Incorrect spark plugs can cause
engine damage.
RECOMMENDED SPARK PLUGS:
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.’’
Do not adjust the spark plug gap.
If the gap is out of specification,
replace the spark plug with a new
one.
Disconnect the battery negative
(
) terminal.
Unlock and remove the engine
cover (p.
).
