摘要： A marine outboard engine including an engine unit; a drive unit operatively connected to the engine unit; an engine unit housing for supporting and covering the engine unit, the engine unit housing having a top surface; and one or more bumpers connected to the engine unit housing. The bumper projects above the top surface of the engine unit housing; or rearward of an upper rear end of the engine unit housing; or both above the top surface of the engine unit housing and rearward of an upper rear end of the engine unit housing. When the marine outboard engine is located under a boat hatch is in a closed position and the marine outboard engine is pivoted in at least one portion of a tilt range, the bumper is adapted for abutting a bottom surface of the hatch.

摘要： A reciprocating exhaust valve for a two-stroke internal combustion engine has a shaft for connection to a valve actuator, the shaft defining a reciprocation axis of the valve, the reciprocation axis defining a longitudinal direction of the valve; and a blade having: a first end having an arcuate edge, a second end connected to the shaft, two side portions, and a central portion. The blade has a first end portion adjacent the first end that includes a part of the central portion and of each of the two side portions. A width of the central portion is greater than a width of each of the side portions. In the first end portion, a thickness of the part of each of the two side portions is greater than a thickness of the part of the central portion.

摘要： A stern and swivel bracket assembly for mounting a drive unit to a watercraft has a stern bracket having first and second laterally spaced portions, a swivel bracket pivotally connected to the stern bracket about a tilt/trim axis, and a hydraulic linear tilt-trim actuator operatively connected between the stern and swivel brackets. The swivel bracket includes a hydraulic steering actuator, and defines first and second hydraulic steer ports facing outward in a first lateral direction. The swivel bracket further includes at least one drive unit mounting bracket connected to the hydraulic steering actuator for connecting the drive unit to the swivel bracket. The hydraulic linear tilt-trim actuator is located laterally between the first and second portions of the stern bracket, and defines trim-up and trim-down hydraulic ports facing outward in a second lateral direction opposite the first lateral direction.

摘要： A marine outboard engine includes an internal combustion engine assembly that includes an internal combustion engine, a fuse assembly, a fuel filter, a spark plug, a gearcase including one of a propeller and an impeller, a swivel bracket, and a cowling. The cowling includes a service panel disposed on a first lateral side of the internal combustion engine assembly, and an affixed panel disposed on a second lateral side of the internal combustion engine assembly. The service and affixed panels define a split line therebetween and are removably attached to each other. The fuse assembly, the fuel filter, and the spark plug are mounted to one of the first lateral side and the affixed panel proximate to the split line and are at least in part accessible from the first lateral side when the service panel is detached and removed from the affixed panel.

摘要： A marine outboard engine for a watercraft has a stern bracket for mounting the marine outboard engine to the watercraft, a swivel bracket pivotally connected to the stern bracket about a generally horizontal tilt/trim axis, and a drive unit pivotally connected to the swivel bracket about a steering axis. The steering axis is generally perpendicular to the tilt/trim axis. A hydraulic actuator is operatively connected to the stern bracket and the swivel bracket for pivoting the swivel bracket and the drive unit relative to the stern bracket about the tilt/trim axis. A pump is mounted to the swivel bracket. The pump is pivotable about the tilt/trim axis together with the swivel bracket. The pump is fluidly connected to the hydraulic actuator to supply hydraulic fluid to the hydraulic actuator.

摘要： An outboard engine has a cowling defining an engine compartment and an outlet fluidly communicating therewith. An engine housed in the engine compartment includes an engine block and an output shaft defining an output shaft axis, an axial direction, a radial direction and a circumferential direction. An outer end thereof extends outside the engine block. A flywheel mounted thereto rotates therewith. A cover fixed with respect to the engine block defines a chamber housing the flywheel disposed axially between the engine block and the cover, and radially between the output shaft and the cover. The cover includes a channel member defining a channel between a first end and a second end fluidly communicating with the outlet. The channel member defines a cross-sectional area of the channel. A circumferentially-extending portion of the channel is continuous with the chamber and has a cross-sectional area increasing towards the second end.

摘要： A method for reversing a watercraft is disclosed. The watercraft has a reverse gate and a reverse gate actuator operatively connected to the reverse gate for moving the reverse gate between at least a stowed position and a reverse position. The method includes moving the reverse gate from the stowed position to the reverse position with the reverse gate actuator in response to receiving a reverse signal. The reverse gate actuator is controlled such that a movement speed of the reverse gate depends on at least one of a speed of the watercraft and a motor speed of a motor of the watercraft.
