Gear Lube Oil
NOTICE
Discharge of oil, coolant, or other engine/drive fluids into the environment is restricted by
law. Use caution not to spill oil, coolant, or other fluids into the environment when using
or servicing your boat. Be aware of the local restrictions governing the disposal or
recycling of waste, and contain and dispose of fluids as required.
Checking
NOTE: The level of gear lube oil will fluctuate during operation. Check the oil level with the
engine cold, before starting.
1. Check the gear lube oil level. Keep the oil level within the recommended operating
range. If any water is visible at the bottom of the monitor or appears at the oil fill/drain
plug or if oil appears discolored, contact your authorized Mercury MerCruiser dealer
immediately. Both conditions may indicate a water leak somewhere in the sterndrive
unit.

Filling
IMPORTANT: A leaking seal may cause a lack of sufficient lubrication, which can cause
damage to the sterndrive unit. Using more than 59 ml (2 fl. oz.) of High Performance Gear
Lubricant to fill the monitor may indicate a leaking seal. Contact your authorized Mercury
MerCruiser dealer.
1. Remove the gear lube monitor cap.
2. Fill the monitor with the specified fluid so that the oil level is in the operating range. Do
not overfill.
