Checking the spark plugs

WARNING

EWJ00351

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.

Remove and check the condition of the spark
plugs.
The condition of a spark plug can indicate
something about the condition of the engine.
For example, if the center electrode portion is
very white, this could indicate an intake air
leak or carburetion problem in that cylinder.
Do not attempt to diagnose any problems
yourself. Have a Yamaha dealer service the
watercraft.
To remove a spark plug:
(1) Remove the hood. (See page 24 for hood

removal and installation procedures.)

(2) Remove the spark plug cap.
(3) Remove the spark plug, and then check

the condition of the spark plug and the
spark plug gap. If the electrode portion is
significantly discolored, if electrode ero-
sion becomes excessive, if carbon and
other deposits are excessive, or if the
spark plug gap is not within the specified
range, replace the spark plug.

TIP:

When the engine is operating normally, the
color of the spark plug electrode portion will
be a medium-to-light tan.

To install a spark plug:
(1) Wipe off any dirt from the threads, insu-

lator, and gasket surface of the spark
plug.

(2) 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.
