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. Check for water at bottom of monitor and/or if oil appears a
milky tan, contact your Authorized MerCruiser Dealer immedi-
ately; both conditions 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 lubrica-
tion. Contact your Authorized MerCruiser Dealer for service.

from filler neck.

restricted.
