Thanks, Kent - how did you tab that in, or did you use mechanical fasteners?

Hi John,
Olivier also had this listed as suspect for me, but suggested to try re-packing with grease. 
It looks fine, the belt-drive components are all ok, I think it's the worm-gear which is worn. 
It will get replaced at some stage, but down the list a bit at the moment.
Cheers

Hi Dean,  noisy is not good.  My mainsail furling drive sounded bad (looked bad too, was on survey replacement list) at purchase and failed on sail back to US.  Bearings had been dry and ground to dust.

Courtney, I agree it indicates an over-temperature condition. Not sure why, as the ambient has not been very high. I suspect a glitch, possibly to do with lightning - there has been some activity in recent weeks.

The (staysail) furler MEJ 1.02 still operates, although very noisy. I regreased the box but it did not change anything, so I'm living with 'noisy' for the moment. Maybe I can pick up a second hand one somewhere!

Thanks all.

I believe 7 beeps and a pulse is a heat alarm mine was fried by a near lightning strike.  A refurbished unit is about 750$ and a new unit about 1400$ sorry for the problem but easy fix as 4 screws hold the unit in and you just plug everything into the lower 'spare' until the fix

Hi folks,
Arrived at the boat late last night.
The prize goes to Courtney, it was coming from the Boxtron Unit in the bow locker!

The alarm was a sequence of 7 beeps then a pause.
I disconnected the unit and the alarm stopped.

Today's task is to find out why.

Will keep you posted...
Re: [Amel Yacht Owners] Re: Cautionary Turbo Tale

Olivier, Thanks for confirming that I was not missing any sort of filter. I understand the importance of not restricting air flow and I am only planning to install a wide mesh (1/4 inch) screen over the intake  and making it as you suggested a larger diameter surface area to increase area and emit more air. I can not believe that my engine even started , let alone achieve 1800 rpm with a tightly wound wad of paper towel completely plugging the intake at the turbo. I agree its a rare occurrence , but somehow rare occurrences , have been very common in my life. 
Thanks,
Pat

Hello Pat, Jean-Pierre, Duane and all SM and SA owners,

AMEL never installed any air filter on the PERKINS PRIMA and VOLVO TMD, but only an air muffler, in order to reduce the noise at the air intake (which can be as loud as at the exhaust). Then , with the YANMAR 4JH3, an air grate was included by the manufacturer.

For the PERKINS or VOLVO users who would like to install a kind of filter (like a sock or stocking) on the existing air muffler, beware that you will reduce the volume of air going into the cylinders (or turbo). In fact, you should in stall a piece of metal/plastic that would increase the intake diameter, and then install your sock/grate onto the larger diameter.

My advice: Don't change anything (Bill R may agree...!!) as the chance to get a towel in the air intake is poor (as long as you keep your engine room tidy!!!).
Don't make a Murphy's law of a very rare incident (a paper towel forgotten close to the air intake).

Enjoy motoring (and sailing...)

Olivier

Does the breather line (usually a rubber hose attached to the top of the valve cover) go to the air cleaner that feeds the turbo?

I'm not sure if this is the right place to ask but we would really like to have a day out on a Amel 54 to see what she's like to sail. We are living in the South-Caribbean and ideally would like to meet an owner in the Caribbean.
But other offers are also received with gratitude.

We are trying to figure out if a Amel 54 is right for us. It would mean a huge step in our budget so we are trying to figure out if we are the right people for this great yacht.


Thanks in advance to anyone that help us making our mind up.

There is no filter on my air cleaner, just an inverted basket to stop nuts and bolts from entering the turbo… my previous boat almohad a TDM 22 and no filter there either.

Re: [Amel Yacht Owners] Re: prop shaft bonding

James Alton
 

Bill,

  I think that you understand metals and corrosion pretty well.   In my experience, a really good bronze can survive the Marine environment for the life of the boat unprotected but those types of bronze are not strong enough to make a thin prop blade out of.  Props as I understand things are made of stronger but more corrosion prone alloys, hence the need for protection.  I am quite sure that you are correct that the bronze prop on my Loki is protecting the stainless shaft galvanically.

  We took care of a customers Gulfstar 54 over the period of 20+ years and tried various coatings for the twin PYI feathering props and even Prop Speed failed after 6 months by bubbling off.  While the coating tended to fail first on the back side of the leading edge of the prop, bubbles would form over all of the surfaces with the boat just sitting.  I think that the zincs for the PYI Max Prop might have some magnesium in the alloy to increase the level of protection but at any rate the anodes did corrode away on those props much more quickly than the common shaft zincs.   Imo there is a definite  connection between the rapid corrosion of the anodes and the lifting of coatings on underwater metals such as a prop.   

  I have had to replace a lot of wood in boats damaged by the Alkali buildup and have seen a few nice wooden boats completely destroyed from serious over zincing.  The amount of damage to the wood is as you allude a function of how heavily protected the metals are.   While our  fibreglass hulls are not affected themselves, you can sometimes see some (generally minor)  alkali damage to wooden backing blocks under protected bronze seacocks.  For some reason, bronze alloys are the worst about building up the Alkali when protected than stainless or monel.

I wouldn't expect zinc to protect the stainless in a cutlass bearing or under the packing.  The problem there is low O2 content of the water, resulting in incomplete formation of the protective oxide coating. It's not the kind of galvanic corrosion that zinc prevents.  

In most boat's running gear the stainless is the most noble of the connected metals, so it sits there happy while the bronze dissolves.

I have little first hand experience with wood boats.  I know of the problems with al kali attack on wood, but I thought that was only a problem when the metal was significantly overprotected by excess zinc.  If I ever lose my mind and buy a wood boat, I'll remember what you say here!

Good info Bill. 
Not to reignite another metallurgy and salts of acid talk, but I now refuse any chlorides in the bilges or sea chest. I had been advised (not by Rouse) to use them freely. Your chemistry is sound.

It is very strange the highly variable life of the SM manifold. 


I took ours (20 years old) out last year, cleaned it, checked the metal thickness, and in every way it was like new.  Other than a bit of green patina on the outside surface, it looked as though it had been manufactured yesterday. I gave it a new coat of black paint, and it is back in. Unless something changes dramatically, it should give us good service for many more years.

Both the main seacock and the manifold should be connected to the bonding system, although the presence or lack of of bonding would have no impact on _external_ corrosion of those parts.

Maintenance might have something to do with it.  Allowing salt to sit against the manifold from a tiny leak at the hose joint would be a bad thing.  Stop the leak, and be sure the solid salt is rinsed away. Such salt can create a conductive path from the stainless hose clamps to the copper manifold that would not be a good thing.

I have heard that some people will drop a "chorine tablet" (Calcium hypochlorite) into the seachest to discourage bio-fouling.  This would also explain a short life for the copper manifold (and any other copper parts in the seawater piping!) and is (in my opinion) a bad idea.

Otherwise than those guesses I have no idea what happens to some of these manifolds...  copper should have a very long, almost indefinite, life in seawater service.
