The key fob system uses weak radio waves. The key fob system may not work in the follow-
ing situations.
For emergencies, EKS key fob floats and is water-resistant. All attempts should be made to
keep the EKS key fob dry and away from water, however. Operators are cautioned to
removed EKS key fob from pockets before entering the water.
• The key fob is placed in a location exposed to strong radio waves or other electromagnetic
noise.
• There are facilities nearby that are emitting strong radio waves (TV or radio towers, power
plants, broadcasting stations, airports, etc.).
• You are carrying or using communication equipment such as radios or mobile phones in
close proximity of the key fob.
• The key fob is in contact with or covered by a metallic object.
• Other boats equipped with a key fob system are nearby.
• The key fob is near the MFD, gauges, or a marine radio.
In such situations, move the key fob to another location and perform the operation again. If it still
does not work, operate the vehicle in emergency mode.
• Do not store the key fob in direct sunlight or in very hot locations.
• Do not drop the key fob or subject it to powerful shocks or place heavy objects on it.
• To clean the key fob, use a clean, soft, dry cloth to wipe it. Do not use cleaners, alcohol, or
other chemicals, to clean the key fob.
TIP:
• The EKS system can only be operated by a key fob that is registered as authorized in the receiver.
This is because the receiver recognizes and accepts only signals from a transmitter that is regis-
tered as authorized. If your key fob does not work, consult a Yamaha dealer.
• Replace the initial key fob battery one year after purchase, and then replace it every two years
from the second and following years.
• Dispose of the used batteries correctly according to the rules in your region.
• You can register up to six key fobs in the EKS system. For details, consult a Yamaha dealer.
• Be sure to lock the EKS when leaving the boat, or when leaving the operator’s seat if children are
nearby. Also, check that the lock indicator is turned ON.
• Repeatedly using a key fob to lock/unlock the system may cause the key fob to malfunction. When
you use a key fob for locking or unlocking the system, after you move the key fob away from the
lock indicator, wait at least one second before doing another lock or unlock operation.
• When locking/unlocking with the key fob, do not place the key close to devices possessing a mag-
netic field (magnets), as this may prevent the lock/unlock operation.
• When operating or stopping the boat, be sure to carry the key fob with you and be careful not to lose it.
• If any key fob is lost, be sure to have a Yamaha dealer delete the registration of the lost key num-
ber for security reasons.
• While operating the POWER switch or START/STOP switch, do not turn the steering wheel or per-
form any system operations at the same time, otherwise unexpected errors may occur.
• Interference from other electronic devices (radios) could affect locking and unlocking of the sys-
tem. Confirm the EKS has locked before leaving the boat. Repeat the locking/unlocking procedure
if necessary.

Engine shut-off switch
12
Engine shut-off switch
The clip must be attached to the engine shut-
off switch for the engines to run. The cord
should be attached to a secure place on the
operator’s clothing, or arm or leg. Should the
operator fall overboard or leave the helm, the
cord will pull out the clip, turning all engines
OFF. This will prevent the boat from running
away under power.
Attach the engine shut-off cord to a
secure place on your clothing, or your
arm or leg while operating. Do not attach
the cord to clothing that could tear loose.
Do not route the cord where it could
become entangled, preventing it from
functioning. Avoid accidentally pulling the
cord during normal operation. Loss of
engine power means the loss of most
steering control. Also, without engine
power, the boat could slow rapidly. This
could cause people and objects in the
boat to be thrown forward.

The key fob is provided with two cards on
which are written its factory default. Keep

TIP:
If you change the password, the factory
