EMU26493
Digital tachometer
The tachometer shows the engine speed
and has the following functions.
All segments of the display will light momen-
tarily after the main switch is turned on and
will return to normal thereafter.
TIP:
The water separator and engine trouble-alert
indicators only operate when the engine is
equipped with the appropriate functions.
EMU36050
Tachometer
The tachometer displays engine speed in
hundreds of revolutions per minute (r/min).
For example, if the tachometer display reads
“22” then the engine speed is 2200 r/min.
EMU26621
Trim meter
This meter shows the trim angle of your out-
board motor.
●Memorize the trim angles that work best
for your boat under different conditions.
Adjust the trim angle to the desired usingthe power trim and tilt switch.
●If the trim angle of your motor exceeds the
trim operating range, the top segment on
the trim meter display will blink.
EMU26651
Hour meter
This meter shows the number of hours the
engine has been run. It can be set to show
the total number of hours or the number of
hours for the current trip. The display can
also be turned on and off.
To change the display format, press the
“ ” (mode) button. The display can show
total hours or trip hours, or turn off.
To reset the trip hours, simultaneously press
the “ ” (set) and “ ” (mode) buttons for
more than 1 second while the trip hours are
displayed. This resets the trip counter to 0
(zero).
The total number of hours the engine has
been run cannot be reset.

Low oil pressure-alert indicator
If oil pressure drops too low, the alert indica-
tor will start to blink. For further information,
see page 47.
NOTICE
ECM00022
●Do not continue to run the engine if the
low oil pressure-alert indicator is on
and the engine oil level is lower. Seri-
ous engine damage will occur.
●The low oil pressure-alert indicator
does not indicate the engine oil level.
Use the oil dipstick to check the re-
maining oil quantity. For further infor-
mation, see page 53.
EMU26583
Overheat-alert indicator
If the engine temperature rises too high, the
alert indicator will start to blink. For further in-
formation on reading the indicator, see page
47.
NOTICE

Do not continue to run the engine if the
overheat-alert indicator is on. Serious en-
gine damage will occur.
EMU26602
Digital speedometer
This gauge shows the boat speed and other
information.
All segments of the display will light momen-
tarily after the main switch is turned on and
will return to normal thereafter.
EMU36061
Speedometer
The speedometer displays km/h, mph, or
knots, according to operator preference. Se-
lect the desired units of measurement by set-
ting the selector switch on the back of the

EMU26713
Fuel gauge
Eight segments indicate the fuel level. When
all segments are showing, the fuel tank is
full.
The fuel level reading can be inaccurate due
to the position of the sensor in the fuel tank
and the attitude of the boat in the water. Op-
eration with bow-up trim or continuous turn-
ing can give false readings.
Do not adjust the selector switch for fuel sen-
sor. Incorrectly setting the selector switch on
the gauge will give false readings. Consult
your Yamaha dealer on how to correctly set
the selector switch. NOTICE: Running out
of fuel can damage the engine.

miles depending upon the unit of measure-
ment selected for the speedometer.

(set) and “ ” (mode) buttons at the same
time.
The trip distance is kept in memory by bat-
tery power. The stored data will be lost if the
battery is disconnected.

alert indicators. For more details on setting
meters or changing indicator systems, see
the attached operation manual.
EMU36103
Command link multifunction 
tachometers
The tachometer shows the engine revolu-
tions per minute. It has functions of trim
meter, adjusting trolling speed, cooling wa-
ter/engine temperature display, battery volt-
age display, total hour/trip hour display, oil
pressure display, water detection alert, en-
gine trouble alert, and periodic maintenance
notification. If the cooling water pressure
sensor is installed, the unit can also show the
cooling water pressure display. However,
even if the cooling water pressure sensor is
not installed, the cooling water pressure dis-
play can be shown by connecting an optional
sensor to the unit. For the optional sensor,
consult your Yamaha dealer. The tachome-
ter unit is available in round or square types.
Check your tachometer unit type.

Start-up checks
Place the remote control lever / gear shift le-
ver in neutral and turn the main switch to
“ ” (on). After all the displays come on and
the total hour display comes on, the gauge
will change to normal operation. If the buzzer
sounds and the water separator-alert indica-
tor blinks, consult your Yamaha dealer im-
mediately.
TIP:
To stop the buzzer, press the “ ” (set) or
“ ” (mode) button.
EMU37690
Adjusting trolling speed
You can adjust the trolling speed randomly
by increasing or decreasing it approximately
50 r/min. When in the trolling speed setting
mode, the display switches to the normal dis-
play when the engine speed is increased
(within 3000 r/min) using the throttle. When
the throttle is closed, the display returns tothe trolling speed setting mode. For details,
see the attached operation manual.
TIP:
●Trolling is affected by currents and other
operating conditions and may differ from
the actual engine speed.
●The default engine idle speed is reset au-
tomatically when the display is switched to
the normal display. The default engine idle
speed is also reset automatically when the
engine is turned off or when the engine
speed exceeds 3000 r/min.
●When warming up a cold engine, the troll-
ing speed cannot be decreased below the
specified engine idle speed.

Command link multifunction 
speed & fuel meters
The speed & fuel meter unit shows the boat
speed and has the functions of fuel meter, to-
tal fuel consumption display, fuel economy
display, fuel flow display, and system voltage
display. The chosen display is selected by
using the “ ” (set) and “ ” (mode) but-
tons as described in this section. If the speed
sensor is installed, the unit can also show the
trip display. However, even if the speed sen-
sor is not installed, the trip display can be
shown by connecting an optional sensor to
the unit. In addition, if optional sensors are
connected to the unit, water surface temper-
ature display, depth display, and clock will
also be available. For the optional sensors,
consult your Yamaha dealer.
The speed & fuel meter unit is available in
round or square types. Check your speed &
fuel meter unit type for operation information.
After the main switch is first turned on, all the
displays come on as a test. After a few sec-
onds, the gauge will change to normal oper-
ation.
