摘要： A control system for a watercraft includes an outboard motor, a tilt mechanism, a sensor, and a computer. The outboard motor is attached to the watercraft. The tilt mechanism includes a tilt shaft and a tilt actuator to cause the outboard motor to pivot about the tilt shaft. The tilt mechanism is attached to the watercraft and supports the outboard motor such that the outboard motor is pivotable about the tilt shaft. The sensor is operable to detect tilt status data indicating a status of the tilt mechanism. The computer is configured or programmed to store a decision logic to determine whether or not a malfunction or trouble of the tilt mechanism has occurred, obtain the tilt status data, and determine whether or not the malfunction or trouble of the tilt mechanism has occurred based on the tilt status data with reference to the decision logic.

摘要： A drive unit for propulsion and trim control of a marine vessel. The drive unit extends in use from the vessel along a vertical axis to a base plane normal to the vertical axis, and spanned by orthogonal longitudinal and lateral axes. The drive unit includes a first propulsion unit and a second propulsion unit arranged separated along the lateral axis and intersected by the base plane. The first propulsion unit and the second propulsion unit are jointly rotatable about the vertical axis, where the first propulsion unit and the second propulsion unit are individually rotatable about the lateral axis.

摘要： An operation device includes a lever, a holder rotatably supporting the lever, a rotation restriction mechanism restricting a rotation range of the lever to the rotation range including a forward movement operation range, a backward movement operation range, and a neutral position, and a lever holding mechanism holding the lever at the neutral position. The lever includes a base portion rotatable supported by the holder, and an operation portion being movably connected to the base portion with respect to the base portion in an extending direction of the operation portion. The lever holding mechanism holds the lever at the neutral position so as not to be rotatable when the operation portion moves toward one side in the extending direction, and brings the lever into a rotatable state from the neutral position when the operation portion moves toward the other side in the extending direction.

摘要： A watercraft maneuvering system includes an actuator having a function of generating a propulsion force of a watercraft and a function of causing the watercraft to generate a moment, an operation unit configured to receive an input operation of a watercraft operator, and a watercraft control device configured to operate the actuator. When the operation unit has received an input operation for stopping an operation of the actuator while the watercraft control device is operating the actuator, the watercraft control device operates the actuator without any need for the operation unit to receive the input operation for at least one function of the actuator generating the propulsion force in an opposite direction to a direction of an inertial force occurring in the watercraft and causing the watercraft to generate the moment in an opposite direction to a direction of a moment of inertia occurring in the watercraft.

摘要： In a control device for a battery of a marine vessel, a first value indicating either a voltage or a power storage amount of a main battery to supply electric power to start the engine is acquired. When the first value that has been acquired is smaller than a first threshold value, at least one of a prohibition of a transition to a motor drive mode in which a propeller is driven by using at least a motor regardless of an operation mode that is designated and a prohibition of charging a load battery is performed, and the engine is caused to rotate to charge the main battery.

摘要： This ship maneuvering device causes a ship having at least one propulsion device mounted thereon to travel along a scheduled course. The ship maneuvering device is provided with a control unit. The control unit acquires an azimuth deviation between an actual bow azimuth, which is the current bow azimuth of the ship, and a target bow azimuth of the ship, and, on the basis of the azimuth deviation, generates a thrust command that indicates the thrust with which the ship is to be propelled. In the case where the azimuth deviation is equal to or greater than a prescribed value, the control unit generates a thrust command such that causes the speed of the ship is reduced below an actual speed which is the current speed of the ship.

摘要： A marine propulsion system includes a marine drive having an electric motor powerhead, at least one marine battery, at least a first connection cable having a connector configured to removably connect to a drive port on a housing of the marine drive, and an interlock circuit. The interlock circuit is configured to provide a completed circuit when the at least one battery and the marine drive are connected via at least the first connection cable, wherein the interlock circuit is independent from a power circuit delivering power from the at least one marine battery to the marine drive. The at least one battery is configured to identify whether the interlock circuit is completed and to control an internal disconnect to connect to the power circuit when the interlock circuit is completed and to disconnect from the power circuit when the interlock circuit is opened.
