More than likely your problem is the crankshaft bearings and the connecting rod bearings clearances are too large. As the engine warms the expansion of components causes the clearances to increase even more and hence the oil pressure to go down.

 

The prognosis for this situation is not good. Sorry to be the bearer of bad news…

Hi there James

 

Starting oïl pressure (cold engine) reads now 3 bars with 1300 rpm (goes up soon as engine starts - no time lag, good sign that pump is working)

goes down to 2.8 bars when warming up to 70°C

 

idling at 700 rpm when warm at 70°C drops down to 1 bar - sets on the warning beeper

changed setting on engine to run idling at 850 rpm - oïl pressure goes up to 1.2 bars (no more warning beeper - a rest for our ears)

 

when accelerating to 1500 rpm oïl pressure runs up to 3.2 - again immediate, no time lag)

 

oïl pressure gauge is reading; was on zero when first started & cooling hoses were inverted. Went up to reading when corrected. No clue on correctness of reading as no calibration done.

 

However did the good old check on oïl pressure to unscrew the oïl filter & got a good shower, followed by unscreing the pressure gauge & watching the closest I know to a Blow-out on an oïl rig.

 

I did not find a replacement oïl pump for the engine & fitted the 'old scored' one back in; still looking & searching now with oïl pumps manufacturers as I have seen similar designs, but different sizes on the net. Intent is to find one to be available by early 2020 latest to allow for dismantling of engine (again) & refitting a new or reconditionend pump.

 

Guess I will try & stretch the life of my 4.154 to get some retunr on Investment for the repairs done here in Tenerife.

will do an update when returning to home port in 2019

Just to complete results of trial run, oïl pressure went down to 1 bar at 700 rpm after 3 hrs running (cooling maintained at 70°C).

Engine purring nicely, no leaks.

I book it to the ol pump condition (scored  innards).

Added Wynn's Supercharge to thicken oïl & oïl pressure went up to 1.2 bar at 700 Rpm; much better but temporary solution.

Thinking of adding one oïl pump piggy-back on engine (oïl cooling hoses) either driven by pulley or electric. Will pursue.

Hey Eric- I've been toying around with the idea of repurposing the life-raft locker in this way. One non-scientific data point that has given me pause is that when I last changed batteries, I had all 13 DT-31 batteries on the port side of my boat outside the cockpit waiting to be taken off. I noticed (or at least I perceived) a slight list of my boat to port. I wondered if 300 liters of fuel in the locker would create a similar issue. Have you noticed this ? Confession- I've done no calculations relating to the relative weights, the position of those weights, etc............one of those possible boat projects that sits idling in front of the first speed bump it encounters.

Re: [Amel Yacht Owners] Re: Auxiliary fuel tanks

greatketch@...
 


Tom,

300 liters of diesel would weigh about 640 lbs, Thirteen G31 batteries at about 75 lbs per would weigh between 900 and 1000 lbs.

Just another data point for you as you decide what to do...

I get the distinct impression I am a minority on this, but I personally would skip this project--unless you motor a lot. A Super Maramu has a range with the installed tanks of about 1000 miles.  Much more twice than my previous boat and I never felt the need for more fuel in that one.  I don't think I have ever motor-sailed our Amel, but others seem to do this quite a bit. We cruise full time, and buy fuel about four times a year.  For us, cutting out one fuel stop every 12 months just doesn't come close to justifying the project.

The liferaft locker does double duty on our boat, holding the raft and other things. I would need to make space in other places for them, and it's not worth it to me.  Also, we have the older boat with only 9 batteries, so we start out with a list to port from the weight of the generator on that side. I consider that list important, but maybe that's because I would rather sail in 4 or 5 knots of wind than listen to the motor...

Miles,

   If you have not yet done so, check to be sure that the drag is all of the way off on the wheel.  I think that I read a while back that the steering cables are sealed but get someone to verify this.  The rudder,  hull and skeg clearances are tight so a bit of growth could also certainly stiffen things up.    

Best of luck,

I had wondered about that welded ring. My boat has been re engined but I guess this is to stop running the engine and prop shaft alternator together! Smart.

Re: [Amel Yacht Owners] Re: Hurth Transmissions freewheeling folding prop

Correct. Leave engine in neutral. Your keys should be on a welded ring. Take keys from ignition and switch on prop alternator key. Green light should show charging. To stop turn off and extract key. Green light may still show charging. Stop by putting gears into reverse. Into neutral and start engine.
Don’t know what size your alternator is. Mine is a 50amp. It only puts a couple of amps in until I’m over 5 knots then it starts producing. Crossed the Atlantic with batteries at 100% all the way - all on the prop alternator.
Have fun.

Hello
I have yet to test out my maramu prop shaft alternator. I’m hoping to this week though. 
Am I right in assuming I put the gear into neutral to allow the prop to freewheel then switch on the alternator charging ?
Simple as that?
To stop just engage the gear to stop the prop from turning then turn off the alternator?
Many thanks in advance

will order some and give it a try.




 




   So if I understand you correctly,  you changed your aluminum cooler
back in 1997 when the engine had 4,000 hours on it,  you now have 10,000
hours on your engine and you are still using the same cooler?  May I ask
where you ordered your cooler from?  It seems that some people are having
problems with their coolers corroding quickly.




 




   Perhaps our boats were built side by side side since Sueno is #220?  
May I ask where your boat is now?

From 99 to 2006 I was living on board using marinas only when could not be

   That is amazing,  you must be taking exceptional care of your

nice to know which factors seem to lead to a longer service life.

   Thanks for the initial update on your rebuilt Perkins.  The Perkins 4-154 manual that I just checked is showing the normal oil pressure to be between 30-60 PSI or about 2.1- 4.2 bar at “maximum engine speed”.  They do not seem to list an idling oil pressure.   What was the initial oil pressure when the engine was first started and cold?  How is the oil pressure at your normal cruising RPM?  Is there any chance that your oil pressure gauge is not reading correctly?   I am really happy that the engine seems to be running so well for you.   Were you unable to find a replacement oil pump for your engine?

will do an update when returning to home port in 2019
Just to complete results of trial run, oïl pressure went down to 1 bar at 700 rpm after 3 hrs running (cooling maintained at 70°C).
Engine purring nicely, no leaks.
I book it to the ol pump condition (scored  innards).
Added Wynn's Supercharge to thicken oïl & oïl pressure went up to 1.2 bar at 700 Rpm; much better but temporary solution.
Thinking of adding one oïl pump piggy-back on engine (oïl cooling hoses) either driven by pulley or electric. Will pursue.

christian alby,


    Thanks for taking the time to update us on your freshly rebuilt 4-154 along with verifying the cause of the failure.  I hope that the engine provides you many years of good service.  If not too much trouble, could you do another update in 1-2 years on how the engine has held up?

Thanks,

Thanks to all Amel sailors who assisted me find parts for my 1982 Perkins M 4.154.
Engine is rebuilt now with new pistons, liners, bearings ... Including a brand new starter to replace the one burnt by the workshop electrician who tried to run faster by hooking my 'old faithfull' 12 volts starter on 2 batteries in series at 24 Volts !
Engine on board 19/12; hooked up & running same day at 17:00 (lost time on drive end bolts offset by 1/4 turn - lift engine & rotate whell -, then oïl cooler hoses inverted, no return = no oïl on pressure gauge).

the cause of the fault was definetly the diesel lift pump diaphragm; 63 US$ Worth of spare, Worth changing on engines which did not run for over a year or so. Check them often.

Otherwise I can only recommend UK & USA suppliers who responded & supplied replacement parts; And Tenerife workshop 'Precision T.' who did a perfect job on the mechanical part; Just keep electricians away from our installations, not their best show of experience.

We shall sail away on 24/12 to continue our round trip of South Atlantic.

fair winds to all

Re: Auxiliary fuel tanks

Derick Gates
 

Brava's previous owner mounted the life raft on the port stern rail, and installed a 240 Liter aluminum tank in the life raft locker.  This tank is plumbed into the diesel circulation system, allowing it to be used alternatively to the main diesel tank by shutting off the main feed (in the passageway) and the main return line (just before it gets to the main tank) and opening the spare tank return valve (by-passing the main tank return valve) and spare tank feed valve (as it emerges from the spare tank).  

I use the main tank until it is nearly empty, then use the spare tank. Then vice versa after filling the main tank.  I try to use a FIFO approach (First In, First Out) in using the fuel in the two tanks.  As a safety precaution in case of bad diesel, I never fill both tanks at once from the same fuel source.

The extra weight of the full spare tank only adds about a degree of port side list.  I try to counter that with storage of equipment and supplies on the starboard side, but do not obsess about it.

Subject: Re: [Amel Yacht Owners] Hurth Transmissions freewheeling folding prop  Dave,    Thanks for this information.  At least I now know that at least some of the Hurth 250 transmissions installed on Maramu’s are lasting longer than the 4,000 hours that mine has..  So far my transmission seems to be working fine but the failure mode that you experienced does not sound like a pleasant to experience so maybe I will do something preemptive before long.       I have heard of others having a problem with their aluminum coolers corroding quickly as well..  Without being bonded, I would think that the aluminum parts immersed in seawater would become the sacrificial items on the engine so maybe that could be part of your problem as you suspect.  I am wondering however if there is more than one manufacturer of these coolers with some being made of a more corrosion resistant alloy?  The original cooler on my transmission had a plate on it that in large letters had the name Hurth,  Monchen,  Made in West Germany.  The old rusty hose clamps, hoses and the apparent age of the ID plate and mounting bolts suggests to me that this cooler had been on the transmission for a very long time..  The one that I ordered as a replacement and installed this year with all new hoses was sold by “Mr Cool” 3306107001 ZF Transmission/Gear Cooler.  The replacement cooler cost $165.00 USD.  The Cooler being sold by Foley is much more expensive,  $395.00 which comes with a quart of their special synthetic fluid. I think I will inquire and see what they say about the large cost differential.    Can you tell me where you have been buying your coolers?     In part over corrosion concerns for my cooler, I have been flushing the engine with fresh water whenever the engine will sit for more than a couple of days which I think should help to reduce the corrosion some.   I think that I will open the cooler at least every couple of seasons to see how much corrosion is present.   Best, James  AltonSV Sueno,  #220Arbatax,  Italy

Are you satisfied with the marina that you are at in Cartagena?

A year ago we were in the Santa Marta marina. It is a lovely marina. Unfortunately when the wind is from the East the boats get coated in coal dust as there is a coal burning plant to the East of the marina. I was thinking of heading to Colombia again later this year to spend some time with my novia.

I am glad that you are having good luck! Thanks for the tip on the Militec-1, what I have read about the product sounds very promising. I will order some and give it a try.



So if I understand you correctly, you changed your aluminum cooler back in 1997 when the engine had 4,000 hours on it, you now have 10,000 hours on your engine and you are still using the same cooler? May I ask where you ordered your cooler from? It seems that some people are having problems with their coolers corroding quickly.



Perhaps our boats were built side by side side since Sueno is #220? May I ask where your boat is now?

Hi James

- Good care : YES , Exceptional care: I do not think so. The only thing I use , that not everyone use , is: MILITEC-1 (everywhere possible, on sea and on land) according to the producer recommendations . Nothing to do with the cooler.

- Cooler : Yes I have the small square aluminum cooler. I changed it on 97 . when I received the boat, with 4,000 hours.

From 99 to 2006 I was living on board using marinas only when could not be evitable. In the last ten years, at the end of my four months sailing season, in April, I ran the engine for one hour with fresh water(half an hour one day and half an hour, one day or two later) .

A little of luck is always welcome.

Gabriele Anolini,



That is amazing, you must be taking exceptional care of your transmission. Do you have a cooler on your transmission? Foley seems to be saying that 1000 hours is about all that we should expect. It would be nice to know which factors seem to lead to a longer service life.



Happy Holidays,



James

I can confirm you that the Hurth 250 transmission can work much more than 4,000 hours. Mine passed 10,000 hours and , still now, never gave me a problem.

Dave,



Thanks for this information. At least I now know that at least some of the Hurth 250 transmissions installed on Maramu’s are lasting longer than the 4,000 hours that mine has.. So far my transmission seems to be working fine but the failure mode that you experienced does not sound like a pleasant to experience so maybe I will do something preemptive before long.



I have heard of others having a problem with their aluminum coolers corroding quickly as well.. Without being bonded, I would think that the aluminum parts immersed in seawater would become the sacrificial items on the engine so maybe that could be part of your problem as you suspect. I am wondering however if there is more than one manufacturer of these coolers with some being made of a more corrosion resistant alloy? The original cooler on my transmission had a plate on it that in large letters had the name Hurth, Monchen, Made in West Germany. The old rusty hose clamps, hoses and the apparent age of the ID plate and mounting bolts suggests to me that this cooler had been on the transmission for a very long time.. The one that I ordered as a replacement and installed this year with all new hoses was sold by “Mr Cool” 3306107001 ZF Transmission/Gear Cooler. The replacement cooler cost $165.00 USD. The Cooler being sold by Foley is much more expensive, $395.00 which comes with a quart of their special synthetic fluid. I think I will inquire and see what they say about the large cost differential. Can you tell me where you have been buying your coolers?



In part over corrosion concerns for my cooler, I have been flushing the engine with fresh water whenever the engine will sit for more than a couple of days which I think should help to reduce the corrosion some. I think that I will open the cooler at least every couple of seasons to see how much corrosion is present.

James,



Our Hurth 250 started acting up in 2002 with about 6000 hours on the engine. Intermittently it would not go into forward, first discovered when backing out of a slip which made for an interesting evolution. We had it rebuilt with no issue.



Maybe I have a grounding problem on the 4.154 but the aluminum cooler only seems to last a year or two.. I now have several, and try to catch the corrosion before it gets to bad. Then I clean up the cooler and rebuild it with aluminum epoxy that I buy from Cotronics. Works really well.

Mike,



My Maramu has a plate mounted just in front of the shift lever warning to never leave the transmission in Fwd. gear while sailing. My boat has a fixed 20” (?) 3 blade prop which can produce a large amount of torque when sailing at higher speeds. I am guessing that since your prop feathers(so produces little torque if any when feathered) that it may not matter as much which gear you use but apparently due to the design the Reverse gear is stronger and therefore safer to use when locking the prop shaft. Perhaps others can verify if this would be correct.



I also read in Foley the these gears seem to last about 1000 hours on average. The gear on my boat has the same paint as the engine and I don’t see any evidence of it having been replaced. The engine now has just over 4,000 hours. Could others comment on the life expectancy the have experienced with the Hurth gears? My boat appears to have had an aluminum cooler for a very long time, it may in fact have been original based on the installation. I replaced the old cooler with a new aluminum one.. The old one was not leaking but when cleaning out the inside I found several pin holes that were only plugged with corrosion so it was overdue.. I just got an email back from Foley saying that they have discontinued selling the stainless coolers and now only sell the aluminum. I wonder if there were corrosion concerns betwee the aluminum gear case and the stainless coolers. I will try to find out.



Best,



James

Who’d of thought there was so much to know about transmissions and their lubrication! Foley website full of interesting information. On a related topic...



Dr.. Diesel Tip #101 at Foley says DO NOT put Hurth trans into forward to stop freewheeling, only reverse.

We have always put the trans in forward to stop the freewheeling and fold the Autoprop when under sail. Given Amels have a “C” drive, does Dr. Diesels Tip apply? Have to pose the question just in case there are opinions among our ranks.

Hi Tom,

I don’t notice any major list to port with the 70 gallons in the liferaft locker, possibly a degree or two.

Additionally the fuel in the tanks is not a permanent condition as is the batteries.

Hey Eric- I've been toying around with the idea of repurposing the life-raft locker in this way. One non-scientific data point that has given me pause is that when I last changed batteries, I had all 13 DT-31 batteries on the port side of my boat outside the cockpit waiting to be taken off. I noticed (or at least I perceived) a slight list of my boat to port. I wondered if 300 liters of fuel in the locker would create a similar issue. Have you noticed this ? Confession- I've done no calculations relating to the relative weights, the position of those weights, etc............one of those possible boat projects that sits idling in front of the first speed bump it encounters.

I didn’t know it was continued into the earlier SMs. I am quite happy with a bit of drag to get all the amps back in the batteries under sail.
I have about the same engine hours as you.

Ian,
  Some early SMs also have the shaft alternator.  I have used it extensively for the last year.  The previous owner sailed around the world with trans in neutral to make use of the alternator.  So far with 4500 hrs on engine and trans we are running fine.
Also have fixed blade prop. Hurth Z25 trans and TAMD22.

There are some Maramus and Santorins out there that benefit greatly from the prop shaft alternator. The only time I engage reverse with the engine off is to ensure the prop shaft alternator is off prior to startup of the engine. I only engage forward when the engine is on and I want to go forward.
