3. Remove the spark plug caps.
4. Remove the spark plugs by turning it
counter-clockwise, using a 5/8" socket

Note
Spark plug torque:
18.0Nm(13.3ft-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.

Checking and Refilling Oil in the
Power Tilt.

the tank.
Remove the oil cap by turning counter-
clockwise, then check if the oil level
reaches the bottom line of the plug
hole.
