DO NOT OPERATE THE ENGINE(S) IF LOW WATER PRESSURE IS INDICATED. THIS
COULD BE AN INDICATION OF A COOLING SYSTEM BLOCKAGE OR AN IMPELLER FAIL-
URE. IF LOW WATER PRESSURE IS INDICATED, SHUT THE ENGINE OFF AND INVESTI-
GATE AND CORRECT THE PROBLEM.
Oil Level Gauge
The oil level gauge indicates the amount of oil in the engine oil tank(s).
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.
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 engines. 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.
Depth Gauge
The depth gauge indicates the depth of the water below the bottom of the boat.
