Checking Fluid Level

NOTE: Fluid level in gear lube monitor will fluctuate during operation. Level should be
checked with engine cold.
1. Check for water at bottom of monitor, or milky-tan appearance. Both conditions indicate
a water leak somewhere in the sterndrive unit. Find and correct the cause.
2. Check gear lube monitor oil level. Keep oil level at or near "OPERATING RANGE
(FULL)" line and never below the "ADD" line.

Filling

1. Remove cap.
2. Add High Performance Gear Lube to gear lube monitor as needed.
IMPORTANT: If more than 57 grams (2 oz.) of High Performance Gear Lube are
required to fill drive unit, a seal may be leaking. Damage to the unit may occur due
to a lack of lubrication.
