An electric propulsion device includes a duct having a cylindrical shape and that includes a stator. A rim includes a rotor rotatable relative to the duct, and a plurality of fins. A bracket supports the duct so as to allow the duct to turn about a turning axis that intersects with the rotation axis of the rim, and a turning actuator that integrally turns the duct and the rim. The turning actuator is fixed to the bracket, and the duct is turnable relative to the bracket.

Electric propulsion device

A marine propulsion device includes a power source, a steering handle, and an accelerator grip that moves with respect to the steering handle. A movement region of the accelerator grip includes a forward movement rotation region, a reverse movement rotation region and an axis movement region. In the forward movement rotation region, the accelerator grip is operated to rotate so as to obtain a drive force in a forward movement direction. In the reverse movement rotation region the accelerator grip is operated to rotate so as to obtain a drive force in a reverse movement direction. The axis movement region is provided between the forward movement rotation region and the reverse movement rotation region. In the axis movement region, the accelerator grip is moved in the extensional direction of a rotation axis.

Marine propulsion device

A boat maneuvering system includes a power source, a first operating device configured to operate the power source, a first controller configured to control the power source, a second controller configured to accept an operation instruction input from the first operating device and to output a control signal to the first controller, a first electric power line that connects the power source to a battery to convey electric power therebetween, a second electric power line that connects the second controller to the battery to convey electric power therebetween, a communication path that connects the first controller and the second controller to convey a signal therebetween, and a signal conversion portion provided on the communication path to electrically separate the first and second controllers.

Boat maneuvering system

A boat maneuvering system includes a power source, a first controller that controls the power source, a display device that has a touch panel function and displays an operation screen configured to operate the movement of a boat, and a second controller that is communicatively connected to the first controller and enables an operation of the boat through the operation screen when detecting a plurality of operations on the display device simultaneously.

A boat maneuvering system, including a first power source having a first controller, a first operating device having a second controller configured to receive a first operation instruction and to output a first control signal for controlling the first power source, a second power source provided separately from the first power source, and a second operating device provided separately from the first operating device for operating the first and second power sources. The second operating device includes a third controller provided on a communication path connecting the first and second controllers, the third controller being configured to receive the first control signal, generate a second control signal, and output the second control signal to the first controller, and to receive a second operation instruction via the second operating device, generate a third control signal, and output the third control signal to the second power source.
