Beschreibung
Zusammenfassung:	An engine failure diagnosis system simply performs failure diagnosis of engine components, which are driven while an engine is operating, even at the time when the engine is stopped, and identifies a component that has failed and a location where a failure has occurred. The engine failure diagnosis system includes an ECM arranged to control an engine provided in an outboard motor of a watercraft. The ECM includes an actuation command section arranged to actuate engine components, which are driven while the engine is running, in a given manner, and a failure diagnosis section arranged to diagnose the presence of a failure in the engine components. The engine components of the engine are provided with actuated condition detecting sections arranged to detect a predetermined actuated condition. When the actuation command section outputs an actuation command while the engine is stopped, the engine components are actuated in a given manner.
