Spark Plugs
Use only the recommended type of spark
plugs in the recommended heat range. It
should not be necessary to use spark plugs in
a different heat range because the engine is
water-cooled.
Using spark plugs with an improper heat
range can cause engine damage.
This PWC 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.
To prevent damaging the iridium coating of
the center electrode, never use a
“ leaf-type
feeler gauge. ”
