Replacing eng mounts

Alan Grayson
 

Hi All, I'm replacing the yanmar 4jh3-the eng mounts. It looks like I need to lift the eng frame 2 inches. There is a rubber boot that connects to the hull at the bottom of the C drive. If I disconnect the hose clamps at the top of that rubber boot will any oil spill out and will that allow me to lift the frame up.

Re: [Amel Yacht Owners] Shock from windlass

You’re talking about the center pole on AC plugs, right?  Nothing AC alive on Kristy when shock occurred.  No shore power connected, although worker might have dragged a 110AC extension aboard.

When you short a 12v battery between pos and neg, you get a huge arc.  Why wouldn’t that shock the crap out of you?  Direct current shock is what we use to shock the heart back into rhythm, gives the patient a big jolt.

Kent,


When you measure that potential Bill R suggests, be sure you measure it both as AC and DC voltages.  If you find a significant AC voltage between the windlass and earth, I would unplug from shore power right away, confirm that the voltage has gone away, and stay unplugged until the problem is diagnosed and fixed.

If there is any kind of cross connection between an AC "hot" wire and the DC system, or the bonding wires it has the potential to be quite dangerous.

Re: [Amel Yacht Owners] Suddenly screaming noise from the bowthruster and not moving the prop anymore

Hello Martin,

Thanks for your fast reaction. The SM does not have a clutch like the 54. It's either the top- gears or the gears on he foot that failed. I will see what's wrong after the haul out next week.

Best regards,

Hello fellow Amel owners,


I just moored my boat in the El Portet Marina in DENIA, Spain and almost done, the bow thruster did not function anymore and made a screaming noise. The prop is still there but it can turn almost without any resistance.


Any idea what can be wrong and how to repair is very much welcome.

Thanks Bill, I will go to the boatyard next Wednesday for a already planned haul out. The broblem must be on the foot or on the top gears.

There can be several causes.

Nikimat gave you a very complete answer, but to find the exact cause, you will need to disassemble the bow thruster.

Thanks, If only it was that simple... Our pulpit is a lot simpler in construction, and I have a good view of both sides of the axle, but both have flared heads.  There is obviously a magic trick I am missing!  

I would be fine changing it out for a bolt if that makes sense, but surely there has to be a better way to disassemble than cutting it apart...

Thank you for the tip, I sometimes had problem finding o-rings, thrust it will be less of a problem in the future. Will definitely have a o ring splicing kit aboard

Making O Rings

rossirossix4
 

We have had really good luck with an O Ring Splicing kit.  You can buy these in metric or inch versions and they come with a tool that helps you size and cut it AND line it up when gluing. e.g.  https://www.theoringstore.com/index.php?main_page=product_info&cPath=607&products_id=18578&zenid=9ed43caca167650bcb1de3dbd43b3748 They come in a plastic box kit.  You can also find them on eBay and Amazon and I think Buna and Loctite are the best known. It is almost impossible to carry all the O ring sizes we have on our boats.  Sometimes, if an O ring is missing you have to buy several "guesses" to fit it and a kit eliminates that problem as you can size it by measuring diameter and length in place before you make it.  Looked around--this guy made a YouTube on it https://www.youtube.com/watch?v=MniGPMJb1H0  and this boater made one https://www.youtube.com/watch?v=pDb5CrayM-U&t=14s You would think that the glued splice would be a weak point but as a test have stretched these beyond recognition without having it separate at the splice.

Re: [Amel Yacht Owners] Foghorn?

eric freedman
 

We have a Raymarine VHF with a fog horn. The horn speaker is mounted pointed down directly above the first Mizzen spreader. It has a number of options. It only broke once when we were hit by a breaking wave in a hurricane. It has work flawlessly. We have a handset at the helm and at the nav station.

Running a wire from the mizzen to the nav station is very easy. Not so easy from the main mast.

Has anyone fitted a foghorn on the main mast?  I don't see too many boats with one, but we were in fog for 8 hours earlier this year, and an automatic horn driven by the vhf would have been great.

 

If you have one, would you recommend the brand?

Re: [Amel Yacht Owners] Shock from windlass

 

Kent,

Earth is Earth and not bonding or Negative pole on a battery or battery bank.

In the US, Earth is the center pole, is the green wire, which terminates on a copper rod driven into the earth. On an untouched original SM, Earth is the center pole, green/yellow wire that is not the green/yellow bonding wire.

Hello Amelians,

I just heard from the yard where I am having work done on Kristy.
One of the guys in the yard guy a shock while operating the windlass by the switch on the windlass and at the same time touching the lifeline rail.

They don’t have any clue about the Amel “ floating ground” and want to blame the shock on the floating ground. I assured them that this was highly unlikely, but I am not sure what is going on here.

Both the windlass and lifeline rail are exposed to sea water.
Are the lifeline rails connected to the bonding system? If so, where is the connection?
Is the windlass connected to the bonding system? If so, where?

Does anyone have an idea of how I should go about trouble-shooting this “shocking” problem?

The yard worker was using the button switch that raises the anchor, which is working as it should. The button switch that lowers the chain works only intermittently, and the up and down toggle switch at the helm works correctly. There was no shock when touching the windlass and rail unless the up switch was activated. The windlass did bring the chain up.

This sounds like a potentially dangerous situation, so I am anxious to find the problem and get it repaired.

Thank you for any advice. I will report what I find.

Happy sailing, Fair Winds, and Respect de la Mer.

Kent,


I've been working on my windlass recently.  The motor wires directly to the negative battery terminal.   The switching happens on the positive side.

If your guy was touching the lifeline and the windlass and got a shock, I'll bet the positive was from the lifeline, and the negative for a circuit was from the windlass. 

So the wires in the lifeline is the thing to check first.  Check the voltage from the lifeline to the motor casing (I'm assuming there is some connection from the motor negative to the casing, which may be inadvertent).

Also, if one button works and the other doesn't, it could be the button, or it could be the control box.  My control box welded the contacts on one side for a runaway condition.  After "repairing" the control box, the up button works but not the down button because some of the wires from the solenoids to the control button spade terminals inside the box came free and I had to resolder them.  Apparently I was successful on the up button but not the down.

Re: [Amel Yacht Owners] Foghorn?

 

Duane,

Based on a recent conversation, I think that you are going to be buying a new VHF. Almost all new VHFs come with a foghorn option that sounds through an external speaker. The easiest place to mount that speaker below the radome on the Mizzen.

Are the lifeline rails connected to the bonding system? If so, where is the connection?
Is the windlass connected to the bonding system? If so, where?

Does anyone have an idea of how I should go about trouble-shooting this “shocking” problem?

The yard worker was using the button switch that raises the anchor, which is working as it should. The button switch that lowers the chain works only intermittently, and the up and down toggle switch at the helm works correctly. There was no shock when touching the windlass and rail unless the up switch was activated. The windlass did bring the chain up.

This sounds like a potentially dangerous situation, so I am anxious to find the problem and get it repaired.

Thank you for any advice. I will report what I find.

Happy sailing, Fair Winds, and Respect de la Mer.
