Lubrication Points
It is important to inspect and maintain your outboard motor regularly.

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.
Remove the fill/drain plug and examine the magnetic end for metal particles. A
small amount of metal filings or fine metal particles indicates normal gear wear.
An excessive amount of metal filings or larger particles (chips) may indicate
abnormal gear wear and should be checked by an authorized dealer.
CHANGING GEAR OIL
1. Place the outboard in a vertical operating position.
2. Place a drain pan below the outboard.
