The stator is protected by an anode housed under a plastic plug located on the
starboard side the stator. To remove the anode, first open the arrester screw
and unscrew the plug. Now you can replace the anode located inside the plug.
Leave the screw that holds the anode in place (figure 10, point A) loose and
fasten the plug into place using a sealing compound (such as Sikaflex 221).
Only then attach the other end of the arrester to the stator. After this, tighten
the screw that holds the anode in place.
Replacing the anodes located inside the frame
Figure 11. Replacing the anodes on the frame
There are two anodes installed under the domes located on either side of
the frame (figure 11, point A). To replace these anodes, open the inspection
hatch and unscrew the nuts holding the anodes attached to the frame (figure
11, point B). Place the new anode so that the screw attached to the frame
goes through the hole in the centre of the anode. Lock the anode in place by
tightening the nut over the centre screw. During installation, make sure that
the curved surface of the anode is placed against the dome located on the
frame and that the screw stays in place.
4.2.2. Touch-up painting and antifouling
The aluminium castings have been protected with paint. Painting efficiently
prevents the propagation of various forms of corrosion, e.g. pit corrosion.
Bare aluminium, on the other hand, is liable to corrosion in difficult conditions.
This is why it is important to carry out touch-up painting if paint comes loose
and aluminium is exposed. Touch-up painting can be done in various ways.
What is important is that the paints used are suitable for aluminium and that
the paint manufacturer's instructions are followed during painting. The jet's
colour is RAL 7035.
If the boat is going to be used in waterways where the growth and sticking
of organisms around the boat’s bottom and the propulsion unit is heavy,
