NOTE:
Make sure that the hood is properly secured
before operating the watercraft.
EJU31090Fuel tank filler cap
To remove the fuel tank filler cap, turn it coun-
terclockwise.
NOTE:
Make sure that the fuel tank filler cap is se-
curely closed before operating the watercraft.
EJU31120Fuel cock knob
The fuel cock supplies fuel from the fuel tank
to the carburetors.The fuel cock knob positions are explained as
follows and are shown in the illustration.
OFF:
With the fuel cock knob in this position, fuel
does not flow. Always turn the fuel cock knob
to this position when the engine is not running.
ON:
With the fuel cock knob in this position, fuel
flows to the carburetors. Turn the fuel cock
knob to this position when starting the engine
and operating the watercraft.
RES:
This indicates reserve. With the fuel cock
knob in this position, the fuel reserve is made
available. Turn the fuel cock knob to this posi-
tion if you run out of fuel while operating the
watercraft. When this occurs, refuel as soon
as possible and be sure to turn the fuel cock
knob back to “ON”!

Operation
41
(2) Swim to the rear of the watercraft and up-
right it by turning it clockwise only.
NOTE:
If the port (left) side of the capsized watercraft
is tilting up, push down on the gunwale so that
the port (left) side is down before turning the
watercraft clockwise.
CAUTION:
ECJ00520
Do not turn the watercraft over counter-
clockwise, otherwise water can enter the
carburetor and engine, which can result in
severe damage.
(3) Start the engine and operate the water-
craft to discharge any water remaining in
the engine compartment. (If the engine
does not start, see “Towing the water-
craft” on page 66 or “Submerged water-
craft” on page 67.)
NOTE:
To efficiently discharge water from the en-
gine compartment, operate the watercraft
as straight as possible and above planing
speed for at least 2 minutes.
To stabilize the watercraft when accelerat-
ing to planing speed, maintain a low center
of gravity by operating it in the kneeling po-
sition.
EJU33240Turning the watercraft
Steering control depends on the combination
of handlebar position and the amount of throt-
tle.
Water sucked in through the intake grate is
pressurized by the impeller in the jet pump. As
the pressurized water is expelled from the
pump through the jet thrust nozzle, it creates
thrust to move and steer the watercraft. The
higher the engine speed, the more thrust pro-
duced.
The amount of jet thrust, in addition to the po-
sition of the handlebars, determines how
sharply you turn.
A. More throttle produces higher thrust, so
the watercraft will turn more sharply.

Maintenance and care
60
(1) Remove all of the battery caps.
(2) If the electrolyte level is low, add distilled
water to raise it to the specified level.
(3) Set the charging rate to 1.9 ampere and
charge the battery slowly until the explo-
sive gases are discharged vigorously
from the battery cells.
To install the battery:
(1) Place the battery in the battery compart-
ment and connect the battery leads to the
battery terminals.
(2) Connect the breather hose to the battery.
(3) Secure the battery in place.
WARNING
EWJ00400
Be sure to connect the breather hose to
the battery. Fire or explosion could result
if the breather hose is damaged, obstruct-
ed, or not connected properly.
CAUTION:
ECJ00260
After installation, make sure that the bat-
tery leads are properly connected to the
battery terminals.
EJU34460Adjusting the carburetor
The carburetor is a vital part of the engine and
requires very sophisticated adjustments.Most adjustments should be left to a Yamaha
dealer who has the professional knowledge
and experience to make them. However, the
operator may adjust the trolling speed as part
of the usual maintenance routine.
CAUTION:
ECJ00170
The carburetor was set at the Yamaha fac-
tory after many tests. If the settings are
disturbed by someone who does not have
the necessary technical knowledge, poor
engine performance and damage may re-
sult.
EJU34470Adjusting the trolling speed
(1) Place the watercraft in the water.
(2) Start the engine and warm it up for 1 to 2
minutes.
(3) While using a diagnostic tachometer, turn
the throttle stop screw to adjust the en-
gine speed to specification. Turn the
throttle stop screw clockwise to increase
the engine speed or counterclockwise to
decrease the engine speed.
