MAINTENANCE
These spark plugs have an iridium
coated center electrode. Be sure to
observe the following when servicing
iridium 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.
The cleaning of the iridium spark
plugs consult with an authorized
TOHATSU outboard motor dealer,
unless the owner has the proper
tools and is mechanically
proficient.
• 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.''
The gaps should be 1.0 – 1.3 mm
(0.039 – 0.051 in).
• Do not adjust the spark plug gap.
If the gap is out of specification,
replace the spark plug with a new
one.
