Re: [Amel Yacht Owners] Bilge Pump Gasket replacement

Bill & Judy Rouse <yahoogroups@...>
 

Colin,

I had a hard time finding that part. The gear section of the pump is identical to a Mercedes Benz wiper mechanism, but I do not know what year and model. I had someone in Turkey replace the white Delrin gear and he told me that he found it in a Mercedes parts distributor.

I heard that Maud now has this part. Check with her at SAV"at"Amel.fr. I also heard that Riza at Emek Marin in Turkey has the part. Check with him at cagdas"at"emekmarin.com

Good luck.

Certainly from what we are looking at here Mark is correct that there are sufficient small bolts around the unit to hold the gaskets firmly in place. The important issue appears to be ensuring that the gaskets and holding plates all go back on the right way around.

Interestingly in our case the gaskets are in excellent condition but what we have now unfortunately found is a chunk of the little white cog broken with approx 5 teeth missing.  Due to this the motor turns but cannot make contact with and turn the white cog around to push the suction unit.

Has anyone else managed to fix this approx 1.25 cm gap or managed to get a replacement white cog from Amel or direct from the Italian pump supplier? We are without our computer here right now but do remember a comment some time back regarding fixing this with a drill bit which turned out well however our missing chunk is probably too large for that solution.

Any suggestions?

Jim,

 

I think there are plenty of screws to form a good seal without introducing a foreign element. I replaced mine a couple of years ago and did not use any sealants. I made sure the surfaces were clean before re-assembling the pump. I have not had any problems.

 

Hope this helps.

Hope some can give me a little advice on replacing the gaskets on my original Amel installed bilge pump. I have a Super Maramu Hull #207.  I have replaced the gaskets once before but have developed a leak around the gaskets and am wondering if when I replace them this time is it advisable to also add silicone or some other sealer between the gaskets and the pump.  I have ordered the replacement gaskets form Amel and am aware that they have to be installed with one side towards the water as labeled on the Gaskets.

Thank you,

Re: [Amel Yacht Owners] Charging AGM batteries

Bill Kinney <greatketch@...>
 

This is why you should check with the battery manufacturer for charging specifications!  Flooded batteries are pretty much all the same, but AGM varies depending on the details of internal construction.  A few tenths of a volt DO matter in the long run, especially if the batteries are on float a lot.

I just installed a Victron controller with my solar panels. None of the preprogrammed settings were suitable, I needed the "Bluetooth dongle" which allows exact programming of each step of the charging process through your computer or mobile device.

Bill Kinney reports his AGMs are to float at 26.6V (i.e. 13.3V).  

Trojan sternly warned my AGMs need to float at 27V (i.e. 13.5V) and not more, at 25 °C; less voltage at warmer battery temperatures.  Furthermore, my Trojans call for Bulk and Absorption at 28.8, with an absolute maximum of 29.4.

I discovered that neither of my Mastervolt chargers (100A, 30A) nor the Mastervolt alternator regulator offer factory settings that match the Trojan specifications; however, Mastervolt allows the user to use a PC (or a Mac) to program exact voltages as required by Trojan.  

I believe the same capability programming capability exists on Victron.

Thanks for the replies. It seems that the float level of 13.6v is the general consensus. My chargers, Dolphin, which came with the boat, do not have a specific AGM setting. The nearest one is for "sealed lead" which gives 13.6v float but only 14.2v maximum whereas the West Marine website says that AGMs should take 14.7v max. So I guess I'll go with that unless someone advises otherwise.

Re: [Amel Yacht Owners] Charging AGM batteries

Bill & Judy Rouse <yahoogroups@...>
 

Amel installed a Leece Neville 175 amp 24VDC alternator as an option on BeBe 387.

When I was considering going to AGM, I contacted Leece Neville. They told me that the alternator would need to be modified and a smart external regulator added if I wanted to change to AGMs. They said that the alternator would work, but that I would not get the life that is expected with AGMs.

Best,

Because of their internal
construction a full on classic thermal runaway is MUCH less
likely to occur with good agm batteries. Lifeline claims
they have never heard of it happening to their batteries.
You can however, melt them down if the voltage is too high
for too long causing the electrolyte to boil
off. 
Monitoring is
simple. Fully charge, disconnect the charge and load, and
then check voltage after a bit of time to rest. A shorted
cell will quickly pull the voltage for that one battery down
to 10.5. Otherwise, capacity testing and such can be the
same as a flooded battery. 
You'll also see a bad cell in
your charging amps at full charge. They'll never drop
down to the 0.3 amps or so that they should at the correct
float voltage when the batteries are full.

Wow! You were lucky you didn't have a
fire. I don't know the charge settings for AGM
batteries, but whenever you hook your new batteries up you
need to monitor the 30 amp charger closely. It's
entirely possible that you have a fault in your charger.
 This is just another example of why it is so important to
monitor your batteries closely. With AGM's I don't
know how you can monitor the batteries like you would
specific gravity in a flooded lead acid battery. I would
like to hear about this.
Since my last battery
mishap, I have quit leaving my charger on constantly while I
am off the boat. I have instead hired someone to come aboard
once a week to flush the Watermaker membranes and top the
batteries up with a 2 hour charge.

I don't know about your alternator. 

We have the 60amp internally regulated unit, not the larger one that was a commonly factory installed option. 

It runs at 26.6 or 26.7 volts maximum. Not high enough to upset even AGM batteries. But not high enough to really charge them efficiently either.

then check voltage after a bit of time to rest. A shorted
cell will quickly pull the voltage for that one battery down
to 10.5. Otherwise, capacity testing and such can be the
same as a flooded battery. 
You'll also see a bad cell in
your charging amps at full charge. They'll never drop
down to the 0.3 amps or so that they should at the correct
float voltage when the batteries are full.

Wow! You were lucky you didn't have a
fire. I don't know the charge settings for AGM
batteries, but whenever you hook your new batteries up you
need to monitor the 30 amp charger closely. It's
entirely possible that you have a fault in your charger.
 This is just another example of why it is so important to
monitor your batteries closely. With AGM's I don't
know how you can monitor the batteries like you would
specific gravity in a flooded lead acid battery. I would
like to hear about this.
Since my last battery
mishap, I have quit leaving my charger on constantly while I
am off the boat. I have instead hired someone to come aboard
once a week to flush the Watermaker membranes and top the
batteries up with a 2 hour charge.

Hi,
I just came back to my boat
after three months and found that my entire bank of 12 AGM
batteries melted. I had left the 30A charger running. I am
in the processing of replacing them with new AGM batteries
(can't get anything else where I am in Grenada). I have
an Amel 54 #98 with Dolphin 100A and 30A chargers. Would
someone be able to advise which is the correct charge
setting I should  use on these chargers for charging AGM
batteries?
Thanks,PaulS/Y

Re: [Amel Yacht Owners] Charging AGM batteries

Bill & Judy Rouse <yahoogroups@...>
 

Paul,

I am certainly no expert, but every Amel battery bank melt-down that I am familiar with was caused by an internal short in a single battery in the battery bank.

I think that you will find it worthwhile to purchase a digital battery tester and test yout batteries on a regular basis. There are many owners in this Group that have done that and support the concept.

Although it could be your charges or regulators, either solar, or conventional battery charger...the chances are that a single cell in one battery caused your problem. Each of your batteries has 6 cells times 12 batteries is 72 cells, so you understand the possibility!

If I had not sold BeBe, I would be looking at a thermal activated switch that would measure the temperature inside the battery compartment and turn off the charger at a preset temperature. Switches like this are used in commercial refrigeration, heating and air conditioning. Surely some technically inclined Amel owner will try this. It is especially workable since most SMs and 54s have an enclosed battery compartment.

That is indeed something which should also be checked, but the overheating happened when the boat was out of the water so I do not think it was the cause.

Another possibility is the solar panels. I'm not sure what kind of regulators they have.

Re: [Amel Yacht Owners] Charging AGM batteries

Alexandre Uster von Baar
 

Hello Paul,

This was actually a question not really related to your situation, but generally about AGM batteries.
And by the way, sorry about your problem…

I was just reading an article from Coastal Climate Control about AGM batteries.
http://coastalclimatecontrol.com/index.php/blog/192-a-true-balancing-act.html
You might find it interesting as well.

Since I also cooked my batteries last week, I am about to call them and ask if these Battery Balancers would help flooded batteries as well.

Eventually one day I will add solar, just not convinced yet.

Sincerely, Alexandre

Re: [Amel Yacht Owners] Charging AGM batteries

ya_fohi
 

Alexandra,

That is indeed something which should also be checked, but the overheating happened when the boat was out of the water so I do not think it was the cause.

Another possibility is the solar panels. I'm not sure what kind of regulators they have.

Cheers,
Paul

How about the 24 volt alternator on the engine?
What Voltage does it give?
Is it appropriate for AGM batterie?

Because of their internal
construction a full on classic thermal runaway is MUCH less
likely to occur with good agm batteries. Lifeline claims
they have never heard of it happening to their batteries.
You can however, melt them down if the voltage is too high
for too long causing the electrolyte to boil
off. 
Monitoring is
simple. Fully charge, disconnect the charge and load, and
then check voltage after a bit of time to rest. A shorted
cell will quickly pull the voltage for that one battery down
to 10.5. Otherwise, capacity testing and such can be the
same as a flooded battery. 
You'll also see a bad cell in
your charging amps at full charge. They'll never drop
down to the 0.3 amps or so that they should at the correct
float voltage when the batteries are full.

Re: [Amel Yacht Owners] Charging AGM batteries

ya_fohi
 

Thanks for the replies. It seems that the float level of 13.6v is the general consensus. My chargers, Dolphin, which came with the boat, do not have a specific AGM setting. The nearest one is for "sealed lead" which gives 13.6v float but only 14.2v maximum whereas the West Marine website says that AGMs should take 14.7v max. So I guess I'll go with that unless someone advises otherwise.
Cheers,
Paul

Lifeline recommends a float voltage setting of 26.6v for their AGM batteries. They can stay indefinitely at that voltage. Higher voltages will cook them--sooner or later. 

If yours are a different brand, check with the manufacturer.

My Santorin has a Perkins Prima 50. It was 19 years old when I bought the boat with 3,900 hours. It now has around 4,600 hrs.
It always starts first turn of the starter motor, never had to use the pre-heaters. The handbook states oil changes at 400 hours, but I generally change between 100 and 200 at the most. I use below 1 litre of oil to top up between services. I am no mechanic but have faith that this engine will still be working well at 10,000 hours.
 
Check the service history and especially the timing belt replacement.
