Gearcase Lubrication - Mercury 200 OptiMax DTS Manual

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.
Examine the drained gearcase lubricant for metal particles. A
small amount of 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.
