Subject: Re: [AmelYachtOwners] Bow thruster seals Danny,
I understand very well how the system SHOULD work and, if everything is new, the seals should work as designed. Unfortunately, wear can change the system and, in my case nothing worked to stop the leak, including several adjustments of cable tension, and increasing compression by the pin. As I said in my previous e-mails, I believe the problem occurs because the wear of the surfaces between the hull and the thruster that guide its motion result in a misalignment between the trunk and the seal, causing a lateral force on the lip seal which makes it incompetent allowing water intake. The misalignment also results in the sealing surfaces between the donut seals and the hull are no longer parallel affecting its sealing action. Following Amel instructions and wasting seals, money and time I realized that the problem could be corrected by designing a seal that would be made of a softer material and have lips that could maintain the seal in the presence of misalignment. That solved the problem 3 years ago and I have had a dry bilge ever since.!!
In my design, I used two seals in series: a silicone wiper below and a silicone u-cup on top. This results in a slight protrusion of the seal above the horizontal fiberglass surface, as it can be seen in the pix I sent before. I used silicone glue to secure the seals in place and was planning to add washers to secure them to the fiberglass, but after several months of procrastination, I realized that the glue was sufficient to keep the seals in place. 3 years later, using the thruster twice per week, almost every week during 6 months each summer, including a Marion to Bermuda race the seals are still working as new. Since I add silicone grease to the trunk every year and, given the number of times (~50/year) that I use the thruster, I am expecting that they will last a very long time. So far I have serviced the thruster every year but have decided not to change any of the seals, including the donut seals, which looked in excellent condition.
I just received the quote from the seal manufacturer and it is as follows:
10 pcs. Silicone wiper $ 31.65ea. 10 pcs. Silicone u-cup $ 32.50ea.
This it will be about $65 per set plus shipment and It will take 14-17 business days to ship from the order
so far I have received requests from:
Bob Ross, sv Nomad, Trinidad (1 set)
Ian and Judy, Pen Azen, SM 302, Greece (?sets)
Chuck_Kim_Joy (? sets)
Steve Davis Aloha SM72 Ko Olina, Hawaii (? sets)
Mark, Cream Puff - SM2K - #275 (? sets)
Dan Taylor (2 sets) Gerald Bassin Jetlag, SM113 (2 sets)
Since I want to place the order this week I will appreciate if each of you can e-mail me directly with your e-mail, the number of sets you want and the address two where it should be shipped.
We still need to figure out the cost of shipping to each one of you and how you will transfer me the money, but given that is something we can figure out later.

Hi Jose, that's good you have the anti twist.. Ocean Pearl's seals were leaking badly when we bought her but we replaced the seals when we did the anti foul before we first set off and have never had any trouble since. Bi annual foam seal replacement is all we have ever done and occasionally we have had to do a lip seal between the bi annuals. However we are not heavy users of the thruster.

I hope you guys are doing well and the engine issues are now behind you.
We are replacing all 6 shrouds at the main because ACMO had a crack in one of the original long shrouds that we found in our rig inspection last year.
They did extend a 10% discount because of this so the total shipped to Corfu was 5000 euros.
Off course you only need to upgrade the mid and lower shrouds so your pricing will be less. I did receive a complete quote for all rigging that I will forward to you shortly.
I, like you, try to do everything I can myself, which is about 90%. It’s better to make a mistake and learn while help is available. However, the cruising season in the Med is short so I do elect to use known outside people if necessary so we get to enjoy the season.
The rigging is definitely one of them, at this point, for us. So I’m flying Ricky from Malta to Corfu for 2 days to take care of the shrouds and some lighting and wind cane issues.
Enjoy Tahiti. We chartered there in 2008 and had a great time.

Hi Jose, Well done for finding a solution to your leak problem. However your comment about the wear from use has triggered this question. Do you have the Amel designed retrofit anti twist system. This is a vertical 25 mm tube mounted beside the thruster. There is a bracket mounted on top the thruster motor that engages with this. The Amel service agent in Fort Lauderdale (his name escapes me) told me he had a lot of work fitting these in the 2000's Regards Danny SM 299 Ocean Pearl

Danny,
I understand very well how the system SHOULD work and, if everything is new, the seals should work as designed. Unfortunately, wear can change the system and, in my case nothing worked to stop the leak, including several adjustments of cable tension, and increasing compression by the pin. As I said in my previous e-mails, I believe the problem occurs because the wear of the surfaces between the hull and the thruster that guide its motion result in a misalignment between the trunk and the seal, causing a lateral force on the lip seal which makes it incompetent allowing water intake. The misalignment also results in the sealing surfaces between the donut seals and the hull are no longer parallel affecting its sealing action. Following Amel instructions and wasting seals, money and time I realized that the problem could be corrected by designing a seal that would be made of a softer material and have lips that could maintain the seal in the presence of misalignment. That solved the problem 3 years ago and I have had a dry bilge ever since.!!
In my design, I used two seals in series: a silicone wiper below and a silicone u-cup on top. This results in a slight protrusion of the seal above the horizontal fiberglass surface, as it can be seen in the pix I sent before. I used silicone glue to secure the seals in place and was planning to add washers to secure them to the fiberglass, but after several months of procrastination, I realized that the glue was sufficient to keep the seals in place. 3 years later, using the thruster twice per week, almost every week during 6 months each summer, including a Marion to Bermuda race the seals are still working as new. Since I add silicone grease to the trunk every year and, given the number of times (~50/year) that I use the thruster, I am expecting that they will last a very long time. So far I have serviced the thruster every year but have decided not to change any of the seals, including the donut seals, which looked in excellent condition.
I just received the quote from the seal manufacturer and it is as follows:
10 pcs. Silicone wiper $ 31.65ea. 10 pcs. Silicone u-cup $ 32.50ea.
This it will be about $65 per set plus shipment and It will take 14-17 business days to ship from the order

Subject: Re: [AmelYachtOwners] Bow thruster seals
Danny, I understand very well how the system SHOULD work and, if everything is new, the seals should work as designed. Unfortunately, wear can change the system and, in my case nothing worked to stop the leak, including several adjustments of cable tension, and increasing compression by the pin. As I said in my previous e-mails, I believe the problem occurs because the wear of the surfaces between the hull and the thruster that guide its motion result in a misalignment between the trunk and the seal, causing a lateral force on the lip seal which makes it incompetent allowing water intake. The misalignment also results in the sealing surfaces between the donut seals and the hull are no longer parallel affecting its sealing action. Following Amel instructions and wasting seals, money and time I realized that the problem could be corrected by designing a seal that would be made of a softer material and have lips that could maintain the seal in the presence of misalignment. That solved the problem 3 years ago and I have had a dry bilge ever since.!! In my design, I used two seals in series: a silicone wiper below and a silicone u-cup on top. This results in a slight protrusion of the seal above the horizontal fiberglass surface, as it can be seen in the pix I sent before. I used silicone glue to secure the seals in place and was planning to add washers to secure them to the fiberglass, but after several months of procrastination, I realized that the glue was sufficient to keep the seals in place. 3 years later, using the thruster twice per week, almost every week during 6 months each summer, including a Marion to Bermuda race the seals are still working as new. Since I add silicone grease to the trunk every year and, given the number of times (~50/year) that I use the thruster, I am expecting that they will last a very long time. So far I have serviced the thruster every year but have decided not to change any of the seals, including the donut seals, which looked in excellent condition. I just received the quote from the seal manufacturer and it is as follows:
10 pcs. Silicone wiper $ 31.65ea.
10 pcs. Silicone u-cup $ 32.50ea.
This it will be about $65 per set plus shipment and It will take 14-17 business days to ship from the order
so far I have received requests from: Bob Ross, sv Nomad, Trinidad (1 set)
Ian and Judy, Pen Azen, SM 302, Greece (?sets)
Chuck_Kim_Joy (? sets)
Steve Davis Aloha SM72 Ko Olina, Hawaii (? sets) Mark, Cream Puff - SM2K - #275 (? sets)
Dan Taylor (2 sets)
Gerald Bassin Jetlag, SM113 (2 sets)
Since I want to place the order this week I will appreciate if each of you can e-mail me directly with your e-mail, the number of sets you want and the address two where it should be shipped.
We still need to figure out the cost of shipping to each one of you and how you will transfer me the money, but given that is something we can figure out later.

Hi Jose, Please add me to your list. I’d like 2 sets, too. I’ll be in Maryland USA until November.
Thank you for doing this. If they can ship directly to me the address is 7025 Thorneton Rd Easton MD 21601
If you take the whole shipment and ship them yourself, don’t estimate the cost of shipping...I made that mistake with the door handles :-) Kent Robertson S/V Kristy SM 243 USA cell: 828-234-6819
