Abstract

In an apparatus for preventing theft of plural, such as two, outboard motors (12F, 12S) adapted to be mounted on a boat, each of the outboard motors having an engine (16F, 16S), an engine controller (24F, 24S), and an authenticator (26F, 26S) that acquires ID information (A, B) from an electronic key (30F, 30S) when the key is brought close thereto by an operator, and gives permission to the engine controller to start the engine when the acquired ID information corresponds with the authentication ID information, and communicates with the engine controller of other outboard motor to notify that the permission to start the engine was given, thereby enabling the operator to easily start the outboard motors installed on one boat and having their respective authenticators.

Claims

1. An apparatus for preventing theft of outboard motors adapted to be mounted on a stern of a boat, each of the outboard motors having an internal combustion engine and an engine controller for controlling operation of the engine, comprising:

an authenticator that is installed in each of the outboard motors and that acquires ID information from an electronic key when the key is brought close thereto by an operator, compares the acquired ID information with authentication ID information, and gives permission to the engine controller to start the engine when it is determined that the acquired ID information corresponds with the authentication ID information,

wherein the authenticator communicates with the engine controller of other of the outboard motors to notify that the permission to start the engine was given and wherein the engine controller and the authenticator of each of the outboard motors are connected by a first wire and each of the first wire is connected by a second wire such that the authenticator communicates with the engine controller of other of the outboard motors through the second wire.

2. The apparatus according to claim 1, wherein the authenticator communicates with other of the outboard motors such that the authenticator compares the acquired ID information with authentication ID information of the other outboard motor and gives the permission to the engine controllers to start the engines when it is determined that the acquired ID information corresponds with the authentication ID information.

3. A method for preventing theft of outboard motors adapted to be mounted on a stern of a boat, each of the outboard motors having an internal combustion engine and an engine controller for controlling operation of the engine, wherein the engine controller and the authenticator of each of the outboard motors are connected by a first wire and each of the first wire is connected by a second wire such that the step of communicating communicates with the engine controller of other of the outboard motors through the second wire,

comprising the steps of:

acquiring ID information from an electronic key when the key is brought close thereto by an operator,

comparing the acquired ID information with authentication ID information,

giving permission to the engine controller to start the engine when it is determined that the acquired ID information corresponds with the authentication ID information, and

communicating with the engine controller of other of the outboard motors to notify that the permission to start the engine was given.

4. The method according to claim 3, wherein the step of communicating communicates with other of the outboard motors such that the step of comparing compares the acquired ID information with authentication ID information of the other outboard motor and the step of giving permission gives the permission to the engine controllers to start the engines when it is determined that the acquired ID information corresponds with the authentication ID information.
