SPARK PLUG CLEANING AND
ADJUSTMENT
The spark plug is an important engine
component and is easy to inspect. The
condition of the spark plug can indicate
something about the condition of the
engine. For example, if the center elec-
trode porcelain is very white, this could
indicate an intake air leak or carbure-
tion problem in that cylinder.
Do not attempt to diagnose any prob-
lems yourself. Instead, take the Sport
Boat to a Yamaha Sport Boat dealer.
You should periodically remove and
inspect the spark plug because heat
and deposits will cause the spark plug
to slowly break down and erode. If
electrode erosion becomes excessive,
or if carbon and other deposits are
excessive, you should replace the
spark plug with another of the correct
type.
Standard spark plug:
CR9EB
Before installing the spark plug, mea-
sure the electrode gap with a wire
thickness gauge; adjust the gap to
specification if necessary.
Spark plug gap: 0.7~0.8mm
(0.028~0.031 in)

When fitting the plug, always clean the
gasket surface and use a new gasket.
Wipe off any dirt from the threads and
screw in the spark plug to the correct
torque.
Spark plug torque:
13 Nm (1.3 m-kg, 9.4 ft-lb)
NOTE: Before installing the spark plug
cap, be sure to wipe off any water on
the spark plug or inside the cap. Push
the spark plug cap down until it clicks.
NOTE: If a torque-wrench is not avail-
able when you are fitting a spark plug,
a good estimate of the correct torque
(with a new gasket) is 1/4 to 1/2 turn
past finger-tight. Have the spark plug
adjusted to the correct torque as soon
as possible with a torque wrench.
WARNING
When removing or installing a spark
plug, be careful not to damage the
insulator. A damaged insulator could
allow external sparks, which could
lead to explosion or fire.
