CHECKING DRIVE UNIT OIL
NOTE: Oil level will fluctuate during operation. Oil level should be
checked with cold engine before starting.
1 Check gear lube monitor oil level. Keep oil level at or near FULL
line. If any water is visible at the bottom of monitor or appears at the
oil fill/drain plug and/or if oil appears discolored, contact your
Authorized MerCruiser Dealer immediately. Both conditions may
indicate a water leak somewhere in the drive unit.
IMPORTANT: If more than 2 fl. oz. (59ml) of Quicksilver High
Performance Gear Lube is required to fill monitor, a seal may be
leaking. Damage to drive unit may occur due to lack of
lubrication. Contact your Authorized MerCruiser Dealer for
service.
