Notes
When inspecting 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.
Stop the engine.
Remove the top cowl.
Remove the spark plug caps.
Remove the spark plugs by turning
it counter-clockwise, using a 5/8"
socket wrench and handle.
Attach spark plug and tighten to
specified torque.
Use spark plug NGK DCPR-6E.
Electrode
Spark gap
(0.8 to 0.9 mm, 0.031 to 0.035 in)
Notes
Spark plug torque :
18.0Nm(13.3ft-lb)(1.8kgf-m)
If a torque-wrench is not available
when you are fitting a spark plug, a
good estimate of the correct torque
is 1/4 to 1/2 a turn past finger-tight.
Have the spark plug adjusted to the
correct torque as soon as possible
with a torque-wrench.
INSPECTION AND MAINTENANCE
Replacing the anode
A sacrificial anode protects the
o u t b o a r d m o t o r f r o m g a l v a n i c
corrosion. Anode is located on the
gear case. When the anode is eroded
more than 2/3, replace it.
Notes
Never grease or paint the anode.
At each inspection re-tighten the
anode attaching bolt. As it is likely
to be subjected to electrolytic
corrosion.
