Hello Stefan;

 

After the first season aboard Kokomo about 5 years ago, we started looking for a solution for the “banging” you refer to. After a few iterations of trying different solutions, we came up with our final solution that we affectionately refer to as the “slap slap device”.

 

It basically consists of two layers of mesh fabric (the same material cargo straps are made of), strengthened by 1 inch mesh straps sewed in both directions every 18 inches. The two layers are then sewed together forming several pockets that we have inserted 2 mm waterproof foam for floatation and sound insulation. This is custom made to fit the entire stern from the trailing edge of the rudder to the back of the transom and all the way to the sides about 12 inches above the water line. It has several long straps for attachment to the lifelines/stanchions.

 

We simply deploy from the stern and slip it under the stern from the sides. We just attach four of the straps to the lifelines (just at the forward/rudder end) and let the rest happily float and move up and down with the water movement, under the stern. This provides an insulated barrier between the water line and the hull, where the hull rises out of the water at the stern and the sound originates from.

 

It takes one person about 5 minutes to deploy and retrieve. We simply fold and hang on the life lines, after retrieval, to dry.

 

This will handle almost all conditions that we typically anchor in, where the boat is facing the wind and waves. It does not do as well when larger waves are coming from the stern, but does help to dampen the sound (this is not a common condition). We also deploy her at marinas/harbors where small wavelets are present. As soon as deployed, it transforms the master cabin from a drum machine, into a quiet place to rest and relax. It is on extremely rare occasions that we have to move to the forward cabin due to sound.

 

We have now utilized our slap slap device for 5 seasons in the Med. It has been used in all conditions from 2-3 knot currents to 35-40 knot winds. She is almost like new and should last for a few more years. It has made a huge difference for us, as the master cabin was one of the major selling points of the 54 and we could not imagine, not being to utilize it.

Re: Lens-shaped bolt nuts

Ryan Meador
 

These are used in a few places on our Super Maramu, most notably on the cockpit table.  Amel replaced one for us in Martinique and I'm pretty sure they just called it a "special nut".  Google translates that name as "lentil nut", which is a very apt description.  Thanks for the source!

Re: Yanmar 4jh3-hte overheat

Arnold Mente
 

Hi, 

after experience in dirty harbors with running the aircon and full sea water filter, overheating of engine friend ones SM I decide to install the attached instrument. It get installed after water injection in the exhaust and acts much faster then the engine temp control. The temperature of the exhaust increasing much faster then the engine himself. With this you can control the sea water filter and the impeller!!!

Re: Yanmar 4jh3-hte overheat

Mark McGovern
 

Duane,

Generally, temp sensors work off of resistance with high resistance when cold and much lower resistance as the medium gets hotter.  You can use a cup of room temperature water and boiling water and measure the resistance across the wires of the sensor and see if there is any difference.  However, you would need the actual specifications on the Yanmar temperature sending unit to test it definitively and make sure it is working properly.  I suppose you could buy a new sensor, test it the same way and compare the results to the old sensor.  If the results are similar you could assume that the old sensor is working properly.

A few Amel owners have taken to installing a secondary separate Exhaust Temperature sensor and alarm.  You can read about it here:  https://amelyachtowners.groups.io/g/main/message/17290?p=,,,20,0,0,0::Created,,muffler+melt,20,2,0,29759579

Re: Yanmar 4jh3-hte overheat

 

Check the sea chest side of the transmission oil cooler. This should be cleaned every 2 years. Small pieces of debris that get past the sea chest strainer will block water from flowing through this cooler to the engine. Overheating happens because water flow is restricted at higher rpm.

My concern is that the gauge read close to 100 oC and now I'm concerned about the sensor.  The lights and buzzer on the panel test ok.  Is there a way to test the sensor?

Just for background, the boat had been hauled out in Grenada for three months.  When we put the boat back in the water the engine sounded not quite normal and so I was watching the gauges closely.  It turned out that the impeller had shed all of the vanes!  I had checked the water in the exhaust when we first started up and it appeared normal so the impeller must have died after that.  Luckily the vanes were all in the hose between the water pump to the turbocharger cooler.

Re: Down wind pole corrosion damage

Thomas Kleman
 

Bill- thanks as always for your info and speculation. The rivets all over the pole are quite brittle with heads falling out so I'm concerned water ingress and corrosion played a large part. I found the damage as I was preparing to fix several broken rivets. When the welder and I do the autopsy we will know the cause.  The pole been rigged correctly the handful of times I've had occasion to use them. Not sure how long this damage has been here as it was mostly under the wear guard and thus hidden. The pole is of simple 3 part construction so no big deal.....but I might add some corrosion protection or sealant to the joint and rivet areas.

Volvo D3 110i-A raw water pump and damper

ngtnewington Newington
 

Regarding replacing the Raw water pump Volvo 21141637

It looks like there is also the option  of the Johnson pump VP0030DA as a replacement that is about half the price of the Volvo one. Thanks for that info Arno.

I reckon that the lip seal must have worn a slight groove in the shaft as Gerhard suggests, because 500 hours is not that much…..

So now we narrow it down to buying the new shaft kit and /or the Johnson pump if I can find it in the UK.

Given how important this is I think I will buy a new Johnson pump and a new kit for the existing Volvo, the full service kit that includes a new shaft. Then I can replace the old with the new and rebuild the old and keep it ready to go.

I am gradually building up my spare parts for the Volvo D3. As I have some extensive cruising plans. 

I am a keen reader of this forum, as many of us are. It is very useful and interesting. There is lots of knowledge and experience out there and I am delighted to tap into it…

On that note, DAMPER PLATES. My engine hours are roughly 2600. I notice a gentle “clunk” when I engage forward gear. It is quite normal for most boats but I get the feeling it is slightly more pronounced than it used to be. It is not silky smooth, such that you do not even notice going into gear. What should I expect?

This is on my "keep an eye on it" list.

Does anyone know when it is typical in terms of engine hours that the damper rubbers need changing?  I have done this job on a 50hp Kubota whilst the engine was out of the boat and it was not difficult. However on the Amel, I would rather leave the engine where it is but notice that since the C drive is pretty much fixed and best left alone that means sliding the engine aft. It looks like this is realistic, one could use a halyard to lift say 90% of the weight then  pull the bolts from the mounts and slide it aft on the steel frame, without mucking up the adjustments on the flexible mounts. Has anyone experience doing this on the 54?

Bill,

The Load (the fan )  is connected to the to  the capacitor as well as the brown wire both being in parallel are then connected to the other side of the fuse.

The black wire is hooked up to the other side of the capacitor.

If the load was connected in series with  the capacitor, it would be the brown wire connected to the capacitor and then the other side of the capacitor connected to  the fuse–Which they are not.
