9.3 BOW AND STERN THRUSTERS

The thruster is a very simple and robust accessory, but it requires some attention:

The thruster must be used at a very low speed, or without fresh way; at higher speed, more correct reactions can be obtained with the offset use of the gear boxes;
Each time the yacht is lifted up, check the condition of each thruster, of the protection anodes and of the fastening system.

MAINTENANCE

At least once a week check the correct operation.
At least once every three months check the status of the sacrificial anodes and if necessary, replace them.
When necessary top up oil.

NOTE

For further information on use and maintenance, please refer to the manufacturer’s manual.

Use of the thruster
Enable the relevant controls via the monitoring system and press the ON button on the joystick of the chosen control panel (bridge, fly bridge or third station). A continuously on indicator light confirms readiness for use. The propellers are controlled via the control joysticks.

WARNING

When the thruster is no longer in use, press the OFF button on the control panel.

CAUTION

In case it is necessary to replace a fuse on the thruster system, have this operation carried out by a skilled naval electrician. Take care to carry out a preliminary inspection of the relevant thruster technical operation documents or to contact the Service Department.

WARNING

The synoptic panel of the main helm station carries a light which, if alight, indicates that the bow thruster is supplied.

CAUTION

For the continuous operation of the thruster, refer to the manual delivered by the Manufacturer.

DANGER

During the thruster operation, pay attention to possible swimmers or small boats which may be close to the thruster openings.
Do not test the thruster when the yacht is outside water, unless you are sure the workers are at safety distance from the thruster tunnel.

CAUTION

When the bow thruster is not used, always disconnect the control unit.

DANGER

Always stop the thruster before undertaking inspection or maintenance tasks by disconnecting the switches and possibly also the battery terminals.

CAUTION

Never activate the thruster longer than one second when the yacht is at dry shore, because this can damage the electric motor seriously.
