Re: Bow thruster seals

Danny and Yvonne SIMMS
 

Hi all,

I find it hard to understand why vessels built the same have such different experiences. Some never leak and some cant stop leaking.

However there may be a clue from many previous posts discussing how to get the right amount of lift by the electric retraction system. This seems to show an expectation that this motor will lift the thruster to its full retracted position allowing the insertion of the retaining pin. The retaining pin has a threaded adjustment so it can be made to suit where the motor has lifted the thruster to. However, the foam seals, to work, need pressure applied beyond that which the motor can achieve. (those who try may explain the number of burnt out motors). I have mine adjusted so the motor lift stops with the seals in contact. However at this point I have a "half hole" situation for the pin. I achieve the insertion of the pin by a strong sideways pull on the lifting cable and the tapered end of the pin assists this as I push it in. This results in good pressure on those foam seals. I have at times left a marina and motored down harbour with the thruster lifted but the pin not in and had significant leaking which immediately stops when I do the final lift and insert the pin. This confirms my experience that good pressure on the foam seals is needed for them to work. The lip seal is important too but without the foam seals working properly there is a huge hydraulic water pressure upwards as the boat pounds into a seaway that overcomes the lip seal.

That's my take on this.

Danny

Hi Jose,

I’d also be interested in some of these seals, as water intrusion in spite of good bow thruster maintenance has been an on going problem for us. On our 31 day passage from Panama to Hawaii we had fairly bad leakage, and I built a mountain of modeling clay I had on hand around the shaft to stop it. That will completely stop the inflow for about 10 days until the clay gets saturated, and you have to pull it off and put some more on. I’d recommend everyone keep some on board for emergency repairs on long passages, as it beats the heck out of bailing water several times a day. The best solution might be your new seals, and I’d love to give them a try.

Hi Jose,

In your original email you write of  having bought two seals and " installing them". Presumably you only installed one, replacing the 60-80-12 that Amel fitted ?

 Incidentally, to save you the  hassle of buying  a number of seals and then sending  them on, I'm happy to buy direct, in which case could you let me have the part number ?
 Equally, I'm happy to add to your own order if that helps to speed up supply.

Dear friends:

After I bought Ipanema 10  years ago we had two years of struggle trying to prevent the leak of water through the bow thruster.  About 8 years ago we had a long discussion on this forum about the bow truster seals which I had changed several times following all the recommendations given by Amel, including adding a third bottom donut seal to increase the pressure.  It was all at no avail.  So, before our transatlantic on 2012 I came up with a brute force solution adding an extra removable sealing system that was wrapped around the shaft and had to be secured after the bow thruster was fully retracted.  This worked very well during the trans Atlantic passage (not a single drop of water) and gave me the security of knowing that in addition of the sealing effect, the shaft was being held by one redundant mechanism. 
As we came back to Boston, we kept using the method but it became very inconvenient to mount and dismount the contraption every weekend when we left and came back to Constitution Marina.
My interpretation of the problem was that due to uneven wearing of the surfaces that guide the bow thruster up and down motion, it resulted in a misalignment between the shaft and the sealing surfaces.  This misalignment  caused a small deviation  of the shaft from the centerline which pushed the lip seal sideways and, because the Amel recommended seals are made of a hard material, it opened a point of water entry. 
I proceeded to test my hypothesis and ordered two special seals made of silicone from a soft seal manufacturer (SSP Inc).  It took several months to get them due to the small number of units I ordered (just 2) but, after I installed them three years ago, I had no more leaks and my bilge has been dry ever since.  The cost for the two seals was $72.50 and, more importantly I have not had to change them or the donut seals since I installed them. I have checked them and the donut seals and they are all still in good shape.

As I am preparing Ipanema for our long term cruise, I am ordering a few spares to carry with me and I will be happy to order some extra ones for any body that wants to try them.

Dear Mohammad and Aty

Would you be willing to let me or us know the cost from ACMO?
This seems very tempting to do myself? Then have a rigger double check. A lot of work, yes but interesting and tempting!

Many thanks.

Hello Nick;

We are currently going though the same process and we have just released the order to ACMO.

If ordered from ACMO, you will receive the entire parts required for the upgrade. This includes a “stronger” pin, as ACMO puts it, the turn buckles and threaded eye. I just again reconfirmed this with ACMO. If you look at your connections at the chain plates, the parts have an ACMO stamp on them.

Therefore according to ACMO, no other parts will be necessary, it is just a matter of removing the existing shrouds and installing new.

I will provide an update if we find anything that contradicts this during the install.

Further to the news that the Amel 54 should have 12mm aft lowers not 10mm and that the intermediates should be beefed up from 8mm to 10mm. I am now seriously working this out.
On the face of it I can order the replacement wire and fittings from ACMO in France and have it a week later. What worries me is that the pin sizes will increase (I guess)
This should be no problem at the bottom where there is a massive chainplate that I could drill out to accept the bigger pins but at the top at the spreader bases it will be tricky.
Has anyone been there and done this project?
What about sticking to 8mm and 10 mm but upgrading the wire quality to say Dyform? Dyform offers about 30% more strength than standard 1x19?
Any experts out there?

My Santorin does not have that line fitted. I will check on the lever on the pump. It sounds like a good idea to fit one and put a dash of red paint on it too.

On another topic - do you still have the fuel dipstick? I can only fill my fuel tank up to the 360 litre mark. I can see the diesel in the neck of the filler pipe so I know it must be full. I just wonder if Henri designed it to have a 40 litre reserve.....

Hi Bill,

Previous owner had installed a cable shut off pull--just Google "cable shut off pull" or you can buy them on eBay.....the red pull handle is right under the helm seat and he had just drilled a small cable diameter hole straight down into the engine room and then to the manual fuel shut off lever thingy on the engine....cable is not in the way of anything.  We went through a period when our red Yanmar stop button did not work (fixed with CorrosionX) and it was pretty handy!  There are plenty of situations where you don't want to have to climb down into the engine room to stop the diesel engine. I can send pics but it is pretty straight forward.  

Blocking the air intake is necessary if you have a diesel runaway (where the engine begins to consume the crankcase oil).  The electric or manual fuel shut off will not work in that situation.  I just hate it when that happens!

Earlier on in my passage from Madeira I had a problem with the Genoa furler. It turned out to be the motor. I switched it for the staysail one which is like new, so I could carry on my voyage.
Now I need to decide how to proceed. The defective motor is shorting on its windings and I can see a strand that is actually broken.
The question is:
To send to rewind shop for repair
Or to buy new?
Or to buy one from another Amel owner who has upgraded to newer better furlers and who has the old ones?

Hi Jose,

In your original email you write of  having bought two seals and " installing them". Presumably you only installed one, replacing the 60-80-12 that Amel fitted ?

 Incidentally, to save you the  hassle of buying  a number of seals and then sending  them on, I'm happy to buy direct, in which case could you let me have the part number ?
 Equally, I'm happy to add to your own order if that helps to speed up supply.

 Thanks,

 Ian and Judy, Pen Azen, SM 302 Greece

Dear friends:

After I bought Ipanema 10  years ago we had two years of struggle trying to prevent the leak of water through the bow thruster.  About 8 years ago we had a long discussion on this forum about the bow truster seals which I had changed several times following all the recommendations given by Amel, including adding a third bottom donut seal to increase the pressure.  It was all at no avail.  So, before our transatlantic on 2012 I came up with a brute force solution adding an extra removable sealing system that was wrapped around the shaft and had to be secured after the bow thruster was fully retracted.  This worked very well during the trans Atlantic passage (not a single drop of water) and gave me the security of knowing that in addition of the sealing effect, the shaft was being held by one redundant mechanism. 
As we came back to Boston, we kept using the method but it became very inconvenient to mount and dismount the contraption every weekend when we left and came back to Constitution Marina.
My interpretation of the problem was that due to uneven wearing of the surfaces that guide the bow thruster up and down motion, it resulted in a misalignment between the shaft and the sealing surfaces.  This misalignment  caused a small deviation  of the shaft from the centerline which pushed the lip seal sideways and, because the Amel recommended seals are made of a hard material, it opened a point of water entry. 
I proceeded to test my hypothesis and ordered two special seals made of silicone from a soft seal manufacturer (SSP Inc).  It took several months to get them due to the small number of units I ordered (just 2) but, after I installed them three years ago, I had no more leaks and my bilge has been dry ever since.  The cost for the two seals was $72.50 and, more importantly I have not had to change them or the donut seals since I installed them. I have checked them and the donut seals and they are all still in good shape.

As I am preparing Ipanema for our long term cruise, I am ordering a few spares to carry with me and I will be happy to order some extra ones for any body that wants to try them.

I missed taking pix before installation but here are pictures of them installed, before and after adding the top donut.

Cheers,

Re: TMD22 Emergency Shutoff

 

Craig,

Well, maybe we are both right. 

There is a Volvo part with a pull cord, but not as foolproof as what the captain installed on your SN😀.

Actually, I can't believe this part! I am sure it is expensive from Volvo!

Dear Amelians,

I have to remove the foot of the bow thruster while in the water and was happy to found on board the Amel special tool to do the job. Comparing the version I have with the photo's on this website I notice that mine is a little different. A stainless steel end to slide into the tube with two much bigger holes. Too big for setscrews. How to connect this version to the tube? May be this is a stupid question, but I really don't have an idea. Are there Amel owners with the same version? Please have a look at the attached picture.

Thank you all for the information provided. The problem is solved. Setscrews set against the stainless steel of the tool. I used three.

Re: Question about the Amel bow thruster removal tool

 

Thomas is correct.

Early model tools had a Stainless end, later model tools had black plastic. Early model tools were designed with holes larger than 8mm, with the set screws designed to be threaded into the bow thruster tube and through the hole in the tool. Later model tools with the black plastic had grooves for the set screws.

My guess is that what you have is exactly what you should have. Please also refer to my earlier photo.

My tool is identical, except where you have stainless, mine is rather flimsy plastic. My memory is that the set screws indeed thread through the bow thruster, and just go into the whole in the stainless; they don’t have to thread, but will provide support.

Just be sure to waterproof all holes and seams; I use both tape and Molykote.

Re: Question about the Amel bow thruster removal tool

 

It is possible that what you have is not made by Amel.

Here is a photo of the Amel-made tool and set screws:

The above is for a SM, I am not sure if it will fit a SN.

Re: TMD22 Emergency Shutoff

 

Craig,

Photo when you get a chance. 

My problem was someone else was asking me by phone. I knew where it was, how to operate it, but didn't have a drawing or photo to send to him. And, by phone, I couldn't describe it well enough for him to find it. In his case it wasn't painted red. Additionally, the manual I had did not have an illustration. Fortunately, Kent emailed me a drawing.

Craig, I believe the stop cord was a Volvo option, at least I remember reading that yesterday.

It is important to not only know where the lever is, but to ensure it is painted red and you have tested it. The Yanmar(s) and Onan(s) mechanical shut offs are painted red. The Volvo D3 has a red stop button on the stbd top side of the engine. 

The Onan will shut down when Master Battery switches are turned OFF, or either the red Emergency or 12 volt switches on its panel are turned OFF. Like the Onan, the D3 requires 12 volts to run, but it will not shut OFF with the Main Battery Switches turned OFF because the D3 will self-power from it's 12 volt alternator.

Bill and all,
On our SN there's a light line (or cord) tied to the hole in the injection pump lever and run to a hole drilled in the lip of the engine room hatch opening. You just lift the hatch and pull on the cord - no need to go anywhere near the engine.  I'm next to certain that Captain Henri installed it himself.
