My first bow thruster service...

greatketch@...
 

First thruster service and everything is going fine--much better than the "typical" boat project! Thanks to a great design, and great maintenance from the previous owner.   But I have a few detailed questions for the experienced Amel folks.


First, the lip seal on the retracting shaft.  It is a standard Type 35, rubber coated 60x80, single lip seal.  EXCEPT: the new seal I received from AMEL, and the old one that was previously installed, have had the lip spring removed.  I can see it was removed from the new, unused part because the impression of the spring is still on the inside of the rubber lip.  I am working on the assumption that this is by design and for some reason in this application the spring is not desirable. Correct?


Second, the use of RTV on all the joints.  I am used to o-rings and lip seals being more than good enough by themselves--when installed properly.  When covered in RTV, o-rings become essentially single use because cleaning upon disassembly becomes impossible.  Once the RTV hardens, it prevents an o-ring from adjusting itself to small movements of the parts. It is also just messy and hard to keep away from places it shouldn't be. On the lip seals, the rubber coating is designed to "stick" to the wall of the chamber it sits in, and coating it in RTV actually makes it less secure.


The posted procedure in the forum basically has every possible joint (including several that are not actually sealing surfaces...) being slathered in RTV during assembly.  My 20 year old instructions on bow thruster repair from AMEL do not mention this.  Have people found this to be an important addition to the sealing of the thruster assembly?  Or do some people do it because "it can't hurt"?


If it is important, I'll do it.  But left to my own devices I'd skip it and let the seals work as they were designed.

Bow Thruster Jack Screw on 54

hodginsbob@...
 

I need some help with the wiring circuit for the jack screw that drives the bow thruster up and down. I understand that the set up of the thruster on the 54 is very different that all previous models? I can hot wire 24 VDC to the jack screw motor and make it move up and down. The challenge is in the circuit that is supposed to control the motion and the lights and buzzers at the helm. The circuit has 2 limit switches and 4 relays forward, and the switches and lights at the helm. On Gallivant, I am not the original owner, and there appears to of been multiple attempts by semi knowledgable mechanics (one of them me) at fixing it, so at this point I don't know how it was built originally. The wiring diagram supplied in the Amel manual is not detailed. It does not show indicate when a relay is activated if it opens or closes a circuit, and there are no wire colors marked. Has anyone sorted this out and is there a good schematic? Does anyone know the specifics on the relay that I can buy a complete set? How about a source for those tiny fragile limit switches?

Good evening (?) everyone. I need to add a fourth battery to the service group. The DCC400 is now rated at 300A. To set the CAP parameter to 400 is enough?  Or  other changes are needed?
Thanks for your reply.

Ben , We love Les Saintes , probably our favorite place in the Caribbean . The town is safe and an interesting place to hike about , plenty of places to eat. Years ago there was plenty of places to  anchor , now they have placed mooring everywhere , can't remember ,but prices weren't bad. You need to arrive by  early afternoon on weekends to get a mooring . New Years Eve is a blast ! If you leave the town astern and go around the first point to port you will see boats anchored there , with snorkeling all around there , consult a dive book for locations.
Wish we were there,

Hi Ben and Gayle,


 You will enjoy the Saintes. We anchored happily off Bourg, the main settlement ( whose only hazard is a  wonderful dress shop shop with  Caribbean coloured dresses, so, Ben,  hide your credit card from Gayle).  We also anchored on the W side of Ilet a Cabrit and Anse a Cointre.


 Good walks ashore. Do go up the hill to the N of Bourg to visit Fort Napoleon.  When we were there ( 2009) the fort contained three large glass topped tables with models of 18th century men of war. Being then ignorant of my naval history I saw from the first table that the English and French fleets were lined up in opposition; the second showed the English doing rather well; the third showed the French fleet routed or sunk.

 It was the battle of the Saintes, 1782, the great victory of Lord Rodney ( he of Rodney Bay in St Lucia ) and it secured the West Indies for England for a very long time.


I told the concierge that I thought it very generous of the French to display this battle, which must be a cruel memory for them. His answer 


 " Francais ? Nous ne sommes pas  francais! Nous sommes de Bretagne ! "    I then learnt how the Bretons had settled les Saintes, not the French.  Three centuries later they were not about to let anyone forget it.  As anyone visiting Brittany today will know , they still pride themselves as being Celts and rather separate from the rest of France.



 Have fun.


 Ian and Judy, Pen Azen ( named after a rock in Brittany which has huge tides. Nearly 40 years ago in our first, 27 ft boat, we misread guiding lights at 0200 and sailed innocently over a rock called Pen Azen. Only the next day did we see from the chart that at low water the rock dries 28 feet!   by chance we had sailed over at the top of a spring tide--which rises 35 feet.   Pen is a Celtic word menaing Head and Azen is old French for donkey ( think asinine). The rock has a profile of a donkey's head at low water. We were certainly donkeys on that night and we decided to pay homage to Neptune by calling subsequent boats Pen Azen. Our SM is  the fifth by that name. So far, Neptune has repaid our respect )

from experience on our Maramu, opening up all ( tank top hatches to Survey the gelcoat coating condition & the earth plate,
the only tank which can easily overflow, once all hatches have been securely bolted & seals properly greased & inspected in position, is the aft tank, Under the sink; easy to access even though tricky to inspect (Mirror or camera needed).
4 openings up top to let pipes through (filling, float, foot pump & electric water pump); however all are well above the high level of water.

check also for obstructions on all tanks (forward of #2) give free access to water when filling up (2 holes between each compartment, bottom of tanks). the float measures height of water in tank #1 only.

then last resort is to check if leak does not come from faulty connection on copper tubing feeding cold & hot water from pressure bottle, as the tubing is fed through from the engine compartment to location Under the fridge & in time tends to break at the elbow (not easy to reach as this is covered in resin to support tubing, and located Under the pumps shelf in the engine compartment).

Graham,

   So far thankfully no event as you have described.

   Just a guess of course, but I wonder if one of the access panels or (something else) on the tanks is leaking and you were filling above the top level of the tank into the bilges?   The tank fill is quite a bit higher than the tank top and fittings so it could be anything in the system I think.   It was quite easy on our Maramu to remove a few fasteners and move the big table off to the side which gives access to the tank access ports.  Maybe open up access to the whole top of the tank and try again to top up the tank to find what might be leaking.  

Best of luck and report what you find.

Graham,
I've overfilled my tanks (SM, not Maramu) with the same results.  Recently I'm finding fresh water in the bilge when the tank gauge is reading only a little over 900 L (1000L Capacity on SM's).  I've checked the inspection ports in the aft two tanks and they are sealed as best I can tell.  I've still not been able to access the forward tank.
So far I haven't found the cause, but wonder if the float on the gauge could be riding lower than it should.

Re: [Amel Yacht Owners] Rudder dismantle

James, yes we did. The crack looks deep and suspicious and in a  position very difficult to inspect. 
Unfortunately we have a very poor connection and can't then post pictures today. 
We have finished to prepare the work and tomorrow should unload the rudder. 
Will also check the nylon (or teflon ? ) bushing inside the central support of the rudder (femelot) but guess not expected to be changed (unless made in two parts ?). 

Thanks again to Christian for his very detailed step-by-step  suggestions.

  The rudder is made of two halves so some evidence of a seam may be normal.  Again the Amel rudder is new to me so if an expert like Oliver responds I would be listening to him.  
   Have you tried applying moderate force to turn the rudder each way (perhaps two men pushing on the rudder TE while the rudder shaft is held in some fashion) to see if what you think is a crack opens and closes as the force is applied and released?

Deep cycle batteries used in UPS and telecommunication applications are rated in reserve capacity, which is the number of minutes the battery will maintain a constant 25A load at 80 degs. F until voltage drops to 1.75 volts per cell. To provide an approximate conversion to amp-hours, multiply reserve capacity by 0.6.

Bill,

Unfortunately there is no model# on the xantrex.

The settings run 1 thru 20.

I looked at your explanation in the files section as Mark had suggested, and it's obviously not a link 10.

Amphrs...for my 12 pack 600ah I believe.

max volts....you said 26.4 on your explanation, I was thinking 26.7.

current charged parameter....2%

charged parameter time 4minutes

under voltage alarm....22volts

over voltage alarm....if I followed your 26.4 max volts, 26.5, if I followed mine, 26.8

peukert....I'd leave as default, 1.25

most of the other settings appear to warrant a default setting as per the manual

 

What would you consider to be a reasonable amperage to consider shutting off your charger. Obviously, there is a law of diminishing returns here.

A well respected friend, another Amelian, recommended a shutoff when the pack is down 80ah. This would only be a scenario where the gen set is powering the charger. Obviously a full charge would be attempted with shoreside power.

Good Morning Amelians,

I just replaced my battery bank (12), and want to reset the xantrex monitoring system. I am charging the battery bank for the first time after some moderate discharging (130ah).

BTW, after the advise offered by Bill, I believe, I went with standard wet cells, $115 per, no tax.

Using the 30amp charger, I'm expecting to reach float stage at some point. I am showing (on the xantrex) +26a, and in 15 minutes (I've been charging for about 2 hrs) 33 ah, a difference of +5ah in 15 minutes. If I'm interpreting the data correctly, I take that to mean the charger has inputed 5ah of charge into the battery pack. When the battery pack reaches approximately 98% of it's charged capacity, I would assume the charger will be in float stage. Will the charger recognize this, and alter the incoming amperage current (and show up as a much smaller value on the xantrex, ie say from current +26a to say +2a?

I ask now because I don't want to overcharge the battery pack right off the bat. 

As far as setting the xantrex itself:

f01 600ah

f02 When the pack was orininally installed, the voltage reading was 27.2v. , so I assume 27.1 is reasonable

f03-f06 default

f07 I thought 22v would be about as low as I'd be comfortable with

f08 Considering the original voltage, I would think 27.3 would work

f09-f12 default

f13 I thought the 12 minute figure would be more appropriate considering our usage variences.

f14-f20 default

 

I prefer to shut off the battery power to the boat when not in use rather then run a small independent trickle charger into the pack. I usually leave a note indicating the voltage when I leave, and check it upon arrival to note the difference. Obvioiusly, as they get older, the voltage difference is generally greater, time away being equal.

Any insights into the process, or observations regarding my settings plans, or if I am misunderstanding the data/process, please feel free to comment.

Hi Bill,
Yes, I understood that.  After buying batteries with a much different profile than the others I've had (by mistake, as they were called hybrid marine batteries, just like the old ones), I was charging them wrong and getting poor performance from them.  I was hoping to add something that would encourage him to learn a bit more about his batteries and charging them to get maximum performance and longevity.  I'm obviously still learning about this, too, and my last battery purchase was poorly done.

Jeffrey,

As a general rule, when you are using the Onan, use the 100 amp. With shore power use the 30 amp. The only time you are concerned with shutting off the charger is when using the Onan.

I hope this helps you.

right on with those values,
As far as the charging goes, I observed the amperage in, and 30 would be too high, perhaps you're using the 100 amp charger to get that value. That would seem to be appropriate. I'm figuring 18 would probably be appropriate with the 30 amp charger. I like the idea of watching amps in as a judgement of when to stop charging rather then the amphr value.

Jeff,

Rather than looking at remaining Ah or %, I like to look at the number of amps going into the battery. I shut off charging when the number of amps going into the battery is less than 30.

The write-up in the files section that I posted there is for a Link10. You probably know that Xantrex bought Link, and made the last production of Link10. If you have a round face, you have a Link 10 and if you have a square face, you have a Xantrex Battery Monitor. I think that you have the latter...if so,:
F1 = battery amp hours times 12 then divided by 2. if they are 100 each then 600 is correct
F2 = 26.4
F3 = 2.0%
F4 = 4 min
F5 = (Default is 50%...I would use 65%)
F6 = 80%
F7 = 24.0 or possibly 23.5
F8 = 29.5
F9 = AU
F10 = 1.25
Remainder of the settings should be at Default Values

I believe Jeff is talking about the Xantrex battery monitor which has nothing to do with the charger and is not connected to the charger.

There are battery monitors which do actually control the charger, but what Jeff has is simply a monitor.

Jeff,

You need to know the recommended bulk amperage, top-up voltage (sorry, my mind has gone blank for the proper term for the high voltage necessary to charge between bulk and maintenance charging), and the voltage for maintenance after full charge is received for your batteries to set you charger appropriately.  I had to call the battery manufacturer technical support people to get this information.

My AHr and % charge readings get progressively less accurate with each charging cycle.  Like others say, use the battery voltage to tell you when to charge (I charge when it is 24.7V or more).  Use the Amps going into the batteries to tell you when to shut the charger off.  I have a 400 AHr bank and charge until it reaches 10A...Usually 1-1 1/2 hrs twice a day (no solar or w ind, yet).  I will go with a larger AHr bank next battery purchase.

If you are only charging to 30A every time, you will need to activate an equalization (desulfation) cycle every 2-4 weeks to refresh your batteries, or they will not hold a charge as well.

Jeff,

You need to know the recommended bulk amperage, top-up voltage (sorry, my mind has gone blank for the proper term for the high voltage necessary to charge between bulk and maintenance charging), and the voltage for maintenance after full charge is received for your batteries to set you charger appropriately.  I had to call the battery manufacturer technical support people to get this information.

My AHr and % charge readings get progressively less accurate with each charging cycle.  Like others say, use the battery voltage to tell you when to charge (I charge when it is 24.7V or more).  Use the Amps going into the batteries to tell you when to shut the charger off.  I have a 400 AHr bank and charge until it reaches 10A...Usually 1-1 1/2 hrs twice a day (no solar or wind, yet).  I will go with a larger AHr bank next battery purchase.

If you are only charging to 30A every time, you will need to activate an equalization (desulfation) cycle every 2-4 weeks to refresh your batteries, or they will not hold a charge as well.

Jeff,
I think the important thing is to have the right setting for the charger.
If you did not change the type of batteries your charger (Dolphin? later Mastervolt)should be right.
The xantrex is only a monitor.

Jeff,

Rather than looking at remaining Ah or %, I like to look at the number of amps going into the battery. I shut off charging when the number of amps going into the battery is less than 30.

The write-up in the files section that I posted there is for a Link10. You probably know that Xantrex bought Link, and made the last production of Link10. If you have a round face, you have a Link 10 and if you have a square face, you have a Xantrex Battery Monitor. I think that you have the latter...if so,:
F1 = battery amp hours times 12 then divided by 2. if they are 100 each then 600 is correct
F2 = 26.4
F3 = 2.0%
F4 = 4 min
F5 = (Default is 50%...I would use 65%)
F6 = 80%
F7 = 24.0 or possibly 23.5
F8 = 29.5
F9 = AU
F10 = 1.25
Remainder of the settings should be at Default Values

I hope this helps you.

Bill,
Unfortunately there is no model# on the xantrex.
The settings run 1 thru 20.
I looked at your explanation in the files section as Mark had suggested, and it's obviously not a link 10.
Amphrs...for my 12 pack 600ah I believe.
max volts....you said 26.4 on your explanation, I was thinking 26.7.
current charged parameter....2%
charged parameter time 4minutes
under voltage alarm....22volts
over voltage alarm....if I followed your 26.4 max volts, 26.5, if I followed mine, 26.8
peukert....I'd leave as default, 1.25
most of the other settings appear to warrant a default setting as per the manual

What would you consider to be a reasonable amperage to consider shutting off your charger. Obviously, there is a law of diminishing returns here.
A well respected friend, another Amelian, recommended a shutoff when the pack is down 80ah. This would only be a scenario where the gen set is powering the charger. Obviously a full charge would be attempted with shoreside power.

Jeff,


Before we can help we either need to know what model Xantrex charger you have, or a guide as to what those various settings are.

Good Morning Amelians,

I just replaced my battery bank (12), and want to reset the xantrex monitoring system. I am charging the battery bank for the first time after some moderate discharging (130ah).

BTW, after the advise offered by Bill, I believe, I went with standard wet cells, $115 per, no tax.

Using the 30amp charger, I'm expecting to reach float stage at some point. I am showing (on the xantrex) +26a, and in 15 minutes (I've been charging for about 2 hrs) 33 ah, a difference of +5ah in 15 minutes. If I'm interpreting the data correctly, I take that to mean the charger has inputed 5ah of charge into the battery pack. When the battery pack reaches approximately 98% of it's charged capacity, I would assume the charger will be in float stage. Will the charger recognize this, and alter the incoming amperage current (and show up as a much smaller value on the xantrex, ie say from current +26a to say +2a?

I ask now because I don't want to overcharge the battery pack right off the bat. 

As far as setting the xantrex itself:

f01 600ah

f02 When the pack was orininally installed, the voltage reading was 27.2v. , so I assume 27.1 is reasonable

f03-f06 default

f07 I thought 22v would be about as low as I'd be comfortable with

f08 Considering the original voltage, I would think 27.3 would work

f09-f12 default

f13 I thought the 12 minute figure would be more appropriate considering our usage variences.

f14-f20 default


I prefer to shut off the battery power to the boat when not in use rather then run a small independent trickle charger into the pack. I usually leave a note indicating the voltage when I leave, and check it upon arrival to note the difference. Obvioiusly, as they get older, the voltage difference is generally greater, time away being equal.
Any insights into the process, or observations regarding my settings plans, or if I am misunderstanding the data/process, please feel free to comment.
Fair Winds, Sunshine, and Best Wishes to All!
