Yamaha Command Link Plus

speedometers can
indicate boat speed via the engine pickup or an
optional GPS or depth sounder triducer, if these
options are installed in your boat. Refer to the
engine gauge and electronics 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
obstructed water inlet or an impeller failure. On
Yamaha engines the overheat warning indicator
is built into the LCD display. It will start to blink
and sound an alarm if the engine temperature is
too high.
CAUTION
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 tanks. On boats equipped with Yamaha
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 for each engine. The
normal voltage is 11 to 12 volts with the engines
off and 13 to 14.5 volts with the engines running.
The Yamaha engine voltmeter is built into the LCD
display. It will begin to blink if the voltage in the
battery drops too low.
Hour Meters
The hour meters keep a record of the operating
time for each engine.
Engine Tilt/Trim Gauges
The tilt/trim gauges monitor the position of each
outboard engine. The upper range of the gauge
indicates the tilt, which is used for trailering and
shallow water operation. The lower range indi-
cates the trim position. This is the range used to
adjust the hull angle while operating your boat on
plane. The Yamaha engine trim indicator is built
into the LCD display. Please refer to the engine
and Command Link Plus
®
owner’s manuals for
more information on the operation of the outboard
power tilt and trim.
Engine Alarms
All 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.
CAUTION
IF THE ENGINE ALARM SOUNDS, IMMEDIATELY SHUT OFF THE
ENGINE UNTIL THE PROBLEM IS FOUND AND CORRECTED.
Fuel Management
Fuel management systems are standard equip-
ment with some outboard engines. On Yamaha
engines, the fuel management gauge is built into
the Command Link Plus
®
display and can moni-
tor miles per gallon, total gallons used and total
gallons remaining.
If you have a fuel management system installed
on your boat, please refer to the engine or fuel
management manual for detailed information on
that system.
