Drive Housing Lubricant
DRAINING LUBRICANT
NOTE: When draining the drive housing lubricant, visually check
for water in the lubricant. It may have settled to the bottom and will
drain before the lubricant or it may have mixed with the lubricant,
giving it a milky color. In either case, have the drive housing
checked by your authorized Mercury Marine dealer. Water in the
lubricant can cause premature gear or bearing failure or, in
freezing weather, damage to the drive housing.
