Identification numbers
Record the Primary Identification (PRI-ID)
number, Craft Identification Number (CIN),
and engine serial number in the spaces pro-
vided for assistance when ordering spare
parts from a Yamaha dealer. Also record and
keep these ID numbers in a separate place in
case your watercraft is stolen.
EJU42521Primary Identification (PRI-ID) number
The PRI-ID number is stamped on a plate at-
tached inside the engine compartment. (See
page 42 for seat removal and installation pro-
cedures and page 47 for information on the
removable watertight storage compartment.)
MODEL:
GP1800-S (GP1800)
EJU36551Craft Identification Number (CIN)
The CIN is stamped on a plate attached to
the aft deck.
EJU40471Engine serial number
The engine serial number is stamped on a
plate attached to the engine unit. (See page
42 for seat removal and installation proce-
dures and page 83 for engine cover removal
and installation procedures.)

zle is changed, and the direction of the water-
craft is changed accordingly.
Since the strength of the jet thrust determines
the speed and degree of a turn, throttle must
always be applied when attempting a turn,
except at trolling speed.
This model is equipped with the Yamaha En-
gine Management System (YEMS) that in-
cludes an off-throttle steering (OTS) system.
It will activate at planing speeds should you
attempt to steer the watercraft after releasing
the throttle lever. The OTS system assists in
turning by continuing to supply some thrust
while the watercraft is decelerating, but you
can turn more sharply if you apply throttle
while turning the handlebars. The OTS sys-
tem does not function below planing speeds
or when the engine is off. Once the engine
slows down, the watercraft will no longer turn
in response to handlebar input until you apply
throttle again or you reach trolling speed.EJU41801Cooling water pilot outlets
When the engine is running, some of the
cooling water that is circulated in the engine
is discharged from the cooling water pilot
outlets.
There are cooling water pilot outlets on the
port (left) and starboard (right) sides of the
watercraft. To check for proper operation of
the cooling system, make sure that water is
being discharged from the port (left) pilot out-
let. If water is not being discharged from the
outlet, stop the engine and check the jet in-
take for clogging. (See page 92 for informa-
tion on the jet intake.)
TIP:
It will take about 60 seconds for the water
to reach the outlets after the engine is start-
ed.
Water discharge may not be constant
when the engine is running at idling speed.
If this occurs, apply a little throttle to make
sure that water discharges properly.
EJU40323Water separator
The water separator prevents water from en-
tering the fuel tank by collecting any water
that has entered the fuel tank breather hose if
the watercraft was capsized.

Multifunction information
center
The multifunction information center displays
various watercraft information.
Multifunction information center initial op-
eration
When the multifunction information center is
activated, all of the display segments come
on. After 2 seconds, the warning indicators in
the information display go off, and then the
center starts to operate normally.
If only the multifunction information center is
activated, the “WARNING” indicator light
blinks once.
TIP:
The “UNLOCK” indicator light also comes on
as part of the initial operation.
The “UNLOCK” indicator light will go off
when the engine is started.
Multifunction information center standby
state
If the multifunction information center does
not receive any operation input within 25 sec-
onds after the engine stops, the center will
turn off and enter a standby state. When the
engine is started again, the displays return totheir state before the center turned off, and
then the center starts to operate normally.
EJU35027Information display
The information display shows watercraft op-
erating conditions.
EJU43832Speedometer
The speedometer shows the watercraft
speed against water.
By switching the display units, the speed can
be shown in kilometers per hour “km/h” or
miles per hour “MPH”.

NOTICE
ECJ01311
Do not run the engine over 4000 r/min on
land. Also, do not run the engine for more
than 15 seconds without supplying water,
otherwise the engine could overheat.
Check the start switch, the engine stop
switch, and the engine shut-off switch for
proper operation. (See pages 27 to 27 for in-
formation on operating each switch.)To check the operation of the switches:
(1) If the lock mode is selected for the
Yamaha Security System setting, select
the unlock mode. (See page 26 for
Yamaha Security System setting proce-
dures.)
(2) Push the start switch to make sure that
the engine starts.
(3) As soon as the engine starts running,
push the engine stop switch to make
sure that the engine stops immediately.
(4) Restart the engine, and then pull the en-
gine shut-off cord (lanyard) to remove
the clip from the engine shut-off switch
to make sure that the engine stops im-
mediately.
EJU40102Storage compartment checks
Make sure that the storage compartments
are not damaged and that water has not col-
lected in the compartments. (See page 45 for
information on the storage compartments.)
EJU43800Fire extinguisher holder, cover, and band
checks
Make sure that the fire extinguisher holder,
cover, and band are not damaged and that
the fire extinguisher is securely held in place
