Instrumentation
Mercury Racing requires that the following critical engine
functions be monitored:
• Oil pressure
• Engine RPM
• Oil temperature
• Water temperature
• System voltage
• Guardian fault messages
The use of SmartCraft instrumentation will display all of the
above critical engine functions as well as others not listed.
SmartCraft instrumentation will also display information
about power train sensor faults and Guardian activation.
Warning System
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.
ENGINE GUARDIAN SYSTEM
The Engine Guardian System monitors the critical sensors on the
engine for any early indications of problems. The system responds
to a problem by emitting a continuous or intermittent horn and,
under certain circumstances, reduces engine power to provide
engine protection. When the key switch is turned "ON", the system
monitors horn beeps once to verify horn operation.
If the Propulsion Control Module (PCM) detects a fault signal from
an engine sensor, it records a fault code.
1. The horn warning can be stopped by turning the engine off. If
the horn continues to sound on restart, the system detected a
fault again. See your Mercury Marine dealer to correct the
problem.
2. On restart, if the beeping stops, see your authorized Mercury
Marine dealer to diagnose and clear the fault.
