Bill,
'That gear you show is the spur gear. The worm gear is the one attached to the motor shaft. In my experience (as per your photo) it's the spur gear that wears not the worm.

Worn Worm Gears in Furling Gearboxes

greatketch@...
 

A question came up a short time ago about how much wear was "too much" on the brass worm gears in the Leroy-Somer gear boxes used on the SM mainsail furlers.  At the time there were no good answers posted.


I have been servicing mine, and had the opportunity to compare my installed worm gears (which are relatively new) to much older ones that had been replaced by the previous owner and put in the emergency spare parts box.  The criteria to look for was immediately obvious with new and old side by side.


The attached photo will show the difference.  The new worm gear has flats on the top of the teeth (on the right in the photo).  As the gear ages it loses material from the sides of the teeth, and the teeth get thiner, eventually wearing until they are sharply pointed on top (on the left in the photo).


A good criteria to use for replacement would be when the teeth first lose that "flat top".  After that, wear will accelerate.  As the teeth get shorter, the worm engages less area on each tooth of the worm gear. As the teeth start to get shorter, the risk of them failing to mesh properly with the worm becomes higher.


I am sure a Leroy-Somers factory technician would have a more sophisticated criteria, but this seems a reasonable answer for our application.

Speaking of anchors this baby set me back my first born but he was an ingrate anyway. My first Amel and she deserves it. I have used the al. Version with never an issue. The guy has one more for a good price.

Re: [Amel Yacht Owners] Re: Speaking of temperatures and alarms

Ian,

The anchor I like is a Mantus.  Similar in looks to a Rocna, in my experience the Mantus sets even faster and (when needed) on a shorter scope.  If you follow the  Manus recommendation for sizing, you'll have an anchor with a larger surface area buried in the seabed, which is what counts for keeping the boat in one place.

How much better than a Rocna?  That's hard for me to quantify. The difference is not huge, but I think it is very real. Obviously none of us have much experience with the different anchors--at the same time--in the same place--from the same boat.  But I have used both quite a bit.  

I would say the Ronca always sets and holds the first time every time.  Well... except for that time in the really soft mud in the Harness River, oh, and that time in the shallow sand in Bottom Harbor, or that time...  You get the idea.  It is perfect, except when there is a good reason for it not to be.

The Mantus has no "excepts" for me in that story.  Someday, there will be some, I am sure. Nothing is really perfect.

The only other anchors I have personnel cruising experience with are CQR and Bruce.  They, of course, work most of the time, but they don't come close to any of the modern designs under most conditions.  There are lots of others I can not say good or bad things about because I have not used them.

I think by the time you are done shopping, this is such a competitive business, prices are not very different.

Hi Craig,
I'll have to look it up when I get back to Kristy.  It has an arm that hangs down into the hose and is deflected by the flow of water.  Decreased flow->no deflection   ->alarm sounds.

Re: [Amel Yacht Owners] Plug 12V Sharki [1 Attachment]

Mark Pitt
 

This is an Italian Type L grounded plug/socket standard, CEI 23-16/VII, that includes two styles rated at 10 and 16 amps.  The Amel ones are 10 amp.  I have purchased the Btinico brand of these plugs ( both in the US and in Europe) when I have added fans and other devices.  It is easy to make a pigtail to convert from this plug to standard 12 volt banana plug.

Anybody knows what kind of plug fits into the tree-pin plug socket of the Amel Sharki?
Picture of the plug socket attached. There are 3 such sockets, one in the front electric panel for the mast electric, one at the main electric table and one in the after cabin. Each has 3 pins with (+) in the middle and both (-) left and right.


The locations of the plug sockets are rather small to change these sockets for a usual modern 12V round shaped socket.

Kent - 
I would like to echo Craig’s inquiry - we’re very interested in knowing what alarms you found worked well.  Do you have any photos of the set up?

Thanks for sharing your experience.

Re: Bilge Pump Quit

Craig Briggs
 

HI Ken,
You don't describe how the gear is broken. If the problem is that the gear portion is sliding on the inner disc it is an easy DIY fix - search my earlier posts on how to do it. Even if the gear ring is broken you may be able to fix it in similar fashion.
Good luck,

Our bilge pump was running for what seemed a long time.  So I went down to see what was up.  I found the motor running, but not pumping.  The motor drive a plastic gear that broke.

Does anyone know where I can get this part, or maybe I have to get a new bilge pump.  :)

Hello,

In the meantime, Amel sav have confirmed the running rigging measurements for Amel54,  if anyone interested. Have not compared to the SM ones.
Currently in French... but will aim to provide a translation when i get the chance to do it.
filed under running rigging folder in files.

Remember that Amel designed the mainsail and mizzen sail halyards to be less than full length...they are designed to be used with small line attached to lower and raise the main and mizzen.

Dear all,


After owning the 1981 Maramu called Popeye for 7 years we have just sold her to an Australian couple called David and Maddy Baddiley who will take her to Brisbane. She was listed on the market for 4 weeks.


Thank you to those who have given advice since we bought Popeye. Work commitments mean we haven't had time to use her this year and it is such a shame to leave a boat like that sitting in a marina berth.


We hope to one day have an Amel again when we have more free time.


Thanks again for being such a good forum.


Best wishes

Re: [Amel Yacht Owners] Bilge Pump Quit

Dominique Guenot
 

This same Bilge pump plastic membrane got punctured twice in 2 years on Viva which gave me a lot of grief. Also based on this distribution list it seems a never ending story.
 
I replaced the pump by a Jabsco waste pump 50890-1100. 
The benefits are: 
- the suction is stronger, does not require a joker and I extended the pipe to empty the bilge minus 2cm; which is handy at the time of bilge cleaning.   
- the pump is small compared to the initial one.  
- 18 months later, so far so good. 

Full disclosure the previous owner had already installed the same Jabsco pump with a floating sensor in case of bilge overflow. I can force them to work concurrently and also I tweaked the wiring so I can switch from one pump to another as needed. I like a lot this redundancy.  

Hope it helps

Manual Mainsail Furling Gearbox

Duane Siegfri
 

I have a "for parts" manual mainsail gearbox if anyone is interested.  The top bearing was rusted out and the top of the outside case was damaged getting it out, but it still appears functional.  It will need a new thrust bearing on top, a new bearing on the bottom, a new oil seal on top & bottom and a wear sleeve at the upper oil seal (due to pitting of the shaft).

Re: [Amel Yacht Owners] Re: Engine exhaust hull fitting and copper water lines [1 Attachment]

James Alton
 

John,

   Silicone caulking can withstand considerably more heat than the polyurethane such as the 3m 5200.  For a bit more money you can buy silicone caulking such as the Dow Corning 3145 which has considerably more strength than the generic materials but it will be considerably harder to remove by either the Ocean or yourself.  Unlike polyurathenes, heating the parts that you want to separate does not work well with the silicone caulking which might be a consideration.

Best,

Subject: Re: [Amel Yacht Owners] Re: Engine exhaust hull fitting and copper water lines [1 Attachment]

 

Spent the morning and good part of the afternoon attaching the new exhaust hose to what I am calling the Amel thru-hull adapter.  In the photo it is the metal piece.  The new hose had the same OD as the old hose and is wire re-enforced.


I used 3M Marine silicone between the hose and the adapter.  It acted as a lubricant during installation and as a sealant after it sets up. While not normally a sealant I would use at the waterline silicone was used previously and did not leak, and I believe Olivier said silicone was what Amel used during production.    A consideration is that unlike 3M 5200 or 4200 siliconed parts can be separated later.  

The fit between the hose and adapter was breathtakingly tight.  As you can see in the photo I had to make use of a ratchet strap to finally pull the fitting onto the hose.  Tomorrow with help from my XX chromosomed  assistant we will clean out the hull fitting and reinsert the adapter plus hose. 

I purchased an extra hose clamp that I intent to fasten about where the one is in the photo and attach a wire between it and the shelf over the thru-hull to lock the exhaust assembly in place.
