Hi Ken,,
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.

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, Ken Powers Aquarius SM2K #262 On the hard in Krabi Boat Lagoon
