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.

1. Place a drain pan below the drive.
