Bill,
One more thing.
I am fairly sure that AutoProp is undersized for that engine. At some point that boat was repowered. An AutoProp H6 would be appropriate for a 110hp engine. I have known other SMs to keep the undersized propeller, but do not know their experience positive or negative.

Here is a letter from Brutons.

Kimberlite Amel Super Maramu #376

 

 

Autoprop Issues Recall   Brunton's Propellers is initiating a product recall, as a precautionary measure, based on customer reports and in-house technical inspection. Their recall letter follows:The recall is necessary because of a small number of instances where, through lack of maintenance or poor assembly, blades on early propellers have become loose. Premature wear to the blade mechanism may, in an exceptional circumstance, result in the blade working loose. Using the Autoprop under such conditions over long periods of time may lead to potential breakdown of the locking washer securing the blade to the hub. This situation will only occur on certain size Autoprops with a serial number between AP2902 and AP5299, purchased between 9/9/98 and 1/1/02.

Please check whether your Autoprop falls within this range. The number appears on the palm of the blade. If it does, contact your local dealer or the autoprop office in England. We can confirm whether your Autoprop is affected or not.

 

As part of our ongoing product development plan, to enhance performance and ease maintenance, a new blade locking mechanism has been introduced. This mechanism is now being fitted to all roller bearing style Autoprops.

 

Brunton's Propellers intends to take the following steps to address this

situation:

 

1. Modification of the bearing retaining and locking mechanism.

2. Free upgrade to new style locking mechanism for all Autoprop user covered under our warranty policy.

3. New generation lip seal fitted free of charge with all upgrades.

4. Worldwide support network of dealers and service agents for local assistance and advice.

 

We appreciate the difficulty in assessing this situation, particularly if your yacht is afloat. If your Autoprop does need technical attention related to this recall, we will endeavour to make arrangements to upgrade it with minimum disruption to your sailing schedule.

 

If you would like further clarification, or to talk about how any of the above points may affect you, please contact our head office on 44(0) 1225 427511, service@..., or your local Autoprop dealer.

William Maffei <william_maffei@...>
 

Olivier,

Thanks so much for this helpful information!!! I will have a better idea what is going on when the boat gets to Malta. Everyone's comments are greatly appreciated. I did do some more research and the H5 is not the correct prop for this engine. Things like this absolutely drive me insane. I have no toleration for jobs done half asked just to save money. This is exactly what happens when the "short" way of fixing something happens. I have no idea if the crew jumped in the water to assess the prop but that would seem like the most logical thing to do and what I would have done immediately. Again, I am not there for this. I have all the faith in the captain that I hired of the job and can only assume they have done so. 

Again, please keep the comments coming along if there are anymore suggestions out there. I will keep you all posted when the boat is in Malta. 

Thanks again,

Bill
It's all Good

Hi Bill (It's all good),

the 1997 SM were not equipped with hydraulic gearboxes, and therefore don't have shaft brakes.
When the engine was replaced, what kind of gearbox was installed? Mechanic or hydraulic?

To start with the beginning, as we say in France, did someone dive to check if anything was caught in the prop?
As you mention, with engine off, throttle in neutral (and if you don't have a shaft brake system), your prop turns because of the water flow. If a piece of fishing net is caught in the prop, it turns with vibrations.
If a bearing of one blade of the AUTOPROP is seized, it will also turn with vibrations.In my opinion, the problem has nothing to do with the diesel engine condition.

In light winds as they had today, your crew should go diving and inspect the prop.
Do you know if, when the prop shakes the boat, the shaft that can be seen in the engine room turns also?

Good luck.

The G5 prop is not normal for a Super Maramu and it needs serviced more regularly than the H6.
Brompton told me this only two months ago.
The worst vibrations that I ever experienced turned out to be a sized gearbox due to the transmission heat exchanger failing and dumping the fluid, but the vibrations occurred  only when the gearbox was engaged with the engine running.
It is really important to find out when the 110 hp Yanmar was fitted did they retain/install a shaft brake which will rule the prop in or out.

Good morning,

 

first of all, these GRP hull shaped fairings are all different (as all AMEL models have different hulls).

This means a new mould for a Maramu cannot be made out of a Santorin hull.

 

You probably all know the design of the bow-thruster: above the gear-box and shaft tube, a strong GRP rectangle part is guiding the unit inside the well and counter-force the thrust when the bow-thruster is down.

This is the part that squeezes both foam seals under the well's top.

Charles, as long as your seals are in good condition and correctly squeezed (the lifting cable must be tensioned when in the up position), water will not come in more than when the fairing is in place.

The fairing is not more watertight than the big rectangle GRP bearing. Don't forget to put the securing pin before going sailing.

 

Now, I'm sure that any good shipyard in St-Marteen (thank you Eric) can make such a V-shaped part. Fortunately, AMEL is not the only shipyard on Earth to be able to repair GRP.

Charles, you should have it repaired locally before your Atlantic crossing because it will be better for your average speed....

 

Bon courage.

 

Olivier

Too bad about Amel not answering. If you get through Christian Dufourd he will do his best. He actually did go through the motions of finding the mold, but without success. We owners of old models are not worth much attention financially. So it goes .....

Re: [Amel Yacht Owners] Re: wire halyard

As reel halyard winches and wire halyards are antique technology, fairly dangerous to operate ( especially by anyone unfamiliar with the tendency they have to remove teeth ) replacement with a stronger modern specialty rope halyard and a self-tailing winch makes absolute sense.



Thoughtful, well consider modifications to elder Amel’s can be a good thing and the experienced sailors in this group will not hesitate to provide guidance. None of us have a real opinion about anything, you might have noticed!



Have fun with your Amel.

Thanks for the response I really appreciate it and keep it coming from the others. I think that there might be some communication difficulties right now considering I am in Boston and the captain and crew are only in communication 1 or 2 times daily via irridium data connection. Riza from Turkey has been in touch with us both and is helping the situation. I know anything is possible on a boat (speaking from past experience) but I am hoping that this is a simple fix like an autoprop bearing and nothing major mechanical. The boat was just prepped for this trip and surveyed in the past month. I look at this leg (Marmaris ~ Malta) as a shake down for the remaining 4,300 NM.

The bottom, prop were both cleaned before the trip, anodes replaced and all systems were tested.

BTW Bill: I have not forgot about your suggestions for a new mattress and Gardener Mattress is coming to visit when she arrives in Boston. I will let you know.

Cheers,

To Echo Bill's comment,

I had some "light" vibrations, could feel in some RPM range.
When I did the haul out, antifouling, C drive service, had the propeller entirely rebuilt and now the vibrations are gone, plus I gain 200 rpm !!!
Some say the propeller needs to be rebuilt every 2000 (engine) hours or 10 years.

Bill,
I should also have said that it could be the
AutoProp if the hydraulic shaft brake is not working or not
installed. That would allow the prop to spin with the motor
off and result in vibration.
But, that prop could simply be fouled. Did your
captain rule out a fouled prop, assuming a parallel problem
with the shaft brake?

Bill,
You state, " With engine off in neutral it
shakes the Amel drive." I assume you also mean under
sail and the propeller spinning? However, every Amel I have
seen has a hydraulic shaft brake that will stop the shaft
with the engine off...therefore no spinning.
Is the delivery captain familiar with Amels? Is
he familiar with diesel engines? I think that he might be a
lacking in knowledge about Amels, or lacking in his report
to you.
If I had to guess, you have a cylinder or two
not firing correctly, o'er possibly some sort of issue
with the transmission. And possibly a motor mount issue.
I am at Marina di Ragusa which is about 50
miles north of Malta. I have an SSB radio. If your boat has
SSB, and if your captain can operate it, I will be happy to
talk to him. Please let me know a time and frequency.
Contact me at the Italy cell phone below. FYI it is now1430

Also, I can give you contact info to haul out
in Malta with a yard at least casually knowledgeable with

Hi there

New owner
of a 1997 Amel Super Maramu in transite for delivery from
Marmaris, Turkey to Boston, MA. Recently the boat has picked
up a bad vibration in the prop shaft that shakes the entire
boat. With engine off in neutral it shakes the Amel drive.
The captain bled the injectors to be sure. It is currently
running a Yanmar 4JH4 110HP with under 500 hours and a
Burntons G5 autoprop. Captains guess is that one of the
bearings failed in a blade. Current ETA to Malta is 275 NM
in light air at 4kts. Anybody have any insight that can pass
along?

Re: [Amel Yacht Owners] Bad Vibration in the prop drive shaft

Bill & Judy Rouse <yahoogroups@...>
 

Bill,

One more thing.

I am fairly sure that AutoProp is undersized for that engine. At some point that boat was repowered. An AutoProp H6 would be appropriate for a 110hp engine. I have known other SMs to keep the undersized propeller, but do not know their experience positive or negative.

Re: [Amel Yacht Owners] Bad Vibration in the prop drive shaft

William Maffei <william_maffei@...>
 

Thanks for the response I really appreciate it and keep it coming from the others. I think that there might be some communication difficulties right now considering I am in Boston and the captain and crew are only in communication 1 or 2 times daily via irridium data connection. Riza from Turkey has been in touch with us both and is helping the situation. I know anything is possible on a boat (speaking from past experience) but I am hoping that this is a simple fix like an autoprop bearing and nothing major mechanical. The boat was just prepped for this trip and surveyed in the past month. I look at this leg (Marmaris ~ Malta) as a shake down for the remaining 4,300 NM.

The bottom, prop were both cleaned before the trip, anodes replaced and all systems were tested.

BTW Bill: I have not forgot about your suggestions for a new mattress and Gardener Mattress is coming to visit when she arrives in Boston. I will let you know.

Cheers,

Bill,
I should also have said that it could be the
AutoProp if the hydraulic shaft brake is not working or not
installed. That would allow the prop to spin with the motor
off and result in vibration.
But, that prop could simply be fouled. Did your
captain rule out a fouled prop, assuming a parallel problem
with the shaft brake?

If I had to guess, you have a cylinder or two
not firing correctly, o'er possibly some sort of issue

I am at Marina di Ragusa which is about 50

Contact me at the Italy cell phone below. FYI it is now1430

Also, I can give you contact info to haul out
in Malta with a yard at least casually knowledgeable with
Amels.

Hi there

New owner
of a 1997 Amel Super Maramu in transite for delivery from
Marmaris, Turkey to Boston, MA. Recently the boat has picked
up a bad vibration in the prop shaft that shakes the entire
boat. With engine off in neutral it shakes the Amel drive.
The captain bled the injectors to be sure. It is currently
running a Yanmar 4JH4 110HP with under 500 hours and a
Burntons G5 autoprop. Captains guess is that one of the
bearings failed in a blade. Current ETA to Malta is 275 NM
in light air at 4kts. Anybody have any insight that can pass
along?

Many thanks,

Re: [Amel Yacht Owners] Bad Vibration in the prop drive shaft

Bill & Judy Rouse <yahoogroups@...>
 

Bill,

I should also have said that it could be the AutoProp if the hydraulic shaft brake is not working or not installed. That would allow the prop to spin with the motor off and result in vibration.

But, that prop could simply be fouled. Did your captain rule out a fouled prop, assuming a parallel problem with the shaft brake?

Bill,

You state, " With engine off in neutral it shakes the Amel drive." I assume you also mean under sail and the propeller spinning? However, every Amel I have seen has a hydraulic shaft brake that will stop the shaft with the engine off...therefore no spinning.

Is the delivery captain familiar with Amels? Is he familiar with diesel engines? I think that he might be a lacking in knowledge about Amels, or lacking in his report to you.

If I had to guess, you have a cylinder or two not firing correctly, o'er possibly some sort of issue with the transmission. And possibly a motor mount issue.

I am at Marina di Ragusa which is about 50 miles north of Malta. I have an SSB radio. If your boat has SSB, and if your captain can operate it, I will be happy to talk to him. Please let me know a time and frequency. Contact me at the Italy cell phone below. FYI it is now1430 my time.

Also, I can give you contact info to haul out in Malta with a yard at least casually knowledgeable with Amels.

Hi there

New owner of a 1997 Amel Super Maramu in transite for delivery from Marmaris, Turkey to Boston, MA. Recently the boat has picked up a bad vibration in the prop shaft that shakes the entire boat. With engine off in neutral it shakes the Amel drive. The captain bled the injectors to be sure. It is currently running a Yanmar 4JH4 110HP with under 500 hours and a Burntons G5 autoprop. Captains guess is that one of the bearings failed in a blade. Current ETA to Malta is 275 NM in light air at 4kts. Anybody have any insight that can pass along?

Many thanks,

Bill

wire halyard

zetta.traill@...
 

on my 1980 Sharki there is the original wire halyard for the main sail. All my advice has been to replace it with  rope halyard.

However being an Amel and reading the forum's advice not to alter the original design I am hesitant.

Can anyone offer me a reason for not changing to rope.

Thanks,

Warren
