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.

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

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)

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

Re: Engine Repower for Super Maramu

Davi Rozgonyi
 

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....

Hi Kent, when you run the manual furling line do you cross it after it leaves the pulley on the forestay. If not you are losing a big part if the rope/ pulley contact friction.

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.

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.

My TMD22 has a Garrett 466770-0006S turbo on it.  I purchased a new “cartridge”  (compressor/turbine and bearing block) for $300.  I’m waiting for the gaskets to arrive from Volvo, so I can’t tell you if it’s a success or not.  I could not find a complete “rebuild kit” on line anywhere. Feel free to contact me if you would like more supplier details on the cartridge supplier. They are in North Hollywood California.

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

Hi Dan,

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.

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

Re: [Amel Yacht Owners] Re: Sludge in fuel tank

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.

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.

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.

Hi Miles,

We had a problem that sounds similar and yet different from yours -- a vibration above 2000 rpm that got worse with higher revs.  I suspected the engine alignment, and was proven right as soon as we had a mechanic look at in in Le Marin.  He replaced the engine mounts, C drive mounts, and Vetus coupling rubber bits.  It's smoother than ever now.  I was very happy with his work.  The mechanic's name is Didier, and his number is +596 696 81 57 22.

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

Re: Toe pulley (headsail)

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%).

Re: Sludge in fuel tank

If the only thing in there is "sticky sludge" that adheres to the walls of the tank, then it is important, but not probably not urgent.  

If there is a significant amount of water, or other liquid that is NOT fuel then you have an issue both important AND urgent.

I am not sure of the piping on the 54, but on a SM you can extend a small diameter hose straight down the diesel fill pipe, and use a hand pump or vacuum oil extractor to get a sample from the very bottom of the tank.  If that is clean, you are (most likely) safe for now.  If you get a sample that contains water, or anything other than clear fuel, you'll need to get as much of it out as you can.

The easiest way to do it is to hire a tank cleaning specialist to do the dirty work.  They are available in most places with a high concentration of large boats, and are usually mobile services mounted on a boat. Short of that resource, I have used a manual oil change pump to suck fuel from the bottom of a tank, put it through a good, clean, water separating filter funnel, and put it back. Keep doing it until no more water or "sludge" comes out.

Have lots of primary fuel elements handy, and monitor them closely until you can get the tank professionally cleaned.

My old boat got its first real tank cleaning as it approached the ripe old age of 40, so if you keep clean fuel going in, you'll get clean fuel out for a long time!

Hi all,

Out Amel 54 is 10 years old, and the fuel tank has never been cleaned. I noticed today from the dip stick gauge that there is a coating of sticky sludge at the bottom off the tank. I have no prior experience of treating this, and am reluctant to try while we are on a mooring buoy. I would appreciate ny advice on a) if this should be addressed urgently and b) how best to do it.

Cheers,

Re: Head sail furling

Kent,

I hope this doesn't show as a duplicate message, I thought I had responded, but no message has appeared...

Before you condemn the internal gearing of the furler gearbox, be sure that the drive pin is engaging in the drive plate.  A number of people have reported having the hole enlarge and roundoff, which drives the pin out of engagement.  That matches the symptoms you are seeing.  We have had that drive plate fracture and totally fail.  

I have just had our jib furler gearbox completely disassembled for normal maintenance of seals and bearings.  It seems very unlikely that the gearing would cause the issues you describe.  Mind you "unlikely" is not impossible!

We have twice had to use our manual furling system, and never had any trouble with it.  Our furling  line is standard 10mm double braid polyester line.  I wonder if the StaySet is just a little too stiff?  I am sure that 7/16" line would not be too large for the drum.

Locally, the go-to guys for Amel rigging are Nance and Underwood in Fort Lauderdale.  If you needed a new drive plate made, they can do it for sure.  Roger Underwood is the guy to get in touch with.
