26 ZT370 Operation Manual
Check the Stern-Drive Oil Level
*1: Quick Silver is a registered trademark of
Brunswick Corporation.
Note: The oil level will rise and fall during
operation. Check the oil level before
starting, when the engine is cold.
1. Check the stern-drive oil level
(Figure 2). Keep the oil level at or near
the OPERATING RANGE (full) line
(3, Figure 2) on the oil reservoir
(1, Figure 2).
2. The oil level is low if it is below the ADD
line (2, Figure 2) on the oil reservoir
(1, Figure 2). Fill as needed with the
specified oil. See Fill the stern-drive
with oil on page 26.
Figure 2
If any water is visible at the bottom of the
oil reservoir or appears at the oil fill/drain
plug and/or if oil appears discolored,
consult your authorized Yanmar Marine
dealer or distributor immediately. Both
conditions may indicate a water leak
somewhere in the stern-drive.
■ Fill the stern-drive with oil
See Changing the stern-drive oil on
page 36 when filling the entire stern-drive.
If more than 60 ml (2 fl oz) of gear oil is
required to fill the reservoir, a seal may be
leaking. Damage to the stern-drive may
occur because of lack of lubrication.
Consult your authorized Yanmar Marine
dealer or distributor.
1. Remove the oil reservoir cap
(1, Figure 3).
2. Fill the oil reservoir to the OPERATING
RANGE (2, Figure 3) (full) line with
specified fluid.
Do not overfill.
