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, turn the
key switch OFF and disconnect battery neg-
ative  (–)   cable  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.
To remove spark plugs, twist and remove all spark
plug leads. Unscrew spark plug from cylinder head.
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.
Installation
Slide thrust washer onto shaft with shoulder facing
aft.
Slide propeller onto shaft, engaging the splines and
seating it on the thrust washer.
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 to a torque of 120 in.
