Checking
NOTE: Oil level will fluctuate during operation. Oil level should be checked with the engine
cold, before starting.
1. Check the gear lube oil level. Keep the oil level at or near FULL line in the drive lube
monitor. If any water is visible at the bottom of the monitor or appears at the oil fill/drain
plug and/or if oil appears discolored, contact your authorized Mercury MerCruiser dealer
immediately. Both conditions may indicate a water leak somewhere in the sterndrive
unit.
