Thrusters are made in materials that are resistant to the sea
environment: In any case, it is indispensable to periodically remove
salt deposits that form on the outer surfaces to avoid corrosions
and consequent system inefficiency.
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 (13 and 14), tunnel and gearleg (10 or 11).
• Replace the zinc anodes (carry out this operation more often if
needed).
• 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 anodes (16), the sealing and the
gearleg’s shafts where the propellers is lodged.
