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.
