Abstract

A watercraft propelled by an outboard motor includes an inspection system. The inspection system includes a terminal computer that conducts an inspection of an engine control device and a control unit. The computer includes a program that performs an inspection process that provides the control device with a command signal to start an inspection of the control device and that requests the control device to output a first response signal. The process determines whether the response signal is consistent with a first specified signal. The process provides the control unit with a command signal to start an inspection of the control unit and requests the control unit to output a second response signal. The process determines whether the second response signal is consistent with a second specified signal. The control device controls a throttle actuator and a shift actuator based upon the second response signal and provides the inspection system with an operating signal. The process determines whether the operating signal is consistent with the second specified signal. The computer includes an indicator panel or other display device to show the results of the determinations made by the inspection process.

Claims

1. An inspection system for a watercraft propelled by an outboard drive and having a plurality of components related to the watercraft and the outboard drive identified by distinctive part identification codes, the components being capable of outputting readable signals corresponding to the part identification codes, the inspection system comprising a first subsystem that includes a component table that stores information corresponding to the part identification codes, a second subsystem that requests the components to output the readable signals to the inspection system, and a third subsystem that compares the signals output by the components with the information stored in the component table to determine whether the signals corresponding to the part identification codes that are received from the plurality of components are consistent with the part identification codes stored on the component table, and thereby confirm whether the plurality of components correspond to a preselected list of components.

2. The inspection system as set forth in claim 1, further comprising a fourth subsystem that indicates a result of the comparison made by the third subsystem.

3. The inspection system as set forth in claim 2, further comprising an inspection device, wherein the first subsystem, the second subsystem and the third subsystem are steps of a program installed in the inspection device.

4. The inspection system as set forth in claim 3, further comprising a fourth subsystem that indicates a determination by the third subsystem, wherein the fourth subsystem is an indicating unit defined at the inspection device.

5. The system of claim 1, wherein the part identification codes are chosen from the group consisting of magnetized codes, bar codes, optical codes and electronically readable codes.

6. The system of claim 1, wherein the component table comprises a list of all components of the watercraft and the outboard drive as set forth in the specifications for the watercraft and outboard motor.

7. An inspection method for a watercraft propelled by an outboard drive and having a plurality of components related to the watercraft and the outboard drive, the plurality of components identifiable by distinctive part identification codes, the components selectably outputting readable signals corresponding to the part identification codes, the method comprising storing information corresponding to the part identification codes in a component table, causing each of the components to output a respective readable signal to an inspection system, and comparing the signals sent by the components with the information in the component table to determine whether the signals corresponding to the part identification codes that are received from the plurality of components are consistent with the part identification codes stored on the component table to thereby confirm that the plurality of components correspond to a preselected list of components.

8. The inspection method as set forth in claim 7, further comprising indicating a result of the comparison.

9. The method of claim 7, wherein the part identification codes are chosen from the group consisting of magnetized codes, bar codes, optical codes and electronically readable codes.

10. The method of claim 7, wherein the component table comprises a list of all components of the watercraft and the outboard drive as set forth in the specifications for the watercraft and outboard motor.

11. A method for inspecting a watercraft propelled by an outboard drive and having a plurality of components related to the watercraft and the outboard drive, each of the plurality of components identifiable by a distinctive part identification code, comprising:

receiving readable signals corresponding to the part identification codes from the plurality of components;

comparing the received readable signal with previously stored part identification codes on a component table; and

determining if said received readable signals are consistent with the part identification codes stored on the component table to thereby confirm that the plurality of components correspond to a preselected list of components.

12. The method of claim 11, further comprising outputting an inspection completion form.

13. The method of claim 11, further comprising outputting an abnormal condition indication if the received readable signals are not consistent with the previously stored part identification codes on the component table.
