Engine Alarms
Most outboards are equipped with an audible
alarm system mounted in the helm area to
monitor selected critical engine systems and
functions. The alarm will sound if one of these
systems begins to fail. Refer to the engine
owner’s manual for information on the alarms
installed with your engines.
CAUTION
!
If an engine alarm sounds, shut off the
engine, investigate the problem and
correct it.
Fuel Management
Fuel management systems are standard
equipment with some outboard engines.
On Yamaha engines, the fuel management
gauge is a multifunction gauge used to mon-
itor fuel consumption of the engines. If your
boat is equipped with this system, refer to the
engine or fuel management manual.
Instrument Maintenance
Electrical system, instruments and ignition
circuitry are protected by a circuit breaker
or fuse located on the engine. The ignition
switches and all instruments, controls, etc.,
must be protected from the weather when
not in use. Excessive exposure can lead to
gauge and ignition switch failures.
