Speedometer
The speedometer indicates the speed of the
boat in miles per hour. Most speedometers
measure the water pressure against a small
hole in a pickup tube located in the engine
lower unit or mounted on the bottom of the
transom.
Temperature Warning
The temperature warning indicates the tem-
perature of the engine. A sudden increase in
the temperature could indicate an obstructed
water inlet or an impeller failure.
Fuel Gauge
The fuel gauge indicates the amount of fuel
in the fuel tanks. This gauge is a relative
indication of the available fuel supply and
not a calibrated instrument.
Voltmeter
The voltmeter displays the voltage for the
battery and the charging system. The nor-
mal 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 oper-
ating 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 audi-
ble alarm system mounted in the helm area
that monitors selected critical engine sys-
tems. 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.
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 mon-
itor aspects of the engine's fuel consump-
tion. If you have a fuel management system
installed on your boat, please refer to the
engine or fuel management manual.
! CAUTION
Never exceed the maximum recom-
mended operation rpm of the engine.
Maintaining maximum or close to
maximum, rpm for extended periods
can reduce the life of the engine.
! CAUTION
Continued operation of an overheated
engine can result in engine seizure. If
an unusually high temperature read-
ing occurs, shut the engine off imme-
diately. Then investigate and correct
the problem.
! CAUTION
If the engine alarm sounds, immedi-
ately shut off the engine until the
problem is found and corrected.
