We recommend instructing other occupants on proper starting and operating procedures should they need to operate the engine
in an emergency.
Accidental or unintended activation of the switch can cause any or all of the following potentially hazardous situations:
•
Sudden and unexpected loss of forward motion can throw or eject vessel occupants.
•
The loss of power will effect directional control in heavy seas, strong current, or high winds.
•
The operator can lose control of the vessel when docking.
Engine Monitoring Features
Audio Warning System
Your Cummins MerCruiser Diesel power package is equipped with an audio warning system. The audio warning system monitors
critical components and informs the operator when a malfunction has occurred. The warning system is not capable of protecting
the power package from damage caused by a malfunction.
When an electronic control system detects a recordable malfunction the audio warning system will sound to alert the operator.
The duration and type of horn sound will be dependant upon the nature of the fault condition. In the case of any horn sounding,
the user should refer to the helm displays to understand the specific situation.
For the operator to view the fault code of the malfunction indicated and any recommended actions, the power package must be
equipped with a gauge package that supports the warning system and can display fault codes.
The following instruments have screens that display fault codes:
•
VesselView
•
SmartCraft System Tachometer
•
SmartCraft System Speedometer
NOTICE
The sound from an audio warning horn indicates that a critical fault malfunction has occurred. Operating a power package with
a critical fault can damage components. If the audio warning horn emits a sound, do not continue operations unless avoiding a
hazardous situation.
If the audio warning sounds, stop the engine immediately if you are not in a hazardous situation. Investigate the cause and correct
it, if possible. If you cannot determine the cause, consult your Cummins MerCruiser Diesel Authorized Repair Facility.
VesselView
Refer to your VesselView operations manual for detailed engine monitoring information.

Typical system tachometer fault code display
After pressing "MODE," a blinking "AL" also appears in the upper right corner of each menu on the digital display screen to signify
an active fault. A major fault is also accompanied by an audio warning.
To view the active faults, press "MODE" until you reach the total engine hours screen. In the event of an active fault code, total
engine hours are displayed for 30 seconds after key‑on. After 30 seconds, the digital display screen outputs the active fault codes
in 3‑second intervals.
