Re: Amel Maramu replacement waterlock

I made some inquiries with Uship and they indicate that the VETUS HD WATERLOCK / SILENCER TYPE NLP, 50 MM, 10 LITER, BLACK is also suitable for sailing boats. I think I'll go for this waterlock/muffler. Nicely round in shape and I can place it nicely in the corner low in the engine compartment. I'm still unsure about the big one, but I think it's better to be a little too big than the 4.5 liter, which might be a little too small.

We also have an older Maramu Hull #75 , we have a SS Muffler which has served us well , however the welds started to develop “ pin holes “ creating small leaks - we had the welds redone a couple of years ago and now the problem has started again ..

Now also thinking of replacing with a Vetus Muffler .

Trust the above is good for thought.

I agree with that absolutely....if you overheat the engine for whatever reason, it will have enormous consequences.
No manufacturer can guard against that kind of issue.
So, if you had a SS waterlock that wouldn't melt from high temperatures, there would be no sign of trouble and then your engine would be f....ed.
So, you add temp monitors to alarm if the temp gets too high....
Why not just do things properly?...like CHECK the seacock is open before you start the engine, maintain everything properly, check all the hose connections regularly, be sure all the water pathways are clean on a regular basis.
Sure, things can go wrong no matter how meticulous you are, BUT at least if you ARE meticulous any issue should be minor and solvable before it turns into a catastrophe.
We have no problems with our Vetus waterlock...18 years on....

Re: Autopilot and other questions

Hi Ben,

We are also proud owners of an Amel Maramu hull 171. We are preparing the boat for our world trip. We were also looking for a backup autopilot. I think there is not enough room on the back of the rudder for a linear drive. We have decided to install a Hydrovane so that we immediately have an emergency rudder and can also have our boat steered when our electrical systems are out, for example due to a lightning strike.
 
If I can help you with anything and if you want to exchange experiences, my email address is dekoer@....
 
We are doing a complete refit and are on the boat every day. If you have any questions let us know.


Re: Amel Maramu replacement waterlock

Dirk Hazenoot Maramu Huli 171
 

Amel friends you have rightly scared me. There will be no Waterlock LSS 50 on our boat. Now I'm looking further because we need a new waterlock our original Amel waterlock has rotted through. I see that Vetus also sells a VETUS HD WATERLOCK / SILENCER TYPE NLP, 50 MM, 10 LITER, BLACK this is resistant to high temperatures. Now I just don't know if a waterlock with a two-chamber construction is suitable for sailing yachts due to leaning. And I also wonder if 10 liters is not too big. Or does a large volume not matter with a two-chamber waterlock. I hope someone can tell me more about this. I would also like to thank Eric and John for their response.
 
PS: John is your boat still in Port Napoleon? We are on dry land in Port Napoleon. We are refurbishing our Maramu for our world trip. New engine, new rigging, electrics, paint system. If you are in the area, I would like to meet you and share experiences.

I have one on my Santorin. No issues. When clearing out weed from the raw water strainer I forgot to open the seacock again. But I had fitted an inexpensive high temperature alarm to the exhaust pipe just below the exhaust elbow. I stopped the engine immediately to open the seacock. It saved me unknown damage. I believe Bill Rouse posted a recommendation about these a couple of years ago. The issue isn’t about the material the water lock is made from it’s about early prevention of an overheating engine.

Dirk,

Last year the yard in Port Napoleon changed the hoses for our Yanmar. We never asked for that.

In doing so they  cut the hose of the vent loop with a 45 degree angle and put one clamp instead of two. The hose was disconnected after 15 hours of motoring simply because the clamp was not gripping and was not tight enough.

The vetus waterlock melted very quickly simply because the water was not flowing through the exhaust anymore, but directly in the bilge.
I found a Vetus as a temporay repair but I need to find a SS one ASAP.

Result: expensive mess.

Amel Maramu replacement waterlock

Eric Freedman <kimberlite@...>
 



When I bought Kimberlite from Amel, I noticed the Vetus plastic mufflers. I ordered spares before I left the dock. Sure enough 3 years later we were motor sailing and a crew member said I think there is something wrong in the engine room. There was black smoke coming out of the galley sink.



I opened the hatch and could not see the engine. Just as I turned off the engine the hi temp engine alarm went off. If you look back in the Kimberlite photos you will see the melted Vetus Muffler. I used the cockpit shower to cool down the burning muffler. The raw water pump developed a small air leak and it took a while to set off the engine alarm but melted the muffler. I put in my spare muffler and when I got home I had a marine fabricator make a metal one for me.



I also bought a Borel high temperature alarm. It is simple to install It wraps around the exhaust hose of the engine.



You can boil water in a paper cup as long is there is water in the cup.

I asked Furuno this exact question and the rollover problem is solved until July 16, 2039. For me, that is good enough.

http://www.furunousaforum.com/viewtopic.php?f=13&t=9575

To get our AIS and B&G data over wifi, we bought a cheap ($89USD) Yakker2 wifi gateway. My anchor alarm is an old android phone that runs an anchor watch app and uses almost no power.

I am sure a full system replacement yields other benefits, but I would not discount the ability to continue to use your existing system. Frankly, I have tried out the latest and greatest and still think using a keyboard and mouse on Opencpn beats them all.

This is because this unit has an ‘always on’ stand-alone anchor-watch function (and it’s own independent alarm), plus it provides a WiFi access-point that broadcasts a N2K datastream that can be accessed and used by tablets, phones & computers (such as OpenCPN).

Re: B&G Nad-3 Vs H5000 autopilot on Amel

heinz@quetzal.berlin
 

Hello
I installed the Nad 3 2 years ago in New Zealand on my one. The first was unfortunately defective but was immediately replaced by B&G. I am unfortunately only 6 weeks with him sailed because I then flew to Germany and the Kiwis no longer let me in. Corona.
I was very satisfied in all weathers. It is also nice that you can set the course with the plotter and the autopilot follows it. With larger course deviations he asks of course whether he should change the course. Safety query. Functioned flawlessly.
Cheers Heinz.

Hello,

After my previous treat on electronic brands I more or less have decided to go for an all B&G solution. Next question is what autopilot should I choose.

Does anyone has experience with the B&G nad-3 on their Amel? Are you happy with the steering capabilities? Especially is strong winds, gusts recovery, high waves etc.

From paper I prefer the nad-3 over the H5000 because it's a more out of the box solutions and it requires less calibration. But the H5000 is more advanced.

So I wonder how good are the out of the box capabilities of the nad-3 on a Amel ketch rigged sailing vessel.

Thanks for sharing your experience. I really want to make sure I buy the right stuff.

Kind regards,

Hello
Since yesterday when I tried to park in a box in a marina in Auckland my bow thruster motor failed.
If I turn the beam to the left or right the whole power supply breaks down for a moment. After that the power is back.
I took the rudder off and it can be turned perfectly by hand.
But the same happens with the engine. No power for a few seconds, all instruments off, no rotation of the motor.
Does anyone know this problem.
Does anyone know how I can find out if it's the motor or maybe a relay that doesn't work.
Can I test the motor without a relay, maybe on the 4 cables marked D1, D2, and A1, A2?
I am grateful for a quick answer.

Hi Ruedi,

 

This is my email from 2019.

 

 So the chest fridge that is accessed from the counter top, I have the big one. Did die on me in the Canary Islands. I diagnosed it to be a complete loss of R134A. 

I checked the evaporator plate in the fridge  itself and decided that was fine. Then looking underneath where the compressor is located I could see a crack on the soldered joint to the compressor itself. Removing the access grill panel was easy but I could see that there would be no way of removing the compressor without taking out the wood bar below which I neatly cut.
It then unscrewed. Allowing the whole compressor to come out.

Then with the compressor out on the floor of the little bilge there I managed to get a fridge technician  

to re solder the joint. Vacuum the system, and I paid him extra to leave the vacuum pump running a whole hour,  before recharging with gas. It is important to get the right amount of charge, so just enough gas so that the evaporator frosts up but only to the top not back to the compressor. Then I repositioned the compressor in its old location back on its rubber mounts.

All is well. We have had no further problems, touch wood.

Nick

Hi Ruedi,

 

from my point of view on your issue, I recommend to get in touch directly with VECO, the OEM of the fridge and cooling systems on our boats. The company is located in Italy and are well known by their outstanding and very helpful after sales and service support.

Email or better: by phone directly. My own experience and from another 54er Amelien too.

My thought: all these A/C and fridge devices are nothing for DIY.

 

 

NB:

End of each season I flush all my A/C lines and systems overnight with a solution from citric acid. Next day all the sludge and salt clogs will leave the system as white sauce, and everything is clear.

Under the season, every 2 month I flush the Systems in the same way with 5 liters of white vinegar, regular service. Simple and easy.

 

Our frigos and freezers are water-cooled with fresh water, expensive but reliable.

Our entire freshwater system will be cleaned end of the season with a solution of citric acid too: 1kg solved in a bucket, poured into 200 liters in the (freshwater) tank, then flush all taps, showers outlets, all frigos and freezers on for short time. If it smells strong as lemon juice.

Let it rest for half a day and after, empty all lines in the same way. Then flush them all with fresh water. May by, your fresh water smells at the beginning a little bit like limonade. No harm! Top up your tank to full.

But all your lines and outlets are free and clean.

 

Next step: From these season up, we´ll start to fill dock water first thru an double water filter and then thru a water-softener. Hope we will never get residues and calcification on board.

 

Hope the best for you and stay safe!

Hi Thomas  

 

Thank you for all the useful hints. I still get into more detail’s with your information. You are right with the Engineers changing expensive gas and drinking your coffee 😉

BTW: I searched but was not able to find Arnos treat “Access to the galley fridge/freezer compressor has been explained by Arno”. ??

 

It sounds like a blockage as you described. Either by Ice or the filter drier is blocked (the Engineer was pointing at this as well). But I don’t know where is this filter located and how can I change it. The “Engineer” said he need to remove the compressor, but it’s not possible to move it out under the fridge in the galley.

 

As soon as I knock on the evaporator with my fingers I hear a hissing sound and the evaporator will frost promptly but only for a very short time. After that noise stops again, compressor sound still there like normal, and if I wait for an hour or longer so the fridge goes up to 10 or more °C. The evaporator is cool (not cold) and sweaty. The compressor works normal to my impression; littles sound, between 35-40°C warm is cooled by seawater which is about 17°C. (I measured the compressor and the cooling circuit by a laser gun). At the moment the compressor runs with about 2500 rm and consumes ca. 55W.

 

Early this week before the local “Fridge-Engineer” changed the gas, same situation but the compressor started to increase rpm. Now the compressor works constantly but not cooling down? With my little knowledge I think the Compressor side works normal, but not on the gas/evaporator side.

I will make more homework and will let you know, any other hints where the filter is, or how to remover the compressor are welcome.

Betreff: Re: [AmelYachtOwners] Galley fridge intermittently cooling

 

Hi Ruedi,

 

I got to learn a lot about refrigeration since my last post. 

 

Intermittent cooling can be caused by a blockage in the refrigerant circuit. I find that the best way to confirm that is to measure the power consumed by the compressor. Either with an amp meter or better with a wattmeter that will show voltage, amps, watts, max amps, max watts, total watts, total amphrs. They cost a handful of dollars on Amazon / AliExpress. 

 

A blocked circuit will show the compressor consuming lower power (only 20W instead of 60/100W, but constantly). The evaporator will be cool (not cold) and sweaty. Stop/Start of the unit may cause the compressor to stall (stops itself, waits 30s and tries again), emitting the corresponding error code on the diagnosis LED (if you have one plugged in). The fan runs continuously during that sequence, which can be mistaken for the compressor running. Learn to recognise the various sounds. 

 

The blockage can be due to ice crystals or corrosion sludge.  Usually the blockage is on the capillary, the hair-thin copper tube leading to the evaporator plate, but can also happen at the entry of the evaporator, where the refrigerant expands and the temp gets super cold. 

 

Ice crystals form because tiny amounts of humid air can be sucked in on the vacuum side of the compressor at the quick connector.

 

Aluminum sludge can form because of the corrosion of the evaporator plate by the refrigerant chemicals. 

 

The filter drier, located after the condenser (the u shaped water circulation tube sitting on top of the compressor on our units) is meant to catch such impurities but can/will saturate at some point. 

 

It’s difficult to differentiate between solid and ice blockage, but if the unit cools again after you let the evaporator warm up to room temp, you can hope it’s ice based. 

 

You can also gently knock on the evaporator around the thinnest section of the embedded evaporator tube, with a rubber tool or snapping your fingers and hope to dislodge the blockage. You’ll hear a hissing sound and the evaporator will frost promptly. 

 

Ice cristal issues may be resolved by changing the filter drier, vacuuming the system thoroughly and refilling with refrigerant.

 

Solid blockage types are trickier and usually need a change of evaporator/capillary, since they are located after the filter and before the capillary.

 

So there is a risk that changing just the filter drier may not solve the issue.  

 

While you have someone onboard working at welding/brazing a new filter drier, ask them to remove the quick connectors and weld the circuit.  Those quick connectors make it really easy to install the fridge initially but will fail and lead to refrigerant loss, humidity infiltration, and workhours of fridge engineers, some (many?) of them using the occasion to sell complete new fridges.

They are also an environmental nonsense because the will lead to people topping up with refrigerant again and again instead of addressing the issue. R134a refrigerant is better that freon but still an extremely potent greenhouse gaz.

 

A fully closed circuit instead of quick connectors vastly reduces risks of refrigerant leaks. 

 

 

Access to the galley fridge/freezer compressor has been explained by Arno.

 

 

Hope this helps navigating the interesting world of refrigeration/AC engineers, whose charging of 100$ per hour in Tahiti for drinking your coffee (before 10am, your beer afterward) while everybody waits hours for the system to settle/be vaccummed/refill slowly/settles/etc, strongly encourages you to google a thing or two about fridges and potentially invest in gauges (25$), a vacuum pump (more expensive), canisters of refrigerant (only available to license holders in eco friendly countries) and maybe even an 02/propane brazing kit.

 

 

Best,

Hi Amelia’s, (@ Arno & Mohammad)

 

The Galley fridge on my A54 is only intermittently cooling and sometimes it stops completely until I can restart it. A fridge-guy told me; - it is the filter blocked inside the unit and it is a common problem on boat fridges. He mentioned, he need to take out the compressor to change the filter (just a 2€ part). But to take out the compressor on my A54#55, it seems I need to dismantle a big parts of the galley because the “service opening” is too small for the compressor replacement.

 

Does anyone know where this filter is located by any chance?

 

@ Arno/Mohammad, I have found in older treats that you had similar problems and you both changed the compressor. How was it gone and how to change the compressor without too much hazzle? The opening is too small, even if I’m able to remove the big wood panel galley front.

How was it in your case?

 

Thanks and best regards

Hi Thomas,

Ice crystals would occur if the filling of the system was not done properly. There is a filter in the system that binds any moisture that may be left at filling time. Normally they replace this filter when refilling. Once a system is working properly there is no interference with the atmosphere so moisture cannot enter. If the system is leaking you may see moisture enter the system after so much gas has escaped that at run-time the low pressure side gets below atmospheric pressure (depending on where the leak is). If you still have the original compressors (you can see this by looking at the way the speed control works). The newer units use a rotary switch if I'm correct. If you still run the originals chances are you have a gas leakage, most probably at the quick-fittings. These are the screw connectors that connect the evaporator to the compressor.
In my case the problem was a leaking heat-exchanger (the tube on top of the compressor) that rotted away due to the salt water in the circuit. In the end I replaced all the compressors.

Regards,

B&G Nad-3 Vs H5000 autopilot on Amel

Joan Blaas
 

Hello,

After my previous treat on electronic brands I more or less have decided to go for an all B&G solution. Next question is what autopilot should I choose.

Does anyone has experience with the B&G nad-3 on their Amel? Are you happy with the steering capabilities? Especially is strong winds, gusts recovery, high waves etc.

From paper I prefer the nad-3 over the H5000 because it's a more out of the box solutions and it requires less calibration. But the H5000 is more advanced.

So I wonder how good are the out of the box capabilities of the nad-3 on a Amel ketch rigged sailing vessel.

Thanks for sharing your experience. I really want to make sure I buy the right stuff.

Kind regards,

I notified my insurance broker in September 2021 ( SafeWaters Insurance )of my intention of upgrading my older AGM batteries to Lithium. He checked with my insurance carrier and they told him they’d drop me if I proceeded. I’m hopeful that this changes soon.
