Instrumentation
It is important to monitor critical engine and boat functions while
the boat is in operation. The SmartCraft boat information system
uses gauges and/or a System View monitor screen to display the
information.
Mercury Racing requires that the following critical engine functions
be monitored:
Oil pressure
Engine RPM
Oil temperature
Water temperature
System voltage
Guardian fault messages
SmartCraft instruments display all of the above critical engine
functions, as well as others not listed. SmartCraft instruments also
display information about power train sensor faults and Guardian
activation.
Warning System
The engine's warning system includes an audible alert consisting
of a horn located in the helm harness, and the Engine Guardian
system. Do not attempt to alter or disable the warning system in
any way.
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.
