Switches
Check the start switch 1, the engine stop
switch 2, and the engine shut-off switch 3
for proper operation.
To check these switches, place the water-
craft in the water to provide adequate cooling.
Start the engine, and then pull the engine
shut-off cord5 to remove the clip4 from
the engine shut-off switch. Verify that the
engine stops immediately. (See pages 2-8 to
2-9 for information on proper operation of the
start switch, the engine stop switch and the
engine shut-off switch.)

lets while the engine is running and the
watercraft is in the water.

2. Turn the fuel cock knob to the “ON” posi-
tion.
NOTE:@ Before starting the watercraft, after it has
been sitting, remove the fuel tank filler cap
to release any built-up pressure in the tank
due to fuel expansion.
@
3. Attach the clip 1 to the engine shut-off
switch 2. Also, attach the engine shut-
off cord 3 to your left wrist.
WARNING@ Check that the engine shut-off cord is not
frayed or broken, and keep it free from
the handlebars so the engine stops if the
operator falls off. The engine shut-off
cord may not pull free if wrapped around
the handlebars when the operator falls
off, allowing the watercraft to continue to
run and cause an accident.
@
NOTE:@ It is not possible to start the engine with the
clip removed from the engine shut-off
switch.
@
4. Move the choke lever all the way in the
direction of the arrow to start a cold
engine.
NOTE:@ The choke should not be used when the
engine is warm.

sion could result in severe injury or
death.

turn the water supply on until water flows
out continually from the cooling water
pilot outlet.
5. Run the engine at idling speed for about
3 minutes watching the engine condition.
If the engine stops while flushing, turn
the water supply off immediately and
repeat the above steps.
6. Turn the water supply off, and then force
the remaining water out from the cooling
passages by alternately squeezing, and
releasing the throttle lever for 10 to
15 seconds.

Lubrication
1. Remove the spark plugs and pour
approximately one tablespoon of oil into
each cylinder.
2. Grease the spark plug threads and rein-
stall the spark plugs.
3. Crank the engine within 3 seconds using
the start switch.
4. Lubricate all cables such as the throttle,
choke, and steering cables.
NOTE:@ Use a suitable marine grease applicator to
pressure lubricate the cables and purge out
any moisture between the inner and outer
cables.
@
5. Lubricate the areas of the watercraft
specified under Lubrication points on
page 4-16.

Fuel system
Draining the fuel system prevents buildup
of varnishes and other harmful deposits that
result when gasoline sits for a prolonged
period of time.
WARNING@ GASOLINE AND ITS VAPORS ARE
HIGHLY FLAMMABLE AND EXPLOSIVE!

Do not smoke when refueling, and
keep away from sparks, flames, or
other sources of ignition.

Stop engine before refueling.

Refuel in a well-ventilated area with
the watercraft in a horizontal position.

Do not stand or sit on the watercraft
while refueling in case of fire.

Take care not to spill gasoline. If gaso-
line spills, wipe it up immediately with
dry rags. Always properly dispose of
gasoline-soaked rags.

Adjusting the carburetor
The carburetor is a vital part of the engine
and requires very sophisticated adjustment.
Most adjusting should be left to a Yamaha
dealer who has the professional knowledge
and experience to perform it. However, the
operator may adjust the trolling speed as
part of the usual maintenance routine.
CAUTION:@ The carburetor was set at the Yamaha
factory after many tests. If the settings
are disturbed by someone who does not
have the necessary technical knowledge,
poor engine performance and damage
may result.
@
EJU01110
Adjusting the trolling speed
1. Put the watercraft in the water.
2. Start the engine and warm it up for 1 or
2 minutes. Using a diagnostic tachome-
ter or, if necessary, the tachometer in the
multifunction information center, adjust
the engine speed to specification.
3. Turn the throttle stop screw 1 clockwise
to increase engine speed if necessary.
Turn it counterclockwise to decrease
engine speed if necessary.
Trolling speed: 1,300–1,400 r/min
