FUEL GAUGE
The fuel gauge indicates the amount of fuel in the fuel tanks. The fuel gauge switch, located on the helm,
is used to switch the gauge reading to the port or starboard fuel tank. This gauge is a relative indication of
the available fuel supply and not a calibrated instrument. On Yamaha equipped boats, fuel level is read in
the speedometer.
VOLTMETER
The voltmeter displays the voltage for the battery and the charging system. The normal voltage is 11 to 12
volts with the engine(s) off and 13 to 14.5 volts with the engine(s) running.
HOUR METER
The hour meter keeps a record of the operating time for the engine.
TILT/TRIM GAUGE
The tilt/trim gauge monitors the position of the outboard engine. The upper range of the gauge indicates the
tilt, which is used for shallow water operation and trailering. The lower range indicates the trim position. This
is the range used to adjust the hull angle while operating your boat on plane. Please refer the engine owner’s
manual for more information on the operation of the outboard power tilt and trim.
ENGINE ALARMS
Most outboards are equipped with an audible alarm system mounted in the helm area that monitors selected
critical engine systems. 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.
IF THE ENGINE ALARM SOUNDS, IMMEDIATELY SHUT OFF THE ENGINE UNTIL THE
PROBLEM IS FOUND AND CORRECTED.
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 monitor aspects of the engine's fuel consumption. If you
have a fuel management system installed on your boat, please refer to the engine or fuel management manual.
INSTRUMENT MAINTENANCE
Electrical protection for instruments and ignition circuitry is provided by a circuit breaker or fuse located on
the engine. The ignition switches and all instruments, controls, etc. should be protected from the weather when
not in use. Excessive exposure can lead to gauge and ignition switch failures.
