To remove a spark plug:
(1) Remove the seats. (See page 30 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.
NOTE:
If removing the spark plug cap nearest the
stern, remove the plastic tie that is securing
the wiring harness before removing the 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.
(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.
NOTE:
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-
