Engine anode
In order to protect the engine and
its raw water system from corro-
sion, the engine is fitted with a zinc
anode.
Intervals given in the service sched-
ule are recommendations. Depend-
ing upon operating conditions and
raw water properties, it might be
necessary to check and/or change
the anode more frequently.
To remove the anode:
I WARNING
Carry out these operations when
the engine is stopped and cold.
1. Remove the key from the panel.
2. Close the sea cock.
3. Drain the raw water system.
4. Remove the set formed by a
cap, a seal and the anode.
5. Remove the deposits from the
surface of the anode using glass
paper before determining the
level of erosion. Do not use a soft
steel brush as this could leave
deposits that are likely to speed
up corrosion.
6. If more than 50% of the anode
has been used up, change it
along with the seal.
The length of a new anode is 16
mm.
I CAUTION
Screw the anode cap back on
tightly and do not forget to re-
open the sea cock.
