But the thruster engine is completely dead, no response at all.
My best guess is that the bow thruster is installed with the boat at year 2000. The product is Vetus 80 kgf - se attached technical details.
What is the recommended action?
A total replacement of the thruster system or just the thruster engine ( maybe product too old)?
Many Thanks in advance!

Electric motors are not forever
parts that never require
maintenance, contrary to the way people treat them.
First, check right at the terminals of the
motor for
power when the relays are activated to be sure everything on the upstream end is right.
If you have
power, remove the
motor. Before you do anything else, check the drive train to the
propeller. If it is free to turn, you know can suspect the motor. Could be lots of things. Have you ever inspected/replaced the
brushes? Maybe the windings have a short? Bad bearings could be frozen.
Take the motor to the local shop that services electric motors. If the cause of the problem is not serious
corrosion, they will likely be able to
rebuild it to good as new. Electric motors do not die because they get "old". They can have fixable problems however. Industrial motor shops are pretty common.
