Spark Plug Service

RECOMMENDED SPARK PLUG:
IZFR6K-11E (NGK)
Incorrect spark plugs can cause
engine damage.
This outboard motor uses spark plugs
that have an iridium coated center
electrode. Be sure to observe the
following when servicing the spark
plugs.
• Do not clean the spark plugs. If an
electrode is contaminated with
accumulated objects or dirt, 
replace the spark plug with a new
one.
• Use only a ''wire-type feeler
gauge'' to check the spark plug gap
if necessary. To prevent damaging
the iridium coating of the center
electrode, never use a ''leaf-type
feeler gauge.''
