Section 2 - Getting to Know Your Power Package
Page 14 90-8M0069751 eng APRIL 2012
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 Mercury Marine 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 dependent 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 Mercury Diesel authorized repair facility.
VesselView
Refer to your VesselView operations manual for detailed engine monitoring information.
System Tachometer or Speedometer
The LCD on the system tachometer, if equipped, displays active fault codes. To indicate an active fault code is present the
following screen appears on the tachometer display.

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.
