INSPECTION AND MAINTENANCE
2. Spark gap (0.8–0.9 mm, 0.031–0.035 in)
ENON00028-0
Note
 Spark plug torque:
18.0 Nm (13.3 ft-lb) [1.84 kgf-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.

Replacing the anode
A sacrificial anode protects the outboard
motor from galvanic corrosion. Anode is
located on the gear case and the cylinder.
When the anode is eroded more than 2/3,
replace it.
ENON00029-0
Notes
 Never grease or paint the anode.
 At each inspection re-tighten the anode
attaching bolt. As it is likely to be sub-
jected to electrolytic corrosion.
