  • Patent number: 10962047
    Abstract: Tie rod assemblies include a tie rod body, a coupling feature having a shaft, a ring positioned on the shaft, and a bushing rotatably coupled to the shaft. At least a portion of the shaft is positioned within the tie rod body, with an external threaded region of the bushing engaged with an internal threaded portion of the tie rod body to couple the coupling feature to the tie rod body. The ring is sized such that it is configured to prevent longitudinal translation of the coupling feature with respect to the bushing, via engagement with the shaft. The shaft is free to rotate within the bushing and within the tie rod body, to provide a tie rod assembly having a swivel end. The bushing may be rotated to adjust the length of the tie rod assembly. Related methods include assembling and adjusting the length of the tie rod assembly.

    Abstract: A marine outboard motor comprises first and second cylinder blocks connected to a crankcase having a crankshaft. Each cylinder block contains a cylinder having a cylinder central axis, and a piston reciprocally mounted within the cylinder. First and second planes are defined by the first and second cylinder central axis and the crankshaft axis. The first and second planes are at a first angle less than 120 degrees. The exhaust manifold is at least in part within a valley formed between the first and second cylinder blocks. A configuration with a third cylinder block opposite to the first and second cylinder blocks is also described. A third plane is defined by a third cylinder central axis and the crankshaft axis. The third plane is at a second angle to the first plane and at a third angle to the second plane. The second and third angle can be equal.

  • Publication number: 20140342622
    Abstract: Disclosed herein is a trimmable pod drive assembly that includes a pod drive unit having a transmission assembly secured to a steering unit, a gear case assembly coupled to and rotatable by the steering unit about a steering axis, and a propeller rotatable about a propeller driveshaft axis extending through the gear case assembly so as to generate thrust along a thrust vector. The trimmable pod drive assembly further includes a trim assembly secured to the pod drive unit in a manner allowing for rotation of the pod drive unit about a trim axis that is substantially perpendicular to the steering axis, wherein actuation of at least one component of the trim assembly causes movement of the pod drive unit and the thrust vector about the trim axis.

  • Publication number: 20140242857
    Abstract: A variety of multi-use, configurable watercraft is disclosed. A first type of watercraft used in a first water-based activity may be used as a component in a second type of watercraft used in a second water-based activity. For example, a stand-up paddleboard (SUP) may be used for paddle boarding, and then converted into a kayak, sailboat, catamaran, motorboat, or other type of vessel by adding one or more components to the SUP. In one embodiment, two paddleboards are used to construct a variety of multi-hull watercraft.

  • Patent number: 8794169
    Abstract: In a power steering apparatus for a small vessel, an electrically driven assist device (26) and a helm pump (27) formed of a swash plate type axial piston pump are arranged in parallel on a common base (28). The electrically driven assist device (26) and the helm pump 27 are connected through a transmission system (34) under the common base 28 and integrated into a steering oil pressure generating unit (6) functioning as the power steering apparatus. The electrically driven assist device (26) is carried on an instrument panel (3). The parallel arrangement of the electrically driven assist device (26) and the helm pump (27) allows the steering oil pressure generating device (6) to be reduced in vertical length, so that it is possible to shorten the distance between the instrument panel (3) and a bottom (2) of the vessel and to lower positions of a handle and an operator's seat, thereby realizing the low center of gravity.

  • Patent number: 8790145
    Abstract: A collapsible and disconnectible for storage yet extending for use emergency motor drive unit for a boat. A motor is secured to a hollow drive-shaft pipe segment. Another pipe segment is attached to the end of that pipe segment and has a propeller at its end. A drive shaft of the motor is coupled to the propeller by flexible tubing passing through the hollow bores of the pipe segments. A third, and possibly fourth and fifth, pipe segment(s) is(are) provided between the other two segments to extend the length of the overall device. At least one pipe segment has a vertical support post which allows the device to be selectively held in the receptacle of an anchor light receptacle, when needed. A clamp block and ball swivel allow for rotational, lengthwise, and angular movement of the pipe segments to adjust the motor and the propeller to maximize efficiency of use.
