Nice to see you guys are slowly progressing closer to home. Congrats on your trip so far since we last shared drinks together on Island Pearl in Panama. We look forward to seeing you guys back in Brisbane someday.
I do not have a solution for your problem, so best wait for the smarter engineer folks to wake up in Europe & the USA with good answers to this, which I am sure will not be too hard.
The reason for this note is a suggestion ..... Go down to a local bicycle shop near you and purchase a new rubber inner tube for a large and as broad as a possible bicycle wheel. Take this, cut it across to make a long tube, then cut a slit all the way up through it to form a new long, broad single layer of rubber. Always keep this on board to wrap tightly around the base of your thruster if ever you see any leaks there in the future. It works perfectly and even with a badly damaged seal if that occurs at anytime whilst out cruising. In such an emergency it will keep every drop of water out!
We did this in the Indian Ocean after replacing our bow thruster in the Maldives. At the time we did this in-water, and Amel sent a complete new bow thruster out from France but did not send us a new top rubber ring (the one inside the boat) and hence, although we never ever got water in there at any other time ever, between Chagos and Rodrigues we had huge 6m seas and winds and extreme conditions and en route found about 1 liter per day of seawater getting into the front bilge on that trip. All I could come up with in Rodrigues was this primitive bicycle-type solution, but it worked a treat, and we never had another single drop of seawater till reaching Durban where we were able to lift the boat for all her two-year maintenance, including replacing that all-important top seal. In fact, this system worked so well that it became my standard practice for us to wrap it around that base area of our bow thruster just after leaving the harbor on each and every ocean crossing thereafter "just in case"! Of course, for all local, Caribbean, and Pacific Country cruising we never put it on, but for long crossings, it was a wonderful comfort to have handy.
Best regards to you both
