摘要： A ship body control device is provided, which includes a control lever having a neutral position, and processing circuitry. When the control lever is moved during an automatic cruise, the processing circuitry executes a deceleration control from a speed of a ship body during the automatic cruise, and when the position of the control lever is in agreement with a position for changing to a manual cruise, the processing circuitry changes the automatic cruise to the manual cruise at a rotating speed of an engine according to the position for changing to the manual cruise.

摘要： A marine propulsion system includes marine propulsion devices each including a propeller shaft, an engine, an electric motor, a power transmission to transmit mechanical power to the propeller shaft from at least one of the engine and the electric motor, an electric circuit connected to the electric motor, and a controller to control the engine. The controllers in the marine propulsion devices are communicable with each other when in a communicable state. When the controller in each of the marine propulsion devices is in the communicable state, but the controller of one of the marine propulsion devices is incommunicable with any other controller of the marine propulsion devices, the incommunicable controller limits an output of the engine controlled by the incommunicable controller.

摘要： A method for controlling a propulsion operation of a propulsion unit to reach a desired speed of a marine vessel. The method comprises obtaining a target speed configuration indicating the desired speed of the marine vessel, obtaining a current speed value associated with a current speed of the marine vessel, obtaining a fill level value associated with a fill level of one or more ballast tanks of the marine vessel, and controlling the propulsion operation of the propulsion unit to reach the desired speed based on the target speed configuration, the current speed value, and on the fill level value.

摘要： A motorized watercraft includes a board and a cassette coupleable to the board. The board may be a surf board or a wakesurf board with a top surface and a bottom surface. The top surface includes a mounting space for receiving the cassette with an outer surface of the cassette in alignment with the top surface of the board and the bottom surface of the board includes an intake. The cassette includes a power source, an electric motor, an impeller, and a controller. The controller executes instructions to activate the electric motor and rotate the impeller to provide a short burst of forward thrust during operation of the watercraft in response to an input from a user. The thrust assists a user with maintaining their position on a wake during surfing or wakesurfing.

摘要： A marine propulsion device information transmitting and receiving system includes a watercraft and a server. The watercraft includes an engine and a controller to control the engine. The controller encrypts an operating time of the engine and data related to the engine with an encryption key associated with information unique to the engine. The watercraft includes a communicator to transmit the information unique to the engine, the encrypted operating time of the engine, and the encrypted data related to the engine to the server. The server decrypts the encrypted operating time of the engine and the encrypted data related to the engine with the encryption key associated with the information unique to the engine, and determines whether or not the decrypted data related to the engine are genuine based on the decrypted operating time of the engine.

摘要： A method of operating a handheld device for controlling a watercraft motor is provided. The method comprises determining whether the handheld device is operating in an anchor mode or a heading hold mode; receiving movement data when the joystick is in a non-neutral position that includes a direction of movement; generating steering command(s), with a steering command of the steering command(s) being based on the movement data; causing motor rotation based on the steering command; detecting the joystick shifting to the neutral position, with the watercraft being at a location when the joystick shifts to the neutral position; when in the anchor mode, causing the motor to cease operation proximate to the location after the joystick has shifted to the neutral position; and, when in the heading hold mode, causing the motor to continue operating so that the watercraft travels in the new heading direction after the joystick shifts.
