Gear Case Lubrication
When adding or changing gear case 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 gear case 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 gear case.
Whenever you remove the fill/drain plug, examine the magnetic end
for metal particles. A small amount of metal filings or fine metal par-
ticles indicates normal gear wear. An excessive amount of metal fil-
ings or larger particles (chips) may indicate abnormal gear wear and
should be checked by an authorized dealer.
DRAINING GEAR CASE
1 Place outboard in a vertical operating position.
2 Place drain pan below outboard.
3 Remove vent plug.
4 Remove fill/drain plug and drain lubricant.
