OUTBOARD MOTOR CAPABLE OF BEING TILTED UP AND TRIMMED IN, AND MARINE VESSEL THEREWITH
An outboard motor includes a main body including a power source and a bracket to be attached to a stern of a hull. The main body is rotatable about a rotating shaft of the bracket such that an upper portion of the main body moves toward a front of a marine vessel and a lower portion of the main body moves toward a rear of the marine vessel, or such that the upper portion of the main body moves toward the rear of the marine vessel and the lower portion of the main body moves toward the front of the marine vessel. When the marine vessel is cruising, a distance from the rotating shaft to an upper end of the stern in a vertical direction of the marine vessel is equal to or longer than a distance from the rotating shaft to a propeller shaft in the vertical direction of the marine vessel.
Marine propulsion system
An outboard propulsion system comprising an engine configured to receive oil; an oil pan configured to receive oil from the engine; and an oil reservoir configured to receive oil from the oil pan and provide oil to the engine, in use.

Outboard motors having resilient mounting apparatuses
An outboard motor has a powerhead; a driveshaft housing located below the powerhead; a steering arm extending forwardly from the driveshaft housing; a steering tube extending downwardly from the steering arm; an upper mounting device that resiliently mounts the steering arm to the driveshaft housing; and a lower mounting device comprising a yoke that laterally extends from the steering tube. The yoke is clamped to the steering tube and contains port and starboard mounts that resiliently couple the steering tube to the driveshaft housing.

TRANSPORTABLE OUTBOARD MOTORS
A transportable outboard motor has a tiller which is pivotable about a lateral tilt axis into a plurality of tilt positions and also pivotable about an axial yaw axis into a plurality of yaw positions. The tiller is pivotable about the axial yaw axis into a straight-ahead position, into a port yaw position which is oriented towards the port side relative to the straight-ahead position, and into a starboard yaw position which is oriented towards the starboard side relative to the straight-ahead position. The tiller is pivotable downwardly about the lateral tilt axis from the port yaw position, and downwardly about the lateral tilt axis from the starboard yaw position. Pivoting the tiller into the plurality of yaw positions creates space for a user to manually grasp a swivel tube and thereby lift the transportable outboard motor from a rear-laydown position.

METHOD FOR MANEOUVERING A BOAT PROVIDED WITH A SINGLE DRIVE UNIT
A computer-implemented method for maneuvering a boat provided with a single drive unit, includes: Obtaining net momentum direction data indicative of a target horizontal rotational movement of the hull, triggering a series of bursts of thrust by the drive unit, said series of bursts of thrust comprising a plurality of primary bursts and a plurality of secondary bursts directed differently than the primary bursts, The primary bursts and the secondary bursts are directed such that they provide a respective longitudinal thrust component parallel to a hull longitudinal axis. The primary bursts are directed such that the longitudinal thrust components of the primary bursts act in the opposite direction with respect to the direction of the longitudinal thrust components of the secondary bursts. The primary bursts and the secondary bursts are further directed such that they jointly provide a net momentum on the hull associated with said net momentum direction data.
