Re: [Amel Yacht Owners] Bow truster vibration


Alexandre Uster von Baar
 

Just a guess:
when you are going to Port it is ok, but if you are going to starboard you have the noise and vibration.
If this is the case, I would guess that the “hub” is getting old and stats to look like pictures 4 and 5 on this link
http://nikimat.com/bow_thruster_lost_propeller.html
You will see, the red arrow pointing to the hole that, with age, become wider.

So (if I am right) why not making noise going to Port, because the propeller is pushing the foot of the bow thruster, while going starboard it is pulling on the hub, etc.

Please keep us posted as what you find!

Personally I carry lots of spare hubs, prop, etc...

My bow thruster is making a loud
unusual noise and vibration , but in only one direction . I
was preoccupied with getting it into a travel and failed to
make note of which direction it made noise. Any thoughts on
what would make vibration/noise in one direction. I now wish
I had left it down to take a look . It was only out for ten
minutes for the surveyor to inspect the hull and once again,
I was preoccupied with the task at hand to determine
anything concerning the bow thruster. I will have another
chance in a couple of weeks when its pulled again to switch
out all the transducers. I ordered a new hub and screws from
Maud to be ready, if needed.
Thanks, Pat SM
