Abstract

In a boat propulsion apparatus including an engine control device for controlling operation of an engine, the engine control device includes a first ID storage and a second ID storage, a first ID is stored in the first ID storage beforehand, and the engine control device is communicably connected to a controller of a remote control device over a network. A signal containing a second ID is received from the controller when the engine control device and the controller are connected to the network for the first time and is stored in the second ID storage. Thus, maintenance and management of the engine are easy, and also it is possible to prevent a mischievous operation or theft of the boat propulsion apparatus.

Claims

1. A boat propulsion apparatus comprising:

an engine control device arranged to control an engine operation and including;

a first ID storage having a first ID stored therein; and

a second ID storage;

wherein

the engine control device is communicably connected to a controller of a remote control device over a network; and

a signal containing a second ID is received from the controller when the engine control device and the controller are connected to the network for the first time and is stored in the second ID storage.

2. The boat propulsion apparatus according to claim 1, wherein the engine control device is arranged to perform authentication of the second ID with the controller at a predetermined timing after the second ID is stored, and is arranged to enable remote control by the remote control device if the second ID is authenticated by the authentication.

3. The boat propulsion apparatus according to claim 1, wherein a signal is sent for the engine control device to display a warning on a display device if the second ID is not authenticated.

4. The boat propulsion apparatus according to claim 1, wherein the second ID storage is initialized by an operation of a service tool connected to the engine control device with data communication enabled.

7. A boat equipped with the boat propulsion apparatus according to claim 1.

5. A boat propulsion apparatus comprising:

an engine control device arranged to control an engine operation and including an ID storage;

wherein

the engine control device is communicably connected to a controller of a remote control device over a network; and

a signal containing an ID is received from the controller when the engine control device and the controller are connected to the network for the first time and is stored in the ID storage.

6. The boat propulsion apparatus according to claim 5, wherein operation control of the engine by the remote control device is allowed if the engine control device receives a signal containing an ID from the controller.

8. A boat equipped with the boat propulsion apparatus according to claim 5.
