EJU37041Cleaning and adjusting the spark
plugs
WARNING
EWJ00350
Be careful not to damage the insulator
when removing or installing a spark plug.
A damaged insulator could allow sparks to
escape, which could result in a fire or ex-
plosion.
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 seats. (See page 25 for seat
removal and installation procedures.)
(2) Remove the engine cover screws, and
then remove the engine cover.
(3) Remove the spark plug cap bolts, and
then remove the spark plug cap.
NOTICE: Do not use any tools to re-
move 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.

TIP:
If removing the spark plug cap nearest the
stern, remove the plastic tie that is securing
the wiring harness before removing the cap.
(4) Remove the spark plug.
Measure the spark plug gap with a wire
thickness gauge. Replace the spark plug
or 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.
TIP:
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 in-
cluded in the tool kit. Have the spark plug ad-
justed to the correct torque with a torque
wrench as soon as possible.
(4) Wipe off any water on the spark plug or
inside the spark plug cap, and then install
the cap. Push the spark plug cap down
until it is securely installed, and then in-
stall the spark plug cap bolts and tighten
them to the specified torque.
If the spark plug cap nearest the stern
was removed, secure the wiring harness
by installing the plastic tie after installing
the cap.
(5) Install the engine cover and engine cover
screws, and then install the seats.

EJU34452Checking the battery
Check the level of the battery electrolyte and
make sure that the negative (–) and positive
(+) battery leads are tightened securely.
WARNING
EWJ00791
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, beaten
egg, 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.
To remove the battery:
Disconnect the negative (–) battery lead first,
then the positive (+) battery lead and breather
hose, and then remove the battery from the
watercraft.
To replenish the battery:
(1) Make sure that the electrolyte level is be-
tween the maximum and minimum level
marks.
(2) If the electrolyte level is low, add distilled
water to raise it to the specified level.
NOTICE: Use only distilled water for
replenishing the battery, otherwise
battery life could be shortened.
[ECJ00241]
To recharge the battery:
NOTICE
ECJ00250
Do not attempt to charge a battery hastily.
Battery life could be shortened.
It is recommended to have a Yamaha dealer
charge the battery. If you charge the battery
yourself, be sure to read and follow the in-
structions provided with the battery tester and
charger you use. Grease quantity:
Initial 10 hours or 1 month:
33.0–35.0 cm³ (1.12–1.18 US oz,
1.16–1.23 Imp.oz)
Every 100 hours or 12 months:

To install the battery:
(1) Place the battery in the battery compart-
ment. Connect the red lead to the positive
(+) battery terminal, and then connect the
black lead to the negative (–) battery ter-
minal. NOTICE: Reversal of the battery
leads will damage the electrical parts.
[ECJ00261]

(3) Secure the battery in place. WARNING!
Fire or explosion could result if the
breather hose is damaged, obstruct-
ed, or not connected properly.
