®
Thrusters are made in materials that are resistant to the sea environment: In any case, it is indispensable to periodi-
cally remove salt deposits that form on the outer surfaces to avoid corrosions and consequent system inefciency.
WARNING: make sure that the power supply to the electric motor is not switched on when maintenance operations
are carried out.

Dismantle once a year, following the points below:
• Clean propellers (78 and 79), tunnel (83) and gearleg (76).
• Replace the anodes (carry out this operation more often if needed) and,
if possible, grease the double joint (49) with marine grease (g. 25).
• Replace the propellers if damaged or worn out.
• Check the tightness of all screws.
• Ensure that there is no water seepage inside.
• Check that all electrical connections are well tightened and oxide-less.
• Check that the batteries are in good conditions.
WARNING: do not paint the zinc anodes (57 and 81),
the sealings and the gearlegs’ shafts where the propellers are lodged.
