BASIC MAINTENANCE

6.1 GENERAL
Regularly check that power cable connections are tightened correctly and are in good condition.
If the vessel is to remain out of the water for some time, for example dry storage for winter,
the underwater mechanism must be thoroughly rinsed with fresh water, then the thruster
column must be liberally greased. Inspect and repair the hull closing plate gasket for
deterioration or missing pieces. Check and tighten, if necessary, the hull fixing bracket
screws. NEVER use acids, chlorine solutions (even at low concentrations) or solvents
during cleaning, these products can damage the straps, gaskets or gussets irreparably,
and thus impair the integrity of the device. A correctly installed retractable thruster should
not show any sign of underwater concretions since it is most of the time in the closed
position and therefore not exposed to light. It is therefore not necessary and even
prohibited to coat the Compact Retract, even partially, with paint or antifouling, as the
chemical agents in their composition can harm the integrity of the device. It is also
prohibited to use any contant or sharp object that could damage certain vital organs of the
device (straps and bellows in particular) to clean the unit.
6.2 CONTROL PANEL
Control panel(s) should be protected from the natural elements while the thruster is not in use.
The area behind the dashboard should be kept dry at all times to avoid the risk of
oxidation of the cable connector contacts.
6.3 RELAY BOX & ELECTRONIC CONTROL BOX
Relay box and electronic control box must be kept in dry and ventilated area and fitted
above the waterline.
6.4 BATTERIES
Check regularly the condition of the batteries used for the thruster and its charging system.
Weak batteries (low voltage) are the most frequent cause of rapid deterioration of the
thruster relay and motor.
6.5 COMPOSITE DRIVE LEG
The composite drive leg is lubricated for life.
The composite drive leg does not require an anode.
When the boat is ashore, check for evidence of fishing line, etc... in the propellers.
For prevention of calcium build up on the drive shafts, which would damage the oil seals,
before fitting the propeller(s), cover drive shaft and the oil seals stainless steel cover with
silicon grease. This should be done on an annual basis after cleaning of outside of leg.
Do not use aggressive solvents as they might damage drive leg
seals. Always keep the propellers and tunnel clean.
