15.3 BOW THRUSTER (RETRACTABLE)
General points
- The bow-thruster's motor is DC powered.
- The bow-thruster assists with steering the boat when manoeuvering at low speed (picking
up a mooring buoy or berthing on a pontoon for instance).
- An operating relay is installed in the circuit.
- A fuse protects the electrical circuit.
- The bow-thruster motor has its own battery bank.
Operation
- Turn on the bow thruster battery switches.
- The engine's positive battery isolator automatically comes on and goes off when the engine
is started/stopped. The thruster circuit negative is connected to the boat's general negative.
- The bow-thruster motor must operate with the boat's engine running.
- A control panel is located in the cockpit.
- To switch the bow-thruster motor on or off, press and hold in the red and green button
simultaneously for several seconds.
- When the bow-thruster motor is not in use, switch off the electrical supply both:
- to the control panel,
- and to the switches of the motor's batteries.
Maintenance
- The bow-thruster's motor:
- is lubricated for life and the oil does not require draining;
- must not be dismantled, even partially.
- Regularly check the charge state of the motor's batteries: a loss of voltage will cause
premature wearing of the motor's relay contacts and brushes.
During lift-out
- Check that the propellers turn properly, with neither play nor stiffness.
- Clean the blades carefully.
- Remove the propeller, clean the shaft support, smear the shaft with silicone-based grease
before refitting the propeller.
- After cleaning and applying a primer, antifoul the housing and the propellers.
