refer to Filling.

3. Inspect the gear lube condition. If any water is visible in the bottom of the gear lube monitor, if water appears at the fill and
drain plug hole, or if the gear lube appears discolored, these conditions can indicate a water leak in the sterndrive. Contact
your authorized Mercury MerCruiser dealer.
Filling
IMPORTANT: If more than 59 ml (2 fl. oz.) of gear lubricant is required to fill the monitor, a seal may be leaking. Damage to the
sterndrive unit may occur due to lack of lubrication. Contact your authorized Mercury MerCruiser dealer.
1. Remove the gear lube monitor cap.
