EJU34381Cleaning and adjusting the spark
plugs
The spark plug is an important engine compo-
nent and is easy to inspect. The condition of
the spark plug can indicate something about
the condition of the engine. For example, if
one spark plug has a distinctly different color,
the engine could require servicing. Do not at-
tempt to diagnose any problems yourself.
Have a Yamaha dealer service the watercraft.
Remove and inspect the spark plugs periodi-
cally; heat and deposits will cause the spark
plugs to slowly break down and erode. If elec-
trode erosion becomes excessive, or if carbon
and other deposits are excessive, replace the
spark plug with the specified plug.
To remove a spark plug:
(1) Remove the air filter case cover and air
filter element. (See page 84 for air filter
element removal and installation proce-
dures.)
(2) Remove the spark plug cap.
CAUTION:
ECJ00210
Do not use any tools to remove or install
the spark plug cap, otherwise the ignition
coil coupler could be damaged. The spark
plug cap may be difficult to remove be-
cause the rubber seal on the end of the
cap fits tightly. To remove the spark plug
cap, simply twist it back and forth while
pulling it up; to install it, twist it back and
forth while pushing it down.
(3) Remove the spark plug.
Measure the spark plug gap with a wire
thickness gauge. Replace the spark plugor adjust the gap to specification if neces-
sary.
To install a spark plug:
(1) Clean the gasket surface.
(2) Wipe any dirt from the threads of the
spark plug.
(3) Install the spark plug, and then tighten it
to the specified torque.
(4) Install the spark plug cap.
NOTE:

Wipe off any water on the spark plug or in-
side the spark plug cap before installing the
cap. Push the spark plug cap down until it is
securely installed.

If a torque wrench is not available when you
are installing a spark plug, a good estimate
of the correct torque is 1/4 turn to 1/2 turn
past finger tight using the spark plug
wrench included in the tool kit. Have the
spark plug adjusted to the correct torque
with a torque wrench as soon as possible.
Specified spark plug:

CAUTION:
ECJ00660

Place a suitable clean cloth or carpeting
underneath the watercraft to protect it
from abrasions and scratches.

Always turn the watercraft over onto its
port (left) side.

When turning the watercraft on its side,
support the bow so that the handlebars
are not bent or damaged.
(2) Remove any weeds or debris from
around the drive shaft, impeller, jet pump
housing, and jet thrust nozzle.
If debris is difficult to remove, consult a
Yamaha dealer.
CAUTION:
ECJ00670
Always avoid operating your watercraft in
areas where weed growth is thick. If travel-
ing in weeded areas is unavoidable, oper-
ate the engine alternately at partial throttle
and full throttle. Weeds tend to accumu-
late more at a steady speed and at trolling
speed. If weeds clog the jet intake or im-
peller area and cause cavitation, follow the
cleaning procedure above.
EJU34640Jumping the battery
If the watercraft battery has run down, the en-
gine can be started using a 12-volt booster
battery and jumper cables.
WARNING
EWJ00790
Battery electrolyte is poisonous and dan-
gerous, causing severe burns, etc. Elec-
trolyte contains sulfuric acid. Avoid
contact with skin, eyes, or clothing.
Antidotes
External: Flush with water.
Internal: Drink large quantities of water or
milk. Follow with milk of magnesia, beatenegg, or vegetable oil. Call a physician im-
mediately.
Eyes: Flush with water for 15 minutes and
get prompt medical attention.
Batteries produce explosive gases. Keep
sparks, flames, cigarettes, etc., well away.
If using or charging the battery in an en-
closed space, make sure that it is well ven-
tilated. Always shield your eyes when
working near batteries.
KEEP OUT OF THE REACH OF CHILDREN.
EJU34660Connecting the jumper cables
(1) Connect the positive (+) jumper cable to
the positive (+) battery terminals of both
batteries.
(2) Connect one end of the negative (–)
jumper cable to the negative (–) battery
terminal of the booster battery.
(3) Connect the other end of the negative (–)
jumper cable to an engine hanger.
CAUTION:
ECJ00680
Do not connect the end of the negative (–)
jumper cable to the negative (–) battery
terminal of the watercraft battery! Make
sure that all connections are secure and
correct before attempting to start the en-
1Positive (+) jumper cable
