摘要： A marine propulsion unit is described. The marine propulsion unit allows for shallow, obstructed, or otherwise impeded operation of a vessel through a novel marine propulsion transfer unit that is, or can be, mechanically coupled to an outboard motor or other similar marine motor. A mount for raising and lowering the marine propulsion unit in a generally vertical direction allows for adjustment of operating depth of the marine propulsion unit to accommodate a wide range of operating conditions from shallow and obstructed water to traditional deep water operation.

摘要： An outboard motor for a marine vessel application, and related methods of making and operating same, are disclosed herein. In at least one embodiment, the outboard motor includes a horizontal-crankshaft engine in an upper portion of the outboard motor, positioned substantially positioned above a trimming axis of the outboard motor. In at least another embodiment, first, second and third transmission devices are employed to transmit rotational power from the engine to one or more propellers at a lower portion of the outboard motor. In at least a further embodiment, the outboard motor is made to include a rigid interior assembly formed by the engine, multiple transmission devices, and a further structural component. In further embodiments, the outboard motor includes numerous cooling, exhaust, and/or oil system components, as well as other transmission features.

摘要： An integrated jack plate and kick up bracket is provided that is useful and safe even at relatively high boat speeds (e.g., in excess of 10 miles per hour). The bracket uses a jack plate to raise and lower an outboard. The jack plate is hingedly connected to the boat transom such that the jack plate assembly can rotate if the outboard has not been raised high enough to clear a submerged obstacle which the lower unit of the outboard motor strikes. Rotation of the jack assembly about the hinge is limited by a limiting strap affixed to the transom (or transom mounted portion of the bracket) and a lower portion of the jack assembly.

摘要： The invention provides an internal combustion engine comprising a piston mounted for reciprocating linear motion within a cylinder along a cylinder axis. The piston is coupled to an output shaft by a power transfer assembly arranged to convert linear motion of the piston to rotary motion of the output shaft. The piston has a first head moveable within a first chamber and a second head opposite the first head and moveable within a second chamber. The power transfer assembly has a lubrication system for lubricating moving components of the power transfer assembly. The lubrication system is sealed from the first chamber and the second chamber to prevent the passage of fluid from the lubrication system into the first chamber and the second chamber.

摘要： A jack plate has a pair of transom mounting brackets and a pair of slide plate holders. There is a slide plate holder lower cross member and a pivot pin. The pivot pin rotatably couples the transom mounting brackets and the slide plate holders. There is a slide plate and a single unit hydraulic lifting assembly. The hydraulic lifting assembly is coupled to the lower cross member at a location right of the centerline of the lower cross member.

摘要： A marine propulsion system for shallow waters, swamps, savannahs and the like includes a rotating propeller shaft supporting a propeller. An anti-cavitation body defines a partial cylinder having a longitudinal axis adjacent to the propeller. The propeller generates a vacuum between the anti-cavitation body and a surface of a water body. First and second wings adjacent to edges of the anti-cavitation body are generally planar and operatively angled towards the bottom of a water body. The first and second wings are adjusted to run below the water body surface and seal the anti-cavitation body to maintain generated vacuum. A first thread is cut in a first helical direction at an end of the rotating propeller shaft adjacent the propeller, and slightly more distal therefrom a second thread is cut in a second helical direction opposed to the first thread helical direction. The second thread drives matter away from the bearing.

摘要： Embodiments of a watercraft are disclosed herein. One embodiment of a watercraft includes a board and a propulsion system secured to the board. The propulsion system has a water outlet portion and a water intake portion. The water intake portion includes a rim having a cross-sectional area that tapers along a length of the rim in a direction moving toward the water outlet portion. The propulsion system further includes a first blade having a first end connected to the rim and a second end opposite the first end. The second end of the first blade is a free floating end. The propulsion system also includes a first motor located between the water outlet portion and the water intake portion. The first motor has a first rotor component and a first stator component. The first rotor component is configured to rotatably drive the rim.

摘要： A trim control system automatically controls trim angle of a marine propulsion device with respect to a vessel. A memory stores trim base profiles, each defining a unique relationship between vessel speed and trim angle. An input device allows selection of a base profile to specify an aggressiveness of trim angle versus vessel speed, and then optionally to further refine the aggressiveness. A controller then determines a setpoint trim angle based on a measured vessel speed. If the user has not chosen to refine the aggressiveness, the controller determines the setpoint trim angle from the selected base profile. However, if the user has chosen to refine the aggressiveness, the controller determines the setpoint trim angle from a trim sub-profile, which defines a variant of the relationship between vessel speed and trim angle defined by the selected base profile. The control system positions the propulsion device at the setpoint trim angle.
