Trouble shooting
Electric motor does not operate
- Check that the battery main switch is 'ON'.
- Check whether the control panel fuse has burnt out.
- Check if the main fuse has burnt out.
In all the above cases the 'POWER' indicator lamp will not be
on. Check if it is possible to turn the propeller. A piece of wood
or similar could have been caught between the propeller and
the tunnel.
Electric motor turns slowly
- The battery is flat.
- Bad electrical connection(s) due to e.g. corrosion.
- The carbon brushes are not making proper contact.
- The battery capacity is reduced because of very low temper-
atures.
- Weed or fishing line has become caught in the propeller.
Control panel fuse is burnt out
- Short circuit in the operating circuit; check the wiring.
Electric motor turns (too) fast but there is no thrust
- The propeller blades are damaged because of an object in
the tunnel.
The bow thruster loses oil
- If an oil leak is noticed inside the vessel:
First check the hose and its connections. Check the oil seal
on the input shaft of the tail piece.
- If no oil is seen inside the vessel then check the propeller
shaft oil seal in the cover of the tail piece.
N.B. When fitting the tail piece cover both fixing screws should
be installed with thread sealant (Loctite®).
