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 particles indicates normal gear wear. An ex-
cessive amount of metal filings or larger particles (chips) may indicate abnormal gear
wear and should be checked by an authorized dealer.
DRAINING GEAR CASE
NOTE: Some models may have the vent and fill/drain plugs on the opposite side.
1. Place outboard in a vertical operating position.
2. Place drain pan below outboard.
3. Remove vent plug and fill/drain plug and drain lubricant.
