Emergency Furler:
Regarding the emergency genoa furling operation, it should work if you have crossed the leaves to the deck blocks which are used for the "foreguy" for the downwind poles. Of course, the line needs to be tight. If the 3/8” (10mm) StaSet slips in the drum when tight, possibly the StaSet is suffering from the same issue as all of the other lines out there. Most 10mm lines made today will compress to 7mm when pinching with your fingers. This is the primary reason we have switched from 10mm to 12mm for the main outhaul. Take a look at the line on the drum when it is tight. It should be obvious when you see the line go to the bottom of the sheave that the line is too small because of this compression issue. I believe that all rope manufacturers have taken guts out of line in the last 10-20 years and 10mm isn't what it used to be. Unless you are using line with an Anderson Line Tender (no longer made), the emergency genoa furler on a SM, or the genoa traveler adjustment blocks, you probably wouldn't notice that some of the guts of your line was left out by the manufacturer.  It's funny, but unless you own an Amel, you would probably never know that the line manufacturers have taken material out of lines!

SM2k Genoa Furler Gearbox:
A French company owned by a Mr. Vignando’s  made the Genoa furler for Amel. The company is now closed, and Mr. Vignando is retired. But he had several overhaul service kits for SM2000 genoa furler. An Amel School Client recently purchased a service kit  for 750 CHF which converts to 667 Euro or $758USD. The problem is, Mr. Vignando speaks only French, so you should contact him in French language. Mr. Vignando:  a.vignando"at"bluewin.ch, and, of course, a photo will go a long way in translating what you want.

Hi all, Happy 2019!!!
We finally got away from the Chesapeake just before Christmas. Now in Lake Worth to visit friends.

Our jib furler failed to hold while shortening sail in 20kts of wind. The motor turns but sounds like the gears are grinding. After a few turns it gives and the sail unfurls. I just bought a new line for manually furling, 150’ of 3/8” StaSet. It doesn’t hold the sail furled part way, the line slips in the drum.

We managed to get it furled (loosely) completely, by augmenting the manual furling line with short bursts of the motor.

I think the gears are stripped or out of alignment. Does anyone know of a place in Palm Beach or Ft Lauderdale that might be able to do repairs? If not, will 7/16” line hold better on the furling drum until we can get to Amel Caraibes? Any other suggestions or thoughts?
I don’t want to disassemble the gearbox unless I’m pretty sure I can complete repairs before heading out again.

Thanks in advance for any help,

Yes, Danny, the line is crossed after it leaves the drum.  Do I have to keep a lot of pressure on both sides of the line while furling and unfurling?  When single-handing, cranking on one side, tailing on the other side, and tailing the sheet to get a reasonably tight furl leaves me one hand short.  Admittedly, I’ve only tried it a couple of times so I may not have figured out something obvious.  What’s the trick?

Thank you Duane, I’ll let you know what I find...hope that’s the problem!

Kent,


Before you condemn the gearing inside the box, be sure that the drive pin in the furling drum is fully engaging in the drive plate that is mounted on top of the gearbox.  We had our drive plate blow apart a few years ago, and other people have had trouble with the hole rounding over and pushing the pin up.  That sounds like the more likely cause.

Having just had our furling gearbox apart for routine maintenance, I think it very unlikely that the gearing inside the gearbox is the problem.  Certainly possible, but unlikely given what you describe as symptoms.

For the manual furling line, we have 10mm double braid dacron.  That worked great for us on the two occasions we needed it.  I wonder if the StaySet might be too stiff?  7/16" would not be too big.

If you need this unit disassembled and looked at, you might try Nance and Underwood, riggers in Fort Lauderdale.  They know Amel's very well, and Roger Underwood has been a help when we have used him.  If you need a new drive plate, I know they can make one for you.

Hello Miles. Many of us eager to help you suspected you had a 46/48’ Amel Maramu because of your mention of a Perkins M60 and a cutlass bearing. Much of the advice you got was in reference to the later 53’ Super Maramu, much of which is not applicable to your Maramu...
I might gently suggest that all who post here always add the model, year and hull number below your sign off as well as your current exact/specific location.
Why? Knowing what model you have is very important. Sometimes in a given model year ,which runs from September to August the following year, there are not unsubstantial evolutions in standard equipment and configurations. The exact location can often give you the nearby contact information of someone who is Amel familiar who knows how to assist you with your challenge.
Always a good idea to give us all this information to get the best result.

Have fun with your Maramu!

Gentlemen,

 

This thread inspired me to take a look at the condition of the pulleys on my 2004 SM.  Thankfully there are no signs of cracking on either pulley but when I tried to remove them I found at least one fastener on each pulley had "welded" itself to the pulley due to galvanic corrosion.  It took me hours of heating, beating, and gentle coaxing to remove the corroded screws in the controlled environment of my workshop.  And in doing so I caused some minor damage to the threads in one of the pulleys.  I would not want to try doing this on the boat.



Given all that, I'm going to have my machinist make me a new set of these pulleys so I can replace them preemptively in a controlled environment.  I am going to have him replicate the original two-piece design as closely as possible with the raised ribs on each side offset so that the line will "weave" through them.  However, they will be made from 316 Stainless Steel to eliminate the risk of galvanic corrosion between the machine screws and the pulleys.

 

It won't be much trouble to machine a few more sets at the same time so if you are interested in purchasing some, send me an email at mfmcgovern@... (mfmcgovern at gmail dot com).  I won't have a final cost until we've made the first one but I estimate around US$200 per pulley made from 316 Stainless Steel (+/- ~10%).

Miles,

 

I mentioned the engine mounts first because I really think this is going to be the cause.

 

Keep in mind that anything fuel related normally effects the engine regardless of the RPM. However, it is harder to notice fuel deficiency at higher RPMs. It is easier to troubleshoot fuel issue when a load is put on the engine (smoke or lack of power).

 

 

With best regards,

Thanks Mark

 

I’ll check the engine mounts. Looking at the prop shaft when in gear today there does seem to be a slight misalignment by eye. 

I had the cutlass bearing replaced in the canaries so perhaps alignment has been out but somehow got worse via the engine mounts movement etc after prolonged free running of the prop shaft at speed on the long passage. 

There was also LOTS of weed on the passage. A boat we are travelling with seems to have issues with their prop after weed fouling on the trip so perhaps we also were fouled whilst running the prop shaft alternator hard which has exacerbated a prop shaft alignment issue. 

 

Hmmm

 

I’ve bled the system but only up to the injector pump. I am rather ignorant about how air might cause rough running. Perhaps if the air was just in one of the high pressure fuel lines to a single cylinder ? Wonder if this would get worse not better on higher revs. 

 

I’ll also chase the fuel line as you mention to see if there is any obvious signs of problems at unions etc. 

 

The last fuel we took on was in the canaries. Only about 50L. We don’t use much really but that which we did take on in a few places in the canaries always seemed ok and always had lots of throughput at the pumps with all the other boats. I treat with a biocide too but I could have a look at the fuel just in case. 

 

I also have a switchable double canister off engine primary fuel filter. I tried switching that to the new unused filter and the problem remained unchanged. 

 

 

Many thanks again for the helpful thoughts. Very much appreciated

Do you have a good flow of fuel all the way from the tank to the injectors (checking filters, joints for leakage, etc all along the fuel path)

Hi Mark,

I have no problem with biodiesel in my car or boat in Colombia.

However I use a cetane booster additive when I burn Biofuel. Most people say it is not necessary.

 

I also use Howes meaner power cleaner. One bottle is good for 350 gallons.

It eliminates sludge and water from my tank. It is guaranteed to increase fuel efficiency 5% . Most importantly –no more black smudge on the hull, I carry a case on board. I don’t think you can get it ibn Colombia.

Just repowered our 91 SM here in Mallorca...also with a tired Perkins T80. Had some options, including volvo, but after researching the seemingly many expensive problems with volvos (requiring proprietary mechanics/solutions) decided to rebore the Penta and make it like new. Runs beautifully, no mods or worries about matching to the strength of the c-drive or anything else, and simple to fix but hopefully ready for another 26 trouble-free years with any luck....

Kent,

I had the same trouble with the furler not holding a partially furled sail.  My problem was a slightly bent clutch pin (which effectively shortened it) and a pin plate with elongated and ramped holes - I imagine due to those before me ignoring the problem.

I had a new clutch pin fabricated about 2mm longer and that solved the problem.  I had considered reinforcing the pin plate but as long as the pin goes all the way through it wasn't necessary.  There is room for the extra 2mm below the pin plate.

I don’t know about the new yanmar engines. However the older engines like the 4jh4hte in later production was available with an isolated ground. If that option is not available, it is not a terrible problem to make the engine an isolated ground engine. If the option is not available I can walk you through the steps to rewire the engine.

Subject: [Amel Yacht Owners] Engine Repower for Super Maramu

 

 

Happy New Year!

 

This spring I will be repowering Feierabend, our 1992 Super Maramu which currently has a very tired Perkins Prima 80.  I'm in the pacific northwest, and looking at putting in a Yanmar 110hp.  The yard I plan to use has repowered another SM, and are well aware of needing an ungrounded engine.  Their concern is the other Yanmar 110hp they installed was modified to be ungrounded., but not sure if the new Yanmars can be with their electronics.  They have contacted Yanmar to see if this can be done with the new electronic version.

 

This has spurred on a couple questions:

1. I've read through some of the previous conversations, but don't have a good understanding why the Amel requires an ungrounded engine.  With major rewiring and replacing many of the electronics the boat has required, is there a point where it would no longer need an ungrounded engine?

 

2.  There is currently a Kohler 8EoZ generator that is original with the boat.  Is this also ungrounded, or is that not a consideration for the generator?

 

Thanks, Dan

Hi Paul,

Do you use a fuel conditioner in your diesel tank?

Do you have inspection ports that are accessible in the tank?

With a contaminate in the tank I would suggest using a finer racor filter. I believe that a 10 micron is recommended. I have always used a 2 micron.

Bill,

Thanks, that is quite reassuring. The "sludge" is very sticky - I only noticed it when I went to lift the gauge rod up and I could feel it sticking to the bottom of the tank. What I found on the end was some dark brown very sticky residue. I have never had a problem with dirty or watery fuel, so I do believe that what I am seeing is not an urgency. It doesn't strike me as a DIY job though, so as you suggest, next time we're in a reasonably up to date location, we'll call an expert.

Cheers,

Paul

Miles,

If you have a vetus coupling. I think the knocking sound could be caused by the breakdown of the bushings in the coupling. The engine mounts and the C-Drive mounts are  also something to check.

First easy check is the engine mounts. We had your symptoms at certain harmonic rpms.

Standing next to the ending rock it vigorously athwartships. If you can recreate the knocking sound, it is likely one of the mounts.

Hello fellow amelians
In the canaries our engine purred nicely
When we arrived in the Cape Verde’s it was a little rough on idle
On first running since the roughish Atlantic crossing (40-45kts during last 5 days) its even rougher still
I have a Perkins m65 with around 3k hours
It starts on the button but vibrates lots until the revs are increased.
Would be great to hear thoughts on any simple things I could try. I don’t think I can adjust the idle speed on the engine. Perhaps I could via the throttle cable but don’t want to make matters worse.
I’ve bled the fuel

I’m currently in Barbados where I can’t seem to find a diesel mechanic
Next stop Martinique where I’m sure I’ll find good professional
We ran the prop shaft alternator on the long crossing for 2 weeks straight. I started to notice that in the higher winds towards the end of the trip the noise from the rotating prop would change to a less regular sound at speed - almost a knocking sound
I think perhaps the prop shaft alignment needs adjusting. Perhaps the two issues are related although if so I’d imagine the vibrations to get worse with increased revs rather than get better

Any thoughts most appreciated and any pointers to good mechanics in Martinique would be great too

All the very best

Miles

Fuel in Colombia

eric freedman
 

 

Hi Mark,

I have no problem with biodiesel in my car or boat in Colombia.

However I use a cetane booster additive when I burn Biofuel. Most people say it is not necessary.

 

I also use Howes meaner power cleaner. One bottle is good for 350 gallons.

It eliminates sludge and water from my tank. It is guaranteed to increase fuel efficiency 5% . Most importantly –no more black smudge on the hull, I carry a case on board. I don’t think you can get it ibn Colombia.

Eric,

 

I know you have spent some time in the Colombia area and are wise to all things Colombian. We are going to need fuel here and several sailors express concerns due to the bio diesel being the only option. Thoughts?

 

By the way, our boat is filthy. It is not coal but dust. It hasn’t rained since we arrived here and it is very dry and windy. I swear the mountain is being blow away.

 

 

With best regards,

 

Mark

Thanks Mark

I’ll check the engine mounts. Looking at the prop shaft when in gear today there does seem to be a slight misalignment by eye. 
I had the cutlass bearing replaced in the canaries so perhaps alignment has been out but somehow got worse via the engine mounts movement etc after prolonged free running of the prop shaft at speed on the long passage. 
There was also LOTS of weed on the passage. A boat we are travelling with seems to have issues with their prop after weed fouling on the trip so perhaps we also were fouled whilst running the prop shaft alternator hard which has exacerbated a prop shaft alignment issue. 

Hmmm

I’ve bled the system but only up to the injector pump. I am rather ignorant about how air might cause rough running. Perhaps if the air was just in one of the high pressure fuel lines to a single cylinder ? Wonder if this would get worse not better on higher revs. 

I’ll also chase the fuel line as you mention to see if there is any obvious signs of problems at unions etc. 

The last fuel we took on was in the canaries. Only about 50L. We don’t use much really but that which we did take on in a few places in the canaries always seemed ok and always had lots of throughput at the pumps with all the other boats. I treat with a biocide too but I could have a look at the fuel just in case. 

I also have a switchable double canister off engine primary fuel filter. I tried switching that to the new unused filter and the problem remained unchanged. 


Many thanks again for the helpful thoughts. Very much appreciated 

All the best

Miles

Miles,

 

A couple of thoughts:

 

Are the engine mounts in good condition? (asking this based on the issue of noise or knocking sound when running shaft alternator)

Did the problem begin after you last filled up with fuel? If so, you may have bad fuel.

Do you have a good flow of fuel all the way from the tank to the injectors (checking filters, joints for leakage, etc all along the fuel path)

Have you bled the system to eliminate air?

 

 

 

 

With best regards,
