Audio Warning System
Your Mercury MerCruiser power package may be equipped with an Audio Warning System. The Audio Warning System will not
protect the engine from damage. It is designed to warn the operator that a problem has occurred.
The audio warning system will sound with a continuous horn if one of the following occurs:
•
Engine oil pressure too low
•
Engine temperature too hot
•
Seawater pressure too low
The audio warning system will sound with an intermittent beeping if the following occurs:
•
Transmission fluid temperature too hot
NOTICE
A continuous horn indicates a critical fault. Operating the engine during a critical fault can damage components. If the
warning horn emits a continuous beep, do not operate the engine unless avoiding a hazardous situation.
If the alarm sounds, stop the engine immediately. Investigate cause and correct it, if possible. If the cause cannot be
determined, contact your authorized Mercury MerCruiser dealer.
Testing The Audio Warning System
1. Turn the ignition switch to the "ON" position without cranking the engine.
2. Listen for the audio alarm. The alarm will sound if the system is functioning correctly.
