Re: Bow thruster seal for SM
Thanks for the tips. Thanks also for the video which is really helpful. We do have the rebuild kit on board in case we have to fit it.
Vamos a ver.

Subject: Re: [AmelYachtOwners] Bow thruster seal for SM
Hello Ian and Judy,
I rebuilt my bow thruster twice. The first time was in Trinidad, and the second time was in New Zealand 18 months ago. I made a video about the bow thruster https://www.youtube.com/watch?v=F-xWzNfnWLw
The previous owner of Aquarius had left a spare shaft from Amel on the the boat, so in New Zealand I replaced the shaft and the seal. Just replacing the seal with a smaller diameter inner measurement will probably not give you the proper fit. I would have the shaft machined down to the point it's smooth and get the proper sized seal for the final measurement after the shaft is completely smooth. I replaced mine, but one of these days I will have the old shaft machined and purchase some properly sized seals so that I have a spare shaft. After seeing what happened to JP's boat, completely rebuilding his bow thruster in New Zealand as well. I decided to purchase the entire gear, shaft and bearing set from Maud. I now have this as a spare on Aquarius. Thus, I can rebuild the bottom end of the bow thruster in an afternoon with the parts on Aquarius. No machine shop required.
Paul also did a rebuild video of the bow thruster bottom end. https://youtu.be/6zRPHvzMvtg
And he had the kit from Maud which he shows in the video. And he did his at anchor.
After I replaced the shaft in New Zealand, I have had no leakage. I am now on the hard in Thailand, and everything still looks great after 18 months and going from New Zealand to Thailand.
All the best,
