Propulsion System
NEVER EXCEED THE MAXIMUM RECOMMENDED OPERATION
RPM OF THE ENGINE. MAINTAINING MAXIMUM OR CLOSE TO
MAXIMUM RPM FOR EXTENDED PERIODS CAN REDUCE THE
LIFE OF THE ENGINE.
Speedometer
Yamaha Command Link or Command Link Plus
®
speedometers can indicate boat speed via the en-
gine pickup or an optional GPS or depth sounder
triducer, if these optional electronics are installed
in your boat. Refer to the engine gauge and elec-
tronics operating manuals for more information on
the speedometer options available for your boat.
Overheat Warning Indicator
The temperature warning indicates that the tem-
perature of the engine is too high. A sudden
increase in the temperature could indicate an ob-
structed water inlet or an impeller failure.
With Command Link instruments, the overheat
warning indicator is built into the tachometer. On
boats equipped with Command Link Plus
®
, the
overheat warning indicator is built into the LCD
display.
The warning indicator will start to blink and sound
an alarm if the engine temperature is too high.
CONTINUED OPERATION OF AN OVERHEATED ENGINE
CAN RESULT IN ENGINE SEIZURE. IF AN UNUSUALLY HIGH
TEMPERATURE READING OCCURS, SHUT THE ENGINE OFF
IMMEDIATELY. THEN INVESTIGATE AND CORRECT THE
PROBLEM.
Fuel Gauge
The fuel gauge indicates the amount of fuel in the
fuel tank.
With Command Link instruments, the fuel gauge is
built into the speedometer multi-gauge. On boats
equipped with Command Link Plus
®
, the fuel gauge
is built into the LCD Display.
The fuel indicator on the display will begin to blink
if the fuel in the tank drops too low. The system
can monitor up to 4 fuel or water tanks.
Voltmeters
The voltmeters display the voltage for the battery
and the charging system. The normal voltage is
11 to 12 volts with the engine o and 13 to 14.5
volts with the engine running.
With Command Link instruments, the voltmeter is
built into the speedometer multi-gauge. On boats
equipped with Command Link Plus
®
, the voltmeter
is built into the LCD Display.
The voltmeter display will begin to blink if the volt-
age in the battery drops too low.
Hour Meters
The hour meters keep a record of the operating
time for the engine.
Engine Tilt/Trim Gauges
The tilt/trim gauges monitor 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.
With Command Link instruments, the trim gauge is
built into the speedometer multi-gauge. On boats
equipped with Command Link Plus
®
, the trim gauge
is built into the LCD Display.
Please refer to the engine and instrument owner’s
manuals for more information on the operation of
the outboard power tilt and trim.
CONTINUED OPERATION OF AN IMPROPERLY TRIMMED MOTOR
COULD RESULT IN OVERHEATING AND POTENTIAL FAILURE
OF THE ENGINE.
Engine Alarms
All outboard engines are equipped with an audible
alarm system mounted in the helm area that moni-
tors 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 engine.
IF THE ENGINE ALARM SOUNDS, IMMEDIATELY SHUT OFF THE
ENGINE UNTIL THE PROBLEM IS FOUND AND CORRECTED.
