Re: Bulkhead Thickness & Screw length

Hi Richie,

The location you selected would not be my first choice, as (at least on our boat) that side of the bulkhead is covered in the same vinyl material as the headliner.  No doubt you could drill through it, but it makes more sense to me to mount it directly to wood.  If you want to go ahead with this plan, that bulkhead appears to be about 25mm thick.
IMG_20200514_094644.jpg
There's a large wooden beam directly under the mainmast, which I assume hides the compression post.  It's 17 cm wide, with a bit of a radius at the corner.  A 15 cm plate might just fit on the flat part.  I'd see if you can put it there, tucked up close to the bottom of the electrical panel (to the right of our fire extinguisher in the photo).  I can't hazard a guess as to how thick the wood is.

Another likely spot is forward of the head door, directly under the hatch.  That bulkhead is about 15 mm thick.
IMG_20200514_094701.jpg

Yet another option might be the shelf above the forward hanging locker.  It's pretty far outboard, so I'm not sure if it meets the requirement of "directly under the mast".  There's enough space for the plate in between the two doors on our boat.  If you want to hide it behind the door to the saloon, it will fit there too.  The front face of the shelf is about 18 mm thick.

I hope this is helpful, and I also hope the dimensions on your boat are the same as ours.  This was a fun little diversion while I'm on conference calls.

 On our SM the sonic speed,  the one with the two sensors,  that is connected to Hydra 200 is giving zero speed on the hydra 2000 monitor. 
This was probably due to the loss of the neoprene cap of the aft  sensor . Unfortunately this probe is out of production from long time.

Hi Folks,

I’m a recent SM purchaser and as part of my boat registration procedure I need to attach a stainless steel plate (10cm x15cm) etched with the registration details to the bulkhead under the mast. On a Super Maramu - sight unseen I’m figuring the best location for ease of access and minimal visual impact is above the door from the front cabin to the saloon - on the front cabin side. 

 

I can't access the boat at the moment to take measurements as she is in Greece and I'm in Ireland (coronavirus..no flights) but I have a local who is willing to attach the plate for me if I send him all the parts & fixings.

 

I have a simple question but I would really appreciate an answer. 

 

What length stainless steel wood screws should I use to attach the 1mm thick plate securely without causing damage from bulging/poking through the bulkhead?

 

Kind regards

 

R.

FW: [AmelYachtOwners] TMD22 stainless steel muffler diagrams?

Hi Ryan and Kelly. All early Amel Super Maramu boats had stainless steel mufflers and the one in the picture of your boat is indeed original equipment. The change to Vetus plastic occurred when the Yanmar was made standard equipment.

 

The change was made to Vetus primarily to get a reduction in engine room noise. The plastic Vetus mufflers “pant/expand and contract” as each cycle of raw cooling water is injected into and blown out of the muffler which makes the woosh-woosh sound that is heard at the exhaust exit on the hull side, The vetus mufflers were wedged in with a layer of plastic foam on each side and tied into position, This allowed them to wiggle around with no hard contact areas that muffler could make music with. The other advantage of the Vetus is they are non-corrosive and last almost forever. The major disadvantage is that the Vetus will melt rather quickly if it does not get the raw water cooling supply as it comes out of the diesel’s cooling system.

 

I had a client down here who wanted to replace the stainless one with a exact copy as Amel didn’t have spares. The fabricator cut the bottom off and was able to see the details he needed.  $ 700 in 2001 and the guy who did it has retired .

 

Have fun with your Amel, Joel

Re: water pressure regulator adjustment

 

That's original. I don't have any info. I think I would eliminate it, although it would be convenient to keep the pressure gauge. I think modern pumps regulate pressure good enough.

Re: Mizzen furler gearbox, A54 peculiarity?

 

I don't know, but I can guess.

I think Amel used that same "mechanical furl" gearbox with some vertical electric furling motors (later model 54 main furler). This may be the reason the drain holes were taken away.

Re: Mizzen furler gearbox, A54 peculiarity?

Hi Thomas;

 

We had the same stiffening within a year of purchasing Kokomo. It got progressively worse to a point that we felt we may be damaging the gears by placing the amount of force required to furl and unfurl. I removed the gear box and found, as you did, a lot of water inside the box. We were in a situation that we did not have enough time to try and figure out how to get into the gear box and find a permanent solution. We drained it, let it dry out in the sun for a day and sprayed a good amount CorrosionX inside a temporary measure. That was four years ago and the furler has been super smooth since.

 

Happy Sailing;

Re: sonic speed on SM 2000

Oliver Henrichsen, SV Vela Nautica
 

Hello,

As the old B&G Hydra system gave up on our 54, and also the sonic speed system failed. I did not see a reasonable way to go on and repair the old system. 
So we renewed the windvane and use Triton2 instruments. 
To replace the sonic speed sensor, we choosed the Airmar DST800 tridata sensor. It fits in the through hull of the old deapth sensor and givs all, speed, deapth, sea temperature. 
With that renewal comes an NMEA2k bus and all the old Hydra central cpu and extension processor and all the wiring goes off. 
In that way we did not need to drill a new throughull and keapt the compfortable sonic speed without paddle wheel.
