The outboard motor 12 includes a mount frame 30. The mount frame 30 includes a shaft portion 32, and the shaft portion 32 is accommodated in the swivel case 28 so as to be rotatable about a vertical axis. The mount frame 30 has an upper end and a lower end (lower end of the shaft portion 32) fixed to a frame (not shown) constituting the main body of the outboard motor 12.

  A steering electric motor (actuator) 34 that drives the shaft portion 32 is disposed on the swivel case 28. The output shaft of the steering electric motor 34 is connected to the upper end of the mount frame 30 via the reduction gear mechanism 36.

  Primary coils 130R1 and 130L1 of first insulation mechanisms 130R and 130L are connected to power supply units 100R and 100L, respectively. On the other hand, the secondary coils 130R2 and 130L2 are connected to the boat maneuvering unit side ECU 110. As described above, the primary coils 130R1 and 130L1 and the secondary coils 130R2 and 130L2 are electrically insulated. However, when the operating current output from the power supply units 100R and 100L flows through the primary coils 130R1 and 130L1, An induced electromotive force is generated in the secondary coils 130R2 and 130L2, and an operating current is supplied to the boat maneuvering unit side ECU 110.

  In this way, by arranging the first insulation mechanisms 130R and 130L on the power supply lines 114R and 114L, the ship maneuvering unit side ECU 110 and the power supply units 100R and 100L are electrically insulated from each other while the power supply units 100R and 100L are electrically insulated. The operating current is transmitted to the maneuvering unit side ECU 110. In other words, the power handling system 102 and the power systems of the outboard motors 12R and 12L are electrically insulated (separated).

  More specifically, the secondary coil 130R2 and the secondary coil 130L2 are connected to each other on the downstream side of the first insulating mechanisms 130R and 130L, and then connected to the maneuvering unit side ECU 110 via the voltage adjustment circuit 140.

Accordingly, when the actuator control signal (current) output from the boat maneuvering side ECU 110 flows through the primary coils 132R1 and 132L1, induced electromotive force is generated in the secondary coils 132R2 and 132L2, and the outboard motor side ECUs 98R and 98L are controlled.

Therefore, when the notification unit control signals (current) output from the outboard motor side ECUs 98R and 98L flow through the primary coils 134R1 and 134L1, induced electromotive forces are generated in the secondary coils 134R2 and 134L2, and the notification unit 112 is controlled. A signal is supplied.

  That is, by disposing the third insulation mechanisms 134R and 134L on the notification unit control signal lines 124R and 124L, the notification unit 112 and the outboard motor side ECUs 98R and 98L are electrically insulated, and the outboard motor side A notification unit control signal is transmitted to the notification unit 112 from the ECUs 98R and 98L.

  In addition, electrical connection between the boat maneuvering unit 102 and the outboard motor side ECUs 98R, 98L is made in the middle of the actuator control signal lines 122R, 122L for connecting the boat maneuvering unit 102 to the outboard motor side ECUs 98R, 98L and conducting the actuator control signals. Since the second insulation mechanisms 132R and 132L are provided for transmitting the actuator control signal from the boat maneuvering unit 102 to the ECUs 98R and 98L while being insulated from each other, the power handling system of the boat maneuvering unit 102 and the outboard motors 12R and 12L is electrically connected. Is surely insulated. Therefore, even when a potential difference is generated between the boat maneuvering unit 102 and each outboard motor 12R, 12L, it is possible to more reliably prevent the operation of the apparatus from becoming unstable.

  Similarly, the notification unit 112 and the outboard are connected in the middle of the notification unit control signal lines 124R and 124L for connecting the notification unit 112 provided with the boat maneuvering unit 102 to the outboard motor side ECUs 98R and 98L and conducting the notification unit control signal. Since the third insulating mechanisms 134R and 134L that transmit the notification unit control signal from the ECUs 98R and 98L to the notification unit 112 while electrically insulating the aircraft side ECUs 98R and 98L are provided, the notification unit is provided in the boat maneuvering unit 102. Even when 112 is provided, the power control system of the marine vessel maneuvering unit 102 and the outboard motors 12R and 12L is electrically and reliably insulated, so that the operation of the apparatus can be kept stable.

  Furthermore, since the first to third insulation mechanisms 130R, 130L, 132R, 132L, 134R, and 134L are constructed of insulation transformers, the above-described effects can be obtained with a simple configuration.

  3 and 4, the actuator control signal lines include two signal lines 122R connected to the outboard motor side ECU 98R and signal lines 122L connected to the outboard motor side ECU 98L.
