Alternative B, draining through the drain plug
1 Open the
oil filler cap (1) so that excess pressure
is released. Open the drain plug (5) and let the
oil run out.
2 Change the filter (4).
3 Reinstall the drain plug with a new O-ring.
Always fit a new O-ring when the drain plug has
been removed.
4 Measure out the correct volume of oil and fill the
drive via the oil filler hole; refer to Sterndrive for
oil grade and volume.
5 Calibrate the water-in-oil sensor; refer to
Service page 121.
Corrosion protection, checking and
changing
Check the sacrificial anodes regularly. There are two
anodes per
stern drive; one is fixed to the drive and the
other to the transom. Refer to the illustrations. Replace
an anode when approximately 1/3 of it has corroded
away.
When the boat is stored ashore, corrosion protection
deteriorates due to sacrificial anode oxidization. Even
new anodes oxidize on the surface. The anodes must
be cleaned before the boat is launched.
The anode in the exhaust outlet is made of iron and
does not need cleaning.
IMPORTANT!
Use emery paper. Do not use a wire brush or other
steel tools when cleaning, as these may damage the
galvanic protection.
Replacing corrosion protection
All anodes are secured by bolts or nuts. Remove the
anode retaining bolts or nuts. Clean the contact sur-
face and secure the new anode. Tighten the new
anode so that it makes good electrical contact.
