Sacrificial anodes. Checking
1. Check the sacrificial anodes located on the upper
housing, trim cylinder and at the base of the
propeller shaft.
2. Replace with new anodes when approximately
30% of the anode has been eroded. Note that
most stainless steel propellers (accessories) use
the sacrificial anodes faster than normal.
IMPORTANT! Tighten the new anodes so that
there is a good metallic contact is retained.
IMPORTANT! Use zinc sacrificial anodes for salt
water and magnesium anodes for freshwater.
The sacrificial anodes oxidize in contact with air, which
diminishes the galvanized protection. Even a new an-
ode can be oxidized on the surface. Therefore always
clean the sacrificial anodes before launching the
boat.
IMPORTANT! Use emery paper. Do not use a wire
brush or other steel tools when cleaning, as these
may damage the galvanic protection.
Replacing sacrificial anodes
1. Remove the screw holding the anodes onto the
gearcase. Set the screws aside, as you will use
them again.
2. Pull off the old anode.
3. Insert the new anode.
4. Secure with screw.
5. Tighten screw to 6,8 – 9,5 Nm (60 – 84 in. lb.) for
the gearcase anode
If additional electronic or electrical equipment is
installed, each item should have an individual anode or
grounding device and all grounding devices must be
interconnected. Follow equipment manufacturer’s
recommendations.
