Re: Down wind pole corrosion damage

John Clark
 

Hi Thomas,
   Good catch!    I noticed Annie's short poles collect water inside.   I have toyed with the idea of drilling a small drain hole to let it drain.     Letting them stand upright in the sun for a week or so drains them but I can't always do that.  (Admittedly sometimes just lazy and leave them out...)

Re: Yanmar 4jh3-hte overheat

Hi Duane,
  I had a similar experience right after I purchased Anne,  first indication of issue with the impeller was as you said a different sound. We had no overheat alarms just a much more pronounced exhaust sound.   This was with the TMD-22.     Lesson for all is to listen to your vessel...she will tell you is something isn't right.

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.

Duane,

 

I am a little confused (normal for me). Is the engine fixed? Did you resolve the overheat issue or are you still experiencing hot temperatures at higher RPMs?

Re: Deck Repairs to Amel Mango

Hello Ian,

We are resurfacing the decks of Mango #29 right now.

We sanded off the loose "molded-teak" and have sealed with a 2-part high-build sealant. Then we will top with some sort of a surface treatment / non-slip. 

The contractor we are using has done several boats with the same technique. 

I will dig up more information about the steps and materials we are using. Feel free to reach out to me if I don't get back to you quickly enough.

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: 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.

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.
