Re: [Amel Yacht Owners] Bow Thruster Abuse

Jeff, FYI, The 53 and 54 bow thrusters are entirely different . You are correct that the 54 incorporates a thermal limiter to keep it from going Chernobyl when overused. The 53 has no thermal or overcurrent protection of any kind. When I queried about the reason for this from the guy who designed it, Jacques Carteau , he said that in dire/extreme situations, he thought it was better to lose the bow thruster to overuse than to lose the boat, or severely damage it, due to the bow thruster taking a time out. Personally I prefer Carteaus method. All that said, the bow thruster on your boat was never abused when I owned it but I had to have the motor rebuilt right before I sold it to you as the brushes and the commutator didn’t play nice with each other. It worked fine until the moment it would not work at all. I’m glad I always test for forward and reverse and bow thruster both ways before the docklines come off. The day it failed was very windy and not with any options  to avoid catastrophe if I had cast off. You might not have wanted to buy what was left!

 

Enjoy your Amel, Joel

Hi Paul, if the super maramus  thruster motors are made by sliepner, and they are a side power, as on the 54, there is a built in overheat switch. The switch itself will go (ask me how I know) and the unit will not function. Otherwise it will stop the unit from working until the motor cools again. It can be challenging docking here in le marin when its blowing hard and they cram you in like sardines.  Best Regards.                                                                                                           Jeff Spirit Amel 54 #14

Hello Joel.  Nice to hear from you.

The coatings on the motor are fine.  What came out appears to be just oil.  We just serviced the unit 4 months ago.  I’m wondering if we may have added too much oil during the service although I don’t think so.

Thanks for taking the time to provide your thoughts.

All the best,
