Note
z 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
The anode protects the outboard motor
from galvanic corrosion (metal corrosion
caused by feeble electricity).
Anodes are installed under the anti-ventila-
tion of the gear case, the left cramp
bracket (port side) and the left mount
bracket (port side).
When an anode is worn down under 2/3 of
its original size (of new port), replace it.

Notes
z 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.
