecting a component of the forward thrust back toward the bow, the net forward or reverse, port or starboard thrusts and rotational thrust can be adjusted in fine increments. For instance, by adjusting the amount of prop wash hitting the control surface, the magnitude of the redirected thrust from the control surface can be adjusted. Further, adjusting the angle of the control surfaces adjusts the direction as well as magnitude of a reverse thrust component. The net thrust can be in any direction and rotational.

  • Patent number: 7442104
    Abstract: A tiller handle assembly for an outboard motor is provided that comprises a steering handle having a generally hollow body. A throttle grip is attached to a front end of the steering handle, and a shift mechanism coupled to the steering handle. The shift mechanism includes an moveable operator that can be moved at least between two positions: one of the positions corresponding to a drive operational mode of the outboard motor and the other position corresponding to a neutral operational mode of the outboard motor. A sensor device is disposed within the hollow body of the steering handle and is configured to determine whether the movable operator is positioned in one of the two position. The location of the sensor device within the hollow body makes mounting and maintenance of the sensor device easier and generally isolates the sensor device from water.

  • Patent number: 7404747
    Abstract: Proposed is a height adjusting mechanism for a tiller handle (23) of an outboard motor (1). An adjustment piece (45) is detachably attached to the front end of a handle support bracket (22) which extends rearwards from the outboard motor main body (3). The adjustment piece is configured to be attached to the front end of the handle support member in two or more different positions and provided with a corresponding number of spacer portions (47-50) having different thicknesses so as to interpose a selected one of the spacer portions between corresponding stopper surfaces (41, 42) of the tiller handle and handle support bracket depending on the positions of the adjustment piece. Thereby, the height adjusting mechanism for the tiller handle is avoided from protruding laterally or vertically from the base end of the tiller handle so that the external appearance is not impaired and interferences with the surrounding parts can be effectively prevented.
