BTR propeller from power.

Maintenance

Quick 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 inefficiency.
ACCORDING TO THE USE WE RECOMMEND CHECKING PERIODICALLY THE OIL SEALS AND IF NECESSARY
REPLACING THEM.
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, tunnel and gearleg.
• Replace the anodes (carry out this operation more often if needed) and,
if possible, grease the double joint with marine grease (fig. 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 anodes,
the sealings and the gearlegs' shafts where the propellers are lodged.
