An outboard motor includes an attachment attached to a hull, and a support vertically rotatably connected to the attachment and horizontally rotatably supporting an outboard motor main unit. The support includes an upper support and a lower support. The outboard motor includes a left reinforcement that includes a left upper connector connected to the upper support and a left lower connector connected to the lower support, and a right reinforcement that includes a right upper connector connected to the upper support and a right lower connector connected to the lower support. The left upper connector is located leftward of a left side of the upper support. The right upper connector is located rightward of a right side of the upper support.

An outboard motor includes an upper case located between an engine and a propulsion unit. The upper case includes case parts that are separate from each other and assembled together. The case parts include a first case part and a second case part opposing each other in a direction perpendicular or substantially perpendicular to an axis of a drive shaft.

An outboard motor includes an outboard motor body including a propulsion generator and an engine to drive the propulsion generator, a pair of clamp brackets, a swivel bracket provided between the pair of clamp brackets and rotatable in an upward-downward direction with respect to the pair of clamp brackets while supporting the outboard motor body, and an electrical wiring extending from a position between the pair of clamp brackets upward to the outboard motor body through the swivel bracket and connected to the outboard motor body.

A trim and tilt device includes: a cylinder; a piston; a rod; and a rod guide. The rod includes a first end to which the piston is fixed, and the piston includes an insertion hole to which the first end of the rod is inserted. Over an entire periphery of the rod guide, a lower end of an outer peripheral surface of the rod guide that is in contact with the inner peripheral surface of the cylinder is located closer to a second end of the rod than a lower end of a first inner peripheral surface of the rod guide where the outer peripheral surface of the rod is slidable. An upper end of an outer peripheral surface of the piston is located closer to the second end of the rod than an upper end of the insertion hole.

A drive device for a vessel includes an electric motor, driving a rotatable drive shaft; an elongate drive device housing, encapsulating the electric motor and the drive shaft; and a propeller, detachably mounted to the rotatable drive shaft. The drive device housing has an upper connection device. The upper connection device is symmetrical about a transverse axis, enabling the drive device housing to be mounted to a structure onboard the vessel in either of two longitudinal directions. The drive device and the hull of the vessel are separated from each other by using an isolation plate with a central isolation sleeve. The electric motor drives the drive shaft via an interconnected gear device encapsulated in the drive device housing or integrated as a part of the drive device housing and are arranged pivotably with respect to the tilt device housing.

A watersports boat is equipped with a trimmable drive used to generate a virtual ballast effect. Turbulence experienced by a wake rider on startup is reduced by automatically varying the drive orientation as the watersports boat comes up to speed. A pair of water channelers are located at the stern. One of the water channelers is deployed below the running surface to redirect water across centerline and improve wake shape on the selected side.

A ship propulsion system provides a first power transmission device that transmits power from an internal combustion engine to a propeller, a second power transmission device that transmits power from an electric motor to a propeller and that is mounted to the hull so as to be able to turn up and down independently from the first power transmission device, an actuator for causing the second power transmission device to turn up and down, and a control device. The control device is configured so as to be able to select a first drive mode in which the internal combustion engine is driven and the electric motor is not driven, and a second drive mode in which the internal combustion engine is not driven and the electric motor is driven. When the first drive mode is selected, the actuator is operated so that the second power transmission device turns up.
