SPARK PLUGS

WARNING
The ignition system presents a serious
shock hazard. Use caution 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 crank-
ing or running.
Spark plugs should be serviced by an
Evinrude E-TEC Dealer. Incorrect spark plug
maintenance can lead to engine damage.
IMPORTANT: Replacement spark plugs
MUST be indexed correctly.
Marine Engine Duty Cycles
The International Council of Marine Industry
Associations (ICOMIA) Standard No. 36-88
specifies a marine engine duty cycle based on
documented studies. A duty cycle is a profile
of engine running and usage. This duty cycle
is used to determine average spark plug lon-
gevity and maintenance requirements for
Evinrude E-TEC outboards.

IMPORTANT: Some running profiles and
conditions can lead to spark plug wear sooner
than expected. Depending on your specific
usage, the spark plug maintenance schedule
may require adjustment.

FUSE

On outboards equipped with an accesso-
ry electric starter, a blown fuse will not allow
the engine to start. Replace it with a fuse of
the same rating. A spare fuse is provided.
Repeated fuse failures indicate a potentially
serious problem. Do not replace it with higher
rated fuse; see your Dealer for service.
In an emergency, the engine may be rope-
started and run, this will not harm the engine.
Fuse Replacement
IMPORTANT: Use only fuses of the same rat-
ing. Your Evinrude E-TEC outboard uses 10-
amp fuses.
Remove engine cover. Install spare fuse in
place of failed fuse.
