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.
