Voltmeter
The voltmeter displays the voltage for the battery and the charging system. The normal voltage is
11 to 12 volts with the engines 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 trailering and shallow water operation. 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 the gallons per hour,
miles per gallon, total gallons used and engine synchronization. If you have a fuel management
system installed on your boat, please refer to the engine or fuel management manual for information
on that system.
Compass
The compass is on top of the helm. To adjust the compass for your area, read the instructions on
“Compass Compensation” given to you in the literature packet. The compass cannot be adjusted
accurately at the factory as it must be compensated for the influence of the electrical equipment and
electronics unique to your boat. Therefore, the compass should be adjusted by a professional after
the electronics and additional electrical accessories are installed and before operating the boat.
Instrument Maintenance
Electrical protection for instruments and ignition circuitry is provided by a set of circuit breakers
located near the main battery switch and on each engine. The ignition switches should be sprayed
periodically with a contact cleaner/lubricant. 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 difficulties.
