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.

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.

Re: Bow thruster motor.

Andrew & Kate Lamb
 

Hi Chris

I had a very similar problem and ended up having the commutator rebuilt by a local French company that normally services lift motors and wind turbines however one important thing to check is the state of the solenoids - we changed these also, the engineer reckoned the problem was probably originally caused by poor contacts in the solenoids which in our Amel were also in the bow thruster compartment . No problems since.

The Leroy-Somer bow thruster motor on my SM Pure Magic failed with sparks & some smoke from within the commutator cage. There is just one rewind facility locally which I used having heard from Amel that the motor is no longer in production, and there is no reserve stock of motors. After rewind repair of heat damaged armature windings (the field coils were also rewound because of lesser, indirect, heat damage)  the motor was demonstrated to run smoothly, both forwards and in reverse for about one to two minutes. Reinstalled on the boat, having taken every care to make the correct connections to the Albright contactors the motor ran for about a second before showering sparks. Back to the rewind facility, a second repair, followed by a successful test run  and similar failure once again. With options running out, I trespassed into the unknown and  dismantled the top end bearing housing and brush mechanism after checking for continuity ( present ) across the DI/D2 power leads which supply the field coils, but found no continuity across the A1/A2 leads for the armature windings. Checking for continuity across the commutator segments showed multiple connections between segments, but  with no ordered pattern such as you would expect if the current path follows the intended route between conductors and segments. My conclusion is the commutator is shorted in many places and I do not think this is repairable, certainly not locally. 
 I am a new recruit to the forum and have seen a wealth of input on the topic of bow thrusters, but mostly to do with the seals and servicing of the drive shaft and propeller. Somebody must have had to deal with an electric motor problem here or even had to replace the motor. I would really appreciate any advice from the experienced forum as to how to get back to a functioning bow thruster. Thank you for your help,

The engine of the Leroy-Somer thruster is not reliable. I think it is used in dumpsters, you should, I think to find spare parts.
For my part I broke the engine shaft! The breakage was due to a mechanical fatigue of the metal of the shaft which is under seized.
In your case it may be better not to spend too much time repairing this engine and change to a new one.

Re: TMD22 Emergency Shutoff

Jean Boucharlat
 

Yes, stopping the air input does work, but…it can be seriously hazardous to the palm of your hand if you do it by hand as the depression is quite strong. On the other hand (pun intended), if you use rags, they will be sucked into the engine. So some caution is necessary with this method.

Re: TMD22 Emergency Shutoff

Danny and Yvonne SIMMS
 

Hi,

This is not a light weight topic. There are serious dangers involved. First. The comment about shutting off the fresh air supply. I presume this reffered to blocking the air intake. A hand put over this at reves would almost certainly result in serious injury. The suction on a reving diesel engine is considerable. Secondly, in an emergency shutting the fuel off would be way too slow. The lever on the side of the injector oump is the only safe option snd every operator should be familar with this. Diesel engines in some  circumstances can run away rev. Also consider being in the engine room and an emegency happenned, something around the drive shaft, a burst water hose or any thing else that might require instant reaction. I commend to all owners to identify their emergency shut off and practice using it.

Regards

Danny

Re: Water Tube connection

Mark & Debbie Mueller
 

I had a similar problem, the piece disintegrated.  For an interim fix I used a SharkBite fitting available at any hardware store.  I would not use this as a permanent replacement due to the conditions these boats are subject to over time - I believe the SharkBite would fail. I ordered a replacement fitting from FaucetsComplete.com item Zurn QACA33MG Pex Qicktite Brass Male Adapter.  This fit directly into the brass valve body and connected to the factory PEX tubing even though it was millimeter tubing and the fitting was for imperial size tubing. Check your valve body size to be sure the two thread sizes match.

Good luck.
