Hi Andrew,
I use parts4engines. They are helpful and have a useful website. Some older Volvo parts are identical to Perkins parts and much cheaper.

Subject: [AmelYachtOwners] Volvo Penta MD21A - Lift pump kit and radiator cap

Hi all,

Spoken to a number of Volvo dealers here in Greece and the UK and the two above parts are obsolete. So in Volvo terms, 'we no longer sell a simple radiator cap, simply replace the engine instead'.

OK so being slightly funny here but this is the issue.

I can send a picture but on Ebay this is classed as a vintage radiator cap which at 40+ years old I agree with, however can anyone recommend places to get a simple service kit for a lift pump and more importantly this radiator cap?

Thanks all

Andrew

Re: Recommended solar panel brand

We've had good experience with SunPower.  We were looking specifically for flexible panels for our bimini because we didn't want to add an arch, so maybe what we found isn't quite applicable to you.  There is a huge variance in the quality and price, as you discovered.  My wife, Kelly, has a background in solar power and did all the research for our installation.  She decided on SunPower E-flex 100W panels which have very high efficiency and low cost (now they're 110W in the same size and price).  We bought them through Sun Powered Yachts.  We've been very happy with the performance -- our 500W of panels meets over 90% of our demand while at anchor (and probably exceeds demand in northern latitudes, but we haven't collected as much data outside the tropics).  Kelly wrote up a detailed article on our installation which was published in January's issue of Sail Magazine.  Unfortunately it's not online yet, so I can't give you a link.

Hi Scott, 
Matt's input sounds familiar to me and it is worth to touch each and every cable inside and around the Sleipner BT.

I had a similar experience few month ago where the BT sometimes worked and sometimes not. I measured all cables with the Volt Meter and all the circuits showed me the Voltage as expected in working order. I was close to give up after tested all Voltages, also the BT-Motor including the brushes looked good. Then I started (with the Ohm-Meter) to measure  the residences on the cables which should be very low with that sizes of cables. I found a short cable who had a bit higher resistant.

But the connections looked good because the cable and cable-ring terminals where put together with shrink-tubes. I disconnected the cable and pulled on it and the ring-terminal came off. The result you can find on the pictures attached. The cable looked like welded OFF¨! New cables solved the problem.

Re: A54 bow thruster directly to battery or through main switches?

 

Scott, 

I am very sure you've checked this, but it sounds like an intermittent break in the low amp control circuit, and probably the low position sensor (analog or newer sensor) and/corresponding relay(s).  

Another 54 owner experienced exactly this problem. He found the low position normally closed analog push botton to be defective. Yet another had the same problem and found 1 of the 4 relays to be faulty. 

I think you can test the control side of the motor's high amp solenoid switch for control-side loss of power this way: Lower the BT. Disconnect the large red positive wire. Hold the joystick to either side while checking amps on the control side of the large solenoid. Hold the switch long enough to have experienced a shutdown based on previous experience. If necessary, repeat in the other joystick direction. I believe that the above will tell you if it is the motor or the control circuit.

Good luck!

Borrow several voltmeters. Attach them to the BT wiring at a few places along the wiring path. Run the BT to failure, check each voltmeter for voltage. Thus will help you locate the problem. Its likely a thermal open failure. Some termination, when cool, transfers current. Its got a resistive problem (maybe a corroded or loose ring terminal?). It heats as the BT operates. When it gets warm enough, mechanical movement causes an open, and it stops. When it cools, the process starts again. Also, it possible that after the BT stops, to quickly lay hands (or use an IR thermometer) to check for a hot termination somewhere along the wiring path. That would be your suspect problem location.

    That is a strange one.  I would try measuring the voltage at the motor during operation to what is going on.  If you lose power at the BT during your test then back track the BT wiring  while operating the BT to find the fault.  If you have voltage at the motor when it stops during your test then look into the motor.  Maybe a relay issue?   Best of luck.

Our bow thruster was indeed wired through a switch, too.

I've worked with Sleipner to try to isolate the intermittent functioning problem to no avail. It runs full speed and then stops momentarily and then will start again. No slowdown to indicate drop in voltage. The Amel joystick has been cleaned and tested and shows nearly zero ohms on activation.

Every switch and thermal protection within the Sidepower thruster has been "jumpered" and it still doesn't work. I was hoping the problem was the main battery switch but I moved the positive bow thruster supply wire from the secondary side of the switch directly to the battery side. The only thing left is the motor itself but the brushes and commutator look perfect. The annoying bit is that this motor is only a year old and Sleipner wants me to ship it back to them from Panama at my cost, wait for them to test it, get warranty approval, ship it back (at my cost) and pay customs duty. I might as well buy a new motor! With a canal appointment, I clearly don't want to do this.

Anyone have any other ideas on what I should check? I haven't tested voltage at the BT during operation because I don't have alligator clips, but the fact that the BT either runs full speed or not at all, without any slowdown indicates to me that it's not an issue with enough voltage getting to the BT.

I would like to point out to everyone that this is really admirable on the part of Amel. When I contacted the US branch of the company that originally made these racks, there was not any desire on their part to make these discontinued racks available. I am not sure if Amel convinced them, or found someone else to make the racks, but in either case, Amel used their expertise and leverage to support owners with a discontinued manufacturer's part that Amel has not used since the last 54 was produced. Among boat builders, I believe this is remarkable. I know that Maud and Thierry were very supportive of all of us.

Hi,

so finally my BT is back in again (SN). I had the impression that it has never had a overhaul since 25 years. But... amazingly all gears and bearings are still in excellent condition except the seals which were basically gone.
However, after everything was assembled again and connected to the motor, it worked perfectly up n down and more powerful left n right (with oil and not honey in the BT) but unfortunately after some tests the gear from the motor disconnected from the BT. Meaning Motor is turning but BT is dead. all screws are in and tight... I didnt have time to furthet investigate and will ne gone for a while now thinking about it...🧐
Anyone with the same experience or ideas?!

Re: [Amel Yacht Owners] 2nd Forestay on Super Maramu

Danny and Yvonne SIMMS
 

Hi Steve and Alan,

we dont have the inner forestay so fly the 90% off the main stay. I have tried a barber hauler system to sheet it inboard. Not worth the effort so we just sheet it to the outer track. Works fine. Sir Peter Blake, a renowned NZ off shore and round the world racer advised to always sail with slightly cracked (eased) sheets going to windward off shore. Gave a better overall outcome he maintained. Henri must have been of the same persuasion.

In rough weather it can reduce pounding significantly. Important if you want your boat to last.

Hi Steve,

We actually have an inner forestay with a staysail on it, and the problem you would have, as we do, is that in trying to sheet it in, the leech fouls the forward lower stay.

We do actually fly it inside the stay but furled in so it doesn't foul the stay, in heavy weather going to windward.

I doubt very much you would be able to sheet a 90% genoa on the main forestay without furling it to clear that forward lower.

   If you are reading on the H2Out site under the section titled maintenance instructions,  read the last paragraph where they state the annual change out frequency.    I suspect that the change out frequency will depend on a lot of different factors.   Yes, it looks a little pricey to me too,  there could be a better solution.

All good points, James.
Working with dessicant dryers for air compressors, on a humid day, the crystals were pink (from clear) in a few hours. 

I fear that a proper dryer that one could set and forget for 6 months, if it exists, would be active, powered, and be another,complex system to maintain and monitor. Maybe a pressurized system like the ones on automobiles would work, that don’t allow air, readily into the system? I’ve not studied how they work, so I plead ignorance....😊

  I agree.    The desiccant cartridges would need to be replaced from time to time  Most of the ones I have considered change colour indicating the need while others can be heated to drive off the moisture and returned to service.  I have been looking at some commercial solutions so the cost is fairly reasonable but more research is needed to determine the effectiveness and life expectancy in a marine environment.   If anyone has found a good workable solution for installed a desiccant in the vent line please share.

I agree Nick— You're right, certainly about the industry norm.  And I’m sure there are many theories on this: and mine may be incorrect.  But the way I think of it: Crud exists in a myriad of sizes.  Crud forms… then  gets into the filter system and clogs.  If i have a series of sequentially smaller sized filters, i simply clog them all. and then replace them all.  If a bolus of crud makes it into the sequential filtering setup: filters essentially sort the crud into smaller sizes at a great cost (especially with the last Volvo filter now being fouled).  So we've cruised with the 2 micron setup for about 500 hours of motoring from panama to NZ last year and it seemed to work well.  no issues.  Filters seemed pretty good looking when i changed them  Usually around 100 hrs,  (I previously was quite derelict about it, prior to really understanding how important clean fuel was.)  I have noticed the manometer pressure reading on the setup would climb slightly over the 100 hrs, but never concerningly high.  
So scenario above A, with ostensibly clean fuel, worked for us, for this while.
 
 
So… Scenario B: Cruddy fuel shows up.  A slosh of crud makes it into the filter setup. (is this an isolated bit of crud, or does it advertize a yet much larger crub problem in the tank)  Currently it would saturate the 2 micron first filter and pressures climb, engine shuts down alerting us to a pressure scenario  and we change filter: but now we know we have cruddy fuel and need to polish it and the tank. (and why I’d like a separate fuel polishing system on board.)  Heres where my scenario breaks down: it depends on the amount of crud: pump it out and through baja filter into jerry cans? then run engine off jerry cans?  or...( I do have a bunch of 10mn  and 30mn sizes as well) as well put those on and let the filters clean the crud out: but if I increase the racor size then ill be clogging my 130$ volvo filters very fast: i carry about 4 of those, They're proprietary and hard to get in places.  It turns into a "S" show.  
 
So what's governed our cruising: sail smart, with wind as much as possible so we motor little.  Praise our relatively large 900 litre tank, and the freedom it adds to be discriminate about fuel choice. When others are fueling out of necessity, i find myself adding fuel not because i think we're low, but…  hey were sailors and should keep topped up stores.  
 
I'd be surprised if I’d completely thought this through, I'm sure there are some folks who really understand this at a much deeper level and I would love to hear from them and you.
 
And as you note Nick, it is the industry norm, and usually there is good reason for that!  To that end, if the Volvo-proprietary “C” filters were as inexpensive as the racors—I’d also stick to industry norm.  
 
I’d respectfully welcome any thinking and guidance.

Hi Scott and Porter,
 
I choose to use a 10 or even 30 micron filter on the Racor followed by the Volvo secondary filter which is 2 micron I believe.
 
In my opinion by having the pre-filter at 2 micron you are in effect only having one filter. So in the event of major contamination the Racor will plug and the engine will suffer from fuel starvation. You may also damage the fuel pump, although on the 54 the fuel is gravity fed from the tank to the filters.
 
The same principle applies to the water maker. There is a course filter followed by the fine filter. You can not just go straight to the fine.
 
I know this is a controversial subject but that is my opinion….and the industry norm.

I understand. We have the same setup. The dual racor (A vs B) and A+B if one wishes.  We keep the 2 micron on both A and B and use only A or B, switching back and forth.  Filter C is of course the very pricey Volvo-specific filter/fuel water separator, which is what I want to spare by using the 2 micron. I watch the pressure gauge on the racors a lot.  That’s why we change frequently, to keep pressures low.  We have no pre-pre filters.  
 
I remember a thread on this about a year ago, the 2 micron pre-filter argument.  That’s when we switched.  Its hard to be scientific when we have limited data re what works “best.”

Options:

1) FilterA only
2) FilterB only
3) FilterA and FilterB in parallel

Do you run the 2 micron filters here?

On my D3-110C there's a Volvo spin-on filter (2 micron) on the engine itself. We'll call that FilterC

Did you install a pre-filter before the Racors??
