The bow thruster is not driving.

The thruster goes up and down as normal but makes a grinding noise when the toggle drive switch is operated. The propellers do not turn.

I dived on the thruster and the propellors are free there is no debris but the propellors do not turn.

The thruster was serviced by Amel in Hyeres 3/7/17 and since then it has only gone to Golfe Juan. ( 50 miles )

I cant find technical information or a reference in the handbook.

I'd be pleased if anyone has suggestions or information to share.

Many thanks,

Gavin
