SPARK PLUGS
PROPELLER
WARNING
WARNING
The ignition system presents a serious
shock hazard. The primary circuit operates
in excess of 250 volts; the secondary circuit
operates in excess of 25,000 volts. Use cau-
tion to avoid injury from shock or injury
resulting from your reaction to shock. Do
not handle primary or secondary ignition
components while the engine is cranking or
running.
When servicing the propeller, always shift
the outboard to NEUTRAL position, and
twist and remove all spark plug leads so the
engine cannot be started accidentally.
IMPORTANT: Apply Triple-Guard grease to the en-
tire propeller shaft before installing the propeller. At
least annually, remove the propeller and check for
debris. Clean the shaft and regrease it before rein-
stalling a propeller.
Inspect spark plugs periodically. Replace if elec-
trodes are badly worn, insulators are cracked, or if
they are badly fouled.
Installation
Slide thrust washer onto shaft with fish line trap
groove facing forward.
To remove spark plugs, twist and remove all spark
plug leads. Unscrew spark plug from cylinder head.
Slide propeller onto shaft, engaging the splines and
seating it on the thrust washer.
To install spark plugs, wipe spark plug seats clean
with a clean rag. Install spark plugs finger tight, then
tighten to specified torque. Refer to Engine Speci-
fications.
Slide spacer onto the shaft and engage the propel-
ler shaft splines.
Wedge a block of wood between the propeller
blade and the antiventilation plate.
IMPORTANT: Avoid engine damage by installing
spark plugs into COOL cylinder head and not over-
tightening.
Before installing the spark plug lead, apply a light
coat of Triple-Guard grease to the ribbed portion of
the spark plug. This will help prevent corrosion be-
tween the spring terminal and the spark plug.
Install propeller nut and tighten securely.
