General information
Safety while working To prevent an accident or injury and to pro-
vide quality service, observe the following
safety procedures. Rotating part • Hands, feet, hair, jewelry, clothing, personal
flotation device straps, and so on, can
become entangled with internal rotating
parts of the engine, resulting in serious
injury or death.
Keep the top cowling installed whenever
possible. Do not remove or install the top
cowling when the engine is running.
Only operate the engine with the top cowl-
ing removed according to the specific
instructions in the manual. Keep hands,
feet, hair, jewelry, clothing, personal flota-
tion device straps, and so on, away from
any exposed moving parts. Hot part During and after operation, engine parts are
hot enough to cause burns. Do not touch any
parts under the top cowling until the engine
has cooled. Electric shock Do not touch any electrical parts while start-
ing or operating the engine. Otherwise, shock
or electrocution could result.
Handling of gasoline Gasoline is highly flammable. Keep gaso-
line and all flammable products away from
heat, sparks, and open flames.
Gasoline is poisonous and can cause injury
or death. Handle gasoline with care. Never
siphon gasoline by mouth. If you swallow
some gasoline, inhale a lot of gasoline
vapor, or get some gasoline in your eyes,
see your doctor immediately. If gasoline
spills on your skin, wash with soap and
water. If gasoline spills on your clothing,
change your clothes. Ventilation Gasoline vapor and exhaust gas are
heavier than air and extremely poisonous. If
gasoline vapor or exhaust gas is inhaled in
large quantities, it may cause loss of con-
sciousness and death within a short time.
When test running an engine indoors (for
example, in a water tank) make sure to do
so where adequate ventilation can be main-
tained.

Self-protection Protect your eyes by wearing safety
glasses or safety goggles during all opera-
tions involving drilling and grinding, or when
using an air compressor.
Protect your hands and feet by wearing pro-
tective gloves and safety shoes when nec-
essary. Working with crane Outboard motors weighing 18.0 kg (39.7 lb)
and over must be carried by a crane.
Use the wire ropes of adequate strength,
and lift up the outboard motor using the
three-point suspension.
If the outboard motor does not have three
or more points to be suspended, support it
using additional ropes, or the like, so that
the outboard motor can be lifted and carried
in a stable manner.
Part, lubricant, and sealant Use only genuine Yamaha parts, lubricants,
and sealants, or those recommended by
Yamaha, when servicing or repairing the out-
board motor. Handling of sealant Wear protective gloves to protect your skin,
when using the sealants.
See the material safety data sheet issued
by the manufacturer. Some of the sealants
may be harmful to human health. Special service tool Use the recommended special service tools
to work safely, and to protect parts from dam-
age.

General information
Tightening torque When tightening nuts, bolts, and screws, fol-
low the tightening instructions provided
throughout the manual. If the tightening order
is not specified, tighten the large sizes first,
and then tighten the small sizes, starting from
the center and moving outward. Non-reusable part Always use new gaskets, seals, O-rings, cot-
ter pins, and so on, when installing or assem-
bling parts. Disassembly and assembly Use compressed air to remove dust and dirt
during disassembly.
Apply specified grease to the contact sur-
faces of moving parts before assembly.
Check that moving parts operate normally
after assembly.

Digital Electronic Control The new Digital Electronic Control starts and stops the engine using a CAN signal, which allows the
operator to start the engine with a single touch co mbining it with an outboard motor capable of one-
touch engine starts.
For multi-engine applications, attaching an ALL engine start/stop button allows the operator to start
all outboard motors.
Unlike existing Digital Electronic Controls, the neutra l position of the control lever is detected only by
the LPS.
This system is compatible with the Command Link Plus network so that it can be equipped with the
Command Link Plus Multifunction Color Gauge.
The new Digital Electronic Control is also compatible with Command Link network. However, the
Command Link Plus network cannot be used with the Command Link network simultaneously.
Switching the engine starter circuit will be require d when using outboard motors compatible with
existing Digital Electronic Controls in combination with a new Digital Electronic Control (except for
single station models). The default setting is to use the engine starter circuit of outboard motors
compatible with the new Digital Electronic Control.

Technical feature and description
Authorization system The Digital Electronic Control ECM has its authentication ID recognized by the engine ECM, and the
Digital Electronic Control ECM verifies the engi ne ECM using the authentication ID when the system
is activated. If the authentication ID does not match, the engine cannot be started.
Reset the authentication ID on the engine ECM using YDIS Ver. 1.33 to allow the engine ECM to
recognize the Digital Electronic Control ECM agai n. Once the engine ECM is reset, connect the Dig-
ital Electronic Control ECM to the engine ECM, and the engine ECM will recognize the authentica-
tion ID of the Digital Electronic Control ECM auto matically, allowing the Digital Electronic Control
ECM to take control of the engine operation.
When the engine ECM and Digital Electronic Control ECM authentication ID do not match, neither
the active indicator nor the alert indicator comes on.

Engine start and stop control Under the new Digital Electronic Control system, the Digital Electronic Control ECM sends an
engine start and stop request that causes the engine to start or stop.
When the engine start switch or engine start/stop button is used to send an engine start and engine
stop signal, the Digital Electronic Control ECM sends an engine start and stop signal to the engine
ECM based on the engine start and stop status.
The engine ECM starts or stops the engine, depending on its current state.
When starting the engine using the ALL engine start/stop button, an engine start signal is sent to
the engine ECM in order of PORT and STBD for twin engine installations, and to PORT, center and
STBD in order for triple engine installations.
Pushing the ALL engine start/stop button when any of the outboard engines are stopped causes the
Digital Electronic Control ECM to send a stop request to all engine ECMs.

Technical feature and description
Shift-in prevention control in high-speed range When the control lever is moved quickly, for example, from the fully open F position a directly to the
fully open R position while the engine speed is higher than the predetermined level (approximately
1500 r/min), the Digital Electronic Control ECM prevents gear shift until the engine speed is
decreased to below the level for which the gear shift is enabled.
Shifting to neutral starts once the control le ver is moved beyond the gear shift enabling threshold b.
The throttle valve is kept at fully closed position even after the control lever reaches notch point R.
The actual gearshift is kept at N by the engine ECM until the engine speed reaches point c where
the gearshift is enabled.
Once the engine speed is decreased to 1500 r/min, gear shift operation to R starts at point c. After
gear shift position d, the throttle opening is controlled to the position corresponding to the Digital
Electronic Control lever position. A similar contro l process occurs when the control lever is moved
quickly directly from the fully open R position to the fully open F position.

Synchronizing control This control is used to synchronize engine speeds for twin outboard motor installations. When the
relative positioning of the control levers for the tw in type stays within the synchronizing control range
for the specified period, the engine speed of the ST BD outboard motor is synchronized with that of
the PORT outboard motor.
The same applies to the triple outboard motor installation. Under synchronizing control, the center
outboard motor runs at the same speed as the PORT outboard motor. The synchronization control
is canceled once the angular difference between the two control levers is out of the predetermined
control range.

dance with the input from the switches which are installed at the main station, sub station, and the
bottom cowling respectively.
The following table shows the PTT operations corresponding to the independent or simultaneous

cowling from striking the motor well on the boat when the outboard motor is fully tilted up. The tilt
limit position set by this function ranges from th e maximum tilt angle to approximately minus 4°–17°.
The tilt limiter for PORT, STBD, and center outboard motors needs to be configured separately.
The tilt limit position is set using YDIS (ver. 1.33 or later). See “Setting the tilt limiter (for applicable
