摘要： A drive arrangement for a marine vessel. The drive arrangement includes an upper drive part configured to be mounted onto an outside of a transom of the marine vessel. A lower drive part is connected to the upper drive part to be fixed in a vertical direction in relation to the upper drive part. The lower drive part has a hydrodynamic configuration and is provided with at least one propeller. A transmission system is arranged to transfer a drive torque to the propeller from a drive source system connected to the transmission system. An outer surface of the upper drive part substantially is made up of a plurality of surface sections connected by one or more edges. Each of said surface sections has a shape corresponding to a so-called ruled surface that can be generated by the motion of a straight line.

摘要： An outboard motor includes a swivel bracket supporting a drive shaft housing such that the drive shaft housing is pivotable about an axis thereof and is movable in an axial direction thereof, a steering adjuster attached to the swivel bracket and configured to increase or reduce a rotational resistance force of the drive shaft housing against the swivel bracket, and at least one spacer mounted to the drive shaft housing at a position adjacent to at least one of both ends of the swivel bracket in the axial direction. In a state in which the spacer is mounted to the drive shaft housing, the drive shaft housing is restricted from moving in the axial direction with respect to the swivel bracket. A dimension from the swivel bracket to a rotation shaft of the propeller is changed by changing a mounting position of the spacer.

摘要： An apparatus for mounting a pedal propulsion system to a watercraft, having a mount portion configured to be attached to the watercraft, a link support, and upper and lower links pivotally connected to the link support and to the mount portion. The link support and upper and lower links are configured to form part of a four-bar linkage arrangement and to simultaneously move together between an extended, operable position for operating the propulsion system, and a retracted, stowed position elevated above the extended position, for loading, transporting, unloading and/or launching the watercraft in the water. A column clamp is configured for selectively fixing a drive column of the pedal propulsion system to the link support, wherein the drive column, the link support and the upper and lower links are configured to simultaneously move together between the extended and retracted positions.

摘要： An outboard motor includes an engine, a generator to generate power by driving of the engine, a driving force transmitter to transmit a driving force from the engine, a propeller shaft to rotate by being switched from a neutral state in which a clutch is disconnected from the driving force transmitter of the engine at idle to a non-neutral state in which the clutch is connected to the driving force transmitter, and a controller configured or programmed to perform a control to reduce a rotation speed of the engine by regeneration of the generator based on a user's switching operation on a shift operator to switch the outboard motor from the neutral state to the non-neutral state, and then connect the clutch to the driving force transmitter while rotating the engine.

摘要： Conventional surfboards enable a rider to catch a wave and ride towards the shoreline while utilizing the power of the ocean to enjoy the ocean waves uniquely. A low-profile motorized surfboard has been developed to assist riders who may have a disability or struggle to get into the position necessary to begin riding the waves. The surfboard may comprise at least one propeller and electromechanical motor, which may provide propulsion for the rider. The surfboard may have an internal power system and supporting circuitry for safe and reliable propulsion. The motorized surfboard may have a low-profile system that is collapsible and allows for the rider to enjoy the surf as if the surfboard were a conventional system. The system may also function to return the rider to the shoreline.

摘要： In an example, a compliant shaft enclosure support system for coupling to a shaft enclosure surrounding a shaft includes a bar having a first member slidably coupled to a second member. The bar is oriented along the pitch axis of the shaft. A first bar end of the bar is rotatably connected, around the roll axis and pitch axis of the shaft, to the shaft enclosure at a first connection. A second bar end of the bar is rotatably connected, around the roll axis and pitch axis, to the structure at a second connection. A link is rotatably connected, around the roll axis, at a first link end to the bar, at an intermediate location spaced from the first and second bar ends. The link is rotatably connected, around the pitch axis, at a second link end to the shaft enclosure at a third connection spaced from the first connection.

摘要： The human powered hydrofoil bicycle includes multiple subsystems integrated together including a structural frame subsystem with associated steering and tiller module, a hydrofoil subsystem to provide vehicle lift, and a powertrain subsystem. The structural frame subsystem may be fitted with buoyancy modules to provide the overall vehicle with a near neutrally buoyant character. The structural frame subsystem also supports a seat for an operator and provides structural support for the steering and tiller module for the hydrofoil subsystem and the drivetrain subsystem. The hydrofoil subsystem includes multiple hydrofoil elements at lowermost portions of the vehicle. These hydrofoil elements generally include in a preferred embodiment a larger rear foil and a smaller front foil. The powertrain subsystem generally includes pedals rotatably supported on the vehicle at a convenient location for engagement and driving by feet of an operator. Power transmission elements extend from the pedals down to a prime mover such as a propeller.
