Abstract

An outboard motor is presented that includes a control unit to control operation of an internal combustion engine and automated components of the motor. An array of indicators is associated with the control unit directly on an external or visible surface thereof or integrally formed therewith. The indicators may be independently activated to convey diagnostic information regarding engine operation. The control unit controls activation of the indicators in such a manner such that different diagnostic data is conveyed depending upon whether the engine is in an operating or starting mode.

Claims

1. An outboard motor comprising:

an internal combustion engine having a vertical crankshaft;

a mid-section disposed below the internal combustion engine and supporting the internal combustion engine, the mid-section being configured for mounting on a transom of a watercraft;

a lower unit disposed below the mid-section, the lower unit including a propeller driven by the internal combustion engine and configured to propel the watercraft; and

a set of fault indicators mounted directly to a portion of the internal combustion engine, wherein the set of indicators provides at least one form of feedback to a user regarding at least an operational condition at engine start-up.

2. The outboard motor of claim 1 wherein the at least one form of feedback includes a visual feedback.

3. The outboard motor of claim 2 wherein the set of indicators is configured to illuminate at engine start-up if no engine fault conditions are deemed present.

4. The outboard motor of claim 3 wherein the set of indicators includes a separate indicator to indicate each of the following at engine start-up:

kill switch activation;

sensed crankshaft position;

acceptable charging level attained; and

acceptable drive gear position.

5. The outboard motor of claim 4 wherein one indicator is configured to change condition if the drive gear position is in neutral at start-up.

6. The outboard motor of claim 2 further comprising a control unit mounted to the internal combustion engine and wherein the multi-mode set of fault indicators is mounted to the control unit in a manner visible to a user when only a top cover of the outboard motor is removed.

7. The outboard motor of claim 6 wherein the control unit includes a recordable medium accessible by a service technician and configured to maintain a history of any fault indicator.

8. The outboard motor of claim 2 wherein the internal combustion engine is a two-stroke internal combustion engine.

9. The outboard motor of claim 2 further comprising a battery to supply a voltage to a plurality of electronic components.

10. The outboard motor of claim 2 wherein the internal combustion engine is a rope-start engine.

11. The outboard motor of claim 1 wherein the set of indicators provides a form of feedback to a user regarding both an operational condition at start-up and an operational condition during running.

12. The outboard motor of claim 11 wherein the set of indicators includes a separate indicator to indicate each of the following during engine running:

charging system malfunction;

injection/ignition system malfunction;

sensor system malfunction; and

engine lubrication/engine temperature malfunction.

13. An outboard motor comprising:

an internal combustion engine having a vertical crankshaft;

a mid-section disposed below the internal combustion engine and supporting the internal combustion engine, the mid-section being configured for mounting on a transom of a watercraft;

a lower unit disposed below the mid-section, the lower unit including a propeller driven by the internal combustion engine and configured to propel the watercraft; and

at least one fault indicator mounted to a portion of the outboard motor, wherein the at least one fault indicator provides at least one form of feedback to a user regarding at least an operational condition at engine start-up.

14. The outboard motor of claim 13 wherein the at least one fault indicator is a multi-mode set of fault indicators.

15. The outboard motor of claim 13 wherein the at least one form of feedback includes a visual feedback.

16. The outboard motor of claim 15 wherein the at least one indicator is configured to illuminate at engine start-up if no engine fault conditions are deemed present.

17. The outboard motor of claim 16 wherein the at least one indicator includes a separate indicator to indicate each of the following at engine start-up:

kill switch activation;

sensed crankshaft position;

acceptable charging level attained; and

acceptable drive gear position.

18. The outboard motor of claim 17 wherein one of the at least one indicators is configured to change condition if the drive gear position is in neutral at start-up.

19. The outboard motor of claim 15 further comprising a control unit mounted to the internal combustion engine and wherein the fault indicator is mounted to the control unit in a manner visible to a user when only a top cover of the outboard motor is removed.

20. The outboard motor of claim 19 wherein the control unit includes a recordable medium accessible by a service technician and configured to maintain a history of the fault indicator.

21. The outboard motor of claim 15 wherein the internal combustion engine is a two-stroke internal combustion engine.

22. The outboard motor of claim 15 further comprising a battery to supply a voltage to a plurality of electronic components.

23. The outboard motor of claim 15 wherein the internal combustion engine is a rope-start engine.

24. The outboard motor of claim 13 wherein the at least one indicator provides a form of feedback to a user regarding both an operational condition at start-up and an operational condition during running.

25. The outboard motor of claim 24 wherein the at least one indicator includes a separate indicator to indicate each of the following during engine running:

charging system malfunction;

injection/ignition system malfunction;

sensor system malfunction; and

engine lubrication/engine temperature malfunction.
