Spark plug
IMPORTANT: Please follow the instructions below:
• Do not touch the high tension cables running from the ignition
coil to the spark plugs while the engine is running or it is turned
by the electric starter motor, not even for testing the high
tension cables or the spark plugs.
• The high tension cables and the spark plugs generate very
high electric voltage, which can cause a serious electric shock
if touched.

Lubrication Points

It is important to inspect and maintain your outboard motor
regularly. Maintenance intervals should be determined according
to the number of hours or number of months, whichever comes
first. For periodic servicing and maintenance guidelines, please
contact your local Mercury dealer.

Gearcase Lubrication

When adding or changing gearcase lubricant, visually check for
the presence of water in the lubricant. If water is present, it may
have settled to the bottom and will drain out prior to the lubricant,
or it may be mixed with the lubricant, giving it a milky colored
appearance. If water is noticed, have the gearcase checked by
your dealer. Water in the lubricant may result in premature bearing
failure or, in freezing temperatures, will turn to ice and damage the
gearcase.
