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.
