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
• Transmission pressure too low
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.
