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.
