  • Patent number: 4826459
    Abstract: A tilt mechanism for an outboard motor includes a series of trim and shallow water operation positions which may be preset by the operator and from which the motor may be temporarily tilted up without engaging and being held in a higher tilt position. Correspondingly, elimination of the condition requiring or causing the temporary tilt-up allows direct return of the motor to the original trim position. Alternately, a manually operable trim ratchet assembly allows the operator to temporarily tilt the engine to and have it held at a higher trim position if desired. Disengagement of the trim ratchet assembly also allows direct return of the motor to the original trim position.

  • Patent number: 4815994
    Abstract: A technique for lubricating a standard outboard motor steering mechanism comprises removing and discarding the conventional nut captivating the motor tilt tube to the motor brackets. A hole is drilled through the tilt tube. The conventional nut is replaced with a nut having a radial threaded passage through which lubricant is added to the interior of the tilt tube where the steering mechanism is located. The nut of this invention includes an interior groove so the tilt tube hole and radial passage do not have to be radially aligned. In another embodiment, a similar looking arrangement is incorporated into one of the motor brackets through which the tilt tube extends.

Supported on the arm for movement along the longitudinal axis thereof is a coupler member having drive cable connected thereto, the drive cable being wound about suitable blocks so as to enable positioning of the coupler along the axis of the support arm in response to movement of the cable. The coupler member has a plurality of apertures spaced longitudinally therealong which enables the selective connection of the coupler member at any one of its apertures to a mating attachment member on the tiller. Thus, the coupler is driven laterally in either direction in response to movement of the cable, thereby actuating the steering control accordingly.

  • Patent number: 4348977
    Abstract: A water conveyance having two hull members spaced from each other and carrying a hydrofoil toward the stern thereof and an airfoil or wing toward the bow. The hydrofoil and airfoil cooperate to lift the hull members from the water to reduce water resistance and increase travel speed. The hydrofoil is movable vertically to accommodate the raising and lowering of the hull members during start up and slow down. Flaps on the wing control the attitude of the conveyance and, in a preferred embodiment, the flaps are controlled automatically to maintain a generally horizontal attitude.

  • Patent number: 4311471
    Abstract: A remote steering device adapted for attachment to a stern drive unit and an outboard motor affixed to the stern portion of a boat. The remote steering device comprises a pair of elongate members rotatably affixed to one another and having longitudinal axes of rotation, adapted such that a first elongate members may rotate about its longitudinal axis relative to the second elongate member without causing rotation of the second member. One of the elongate members is provided as a pair of telescoping members in order to vary the distance between the outer ends of the device. A ball-joint is adjustably affixed to each outer end of the remote steering device, and brackets are provided for attaching the device to the stern drive unit and the outboard motor. When the stern drive unit is raised to its upper inoperative position, the elongate members securely affixed to the stern drive unit and the outboard motor may rotate about the longitudinal axis to avoid twisting stresses.
