Hi,

I searched car parts of various makes and models till I found some that fitted. I went around all the car businesses in Noumea to find ours. They've done about 4 years so far and going well. Im sure the same would apply elsewhere.

I've looked at the forum and found Bill R's note that they are rated at 400 Newton (90 pounds), and I measure the length at 22.5" extended length and a stroke length of 8".


The problem is I cannot find a gas strut with bolted connections.  They seem to come in clevis and ball joint.


Does anyone have a source reference?

Hi Duane, I am not on my boat for a couple of weeks, but I ordered mine from a company recommended on this forum.  Reasonably priced, stainless, quick service and shipping, and fits well.  I’m sure you can find the conversation with a bit of searching..

A1A1N40-250-608/400N 316L Stainless Steel
Meaning a stroke of 250 mm with 608 mm overall
400 NM resistance
The stroke is 8 mm
The Diameter of the cylinder is 19 mm
With 8 mm hinge on each side.

Took a few weeks to build
They were $125 each (and free shipping).

These were the highest standard they are, guaranty for 10.000 opening... 
They also had a cheaper standard line.

That is literally "the trick" to opening the shower mixer then there is no screw at the top.  You use a screwdriver to pry it off.  Given that this forum is comprised of people from all around the world, many of whom are not native English speakers, I find that posting pictures in addition to text can be very helpful, even for something as "simple" as a water faucet service.

Thanks Dean, it’s very useful information; I still need to learn a lot about boat electronics. 

Yes, my goal is to have a redundant chart plotter / navigation tool and it’ll be a good project to get more familiar with the system. 

I’ll get started on the practical implementation when we get back to the boat at the end of August and will report back my findings.

You will have no heading based information because the PG500 compass is connected to the MFD directly.

I understand the Hydra CPU only has one NMEA output, and this is connected to the MFD Port 2 Inputs.  You can piggy-back a connection, but for permanent use I would try to find a proper 0183 sharing device (one input - two outputs, I haven't looked but I'm sure they must be available).

Hi Dean,

Many thanks for the detailed explanation!

Re point 5, it would be interesting to have the details of the wiring and MFD configuration. 

On a side note, I will be looking to add a NMEA to WiFi gateway to feed data to phone/tablet apps. Do you have a quick answer for the best wires to get NMEA into that gateway? Ideally GPS/Hydra/AIS data would be available even if/when the navnet isn’t working.

2. I have reconfigured the MFD12 chart plotter to output GPS, Time, Heading, Motion and Waypoint data on NMEA0183 port 2.

3. I have connected MFD port 2 output to both the Hydra and the ICOM 505. (Port 2 output was previously unused and Port 2 input is already connected to Hydra output, so that is a sensible connection).

4. Hydra and ICOM now both correctly display position and time. 

5. Hydra now displays heading and waypoint information, and can correctly display wind direction etc. 

6. When the GP150 comes back repaired I will slot it back into the system, wired to the MFD and Icom as before, but I intend to leave the MFD feeding the Hydra as I have it now.

Point 5 above solves the problem I posted about last year where Hydra would only display angles relative to the boat. It can now also display correct wind direction as well as the waypoint data. Happy to share the wiring and MFD configuration changes as required.

Really appreciate the info and link. Amazon only have this in 12v but have found suppliers in US (about$300) and EU. I also have an old cutting board to use as a backing plate. Should be easy install.
Amel have advised they have the gear/sprocket for the original AMFA pump, waiting on price from them so as to make a decision which way to go.

Re: Negative leak to bonding system

ngtnewington Newington
 

I am now back on my boat in the Azores and have installed the new 175A alternator.
The leak test yields no leak, remember there was a negative leak to the bonding system.
The excitation circuit is as before but I have added a smart regulator.
The alternator kicks in straight away. Do not have to rev up to 1500 for it to kick in!

So great result!

What is the conclusion?

For sure somewhere within the old alternator there is a leak from negative terminal to the frame, tested it with multimeter.
We will not know until the alternator has been serviced exactlywhat is the problem. I will report my findings in due course.
On my next visit to the UK I will send it to the Leece-Neville distributor for service.

I also dived under the boat to check the anodes, and sure enough the prop anode has lost say 25%. So well done anode! 

I believe it prudent to always fix a prop anode in all but wooden boats for just this situation.

There are many aspects that affect the life of a diesel engine. If properly maintained and regularly run under proper load it is not unusual for a diesel engine to run in the 15,000 to 20,000 hours. We cruise for about half the year currently and we only put about 200 hours per year. So the lifetime of a diesel engine could last well beyond the average cruising life time.

Betreff: Re: RE: [Amel Yacht Owners] Bow-Truster overheat

 

Hello all AMEL 54 owners,

there is indeed a thermic switch on the bow-thruster motor. It is connected to one of the carbon brushes. If you have already had it stop the motor, several times, or you purchased a used boat and you don't know about the over-use of the bow-thruster by the former owner, it may be time to check the carbon brushes of this motor.
Indeed, worn out brushes lead to warming up where the brushes make contact with the rotor. And worn out brushes make the motor less powerful, then you may use it a longer time for the same amount of thrust.
If you see a lot of carbon dust around your BT motor, it's time to check/replace them.

Moreover, when AMEL says that you should turn ON the generator when using the bow-thruster (and the 100A battery charger), this is because the bow-thruster will work with higher voltage (the voltage drop will be less if the charger is ON, and as the main engine alternator is not charging much at low revs). With higher voltage, the amperage will be less, the warming up of the thermic switch too and the wear of the carbon brushes too.

Now, I agree that you don't absolutely need to turn on the generator and battery charger in any conditions. But do it if you enter a harbor that you don't know (you may use the BT a lot) or if the wind is strong.

In the french Navy, when a vessel enters a harbor, every means of power is systematically turned ON, in case one fails. Bill R will tell us how they do in the US Navy, but it may be the same.
This was the idea of Captain AMEL and Mr. Carteau when they decided to give the "Generator ON when docking" advice.

Rüdi, don't worry about too much wear on your generator, it is a very resistant piece of hardware....


Keep enjoying easy dockings!!

Olivier

Reudi;
 
The main reason to run the Genset while using the bow thruster is not to reduce the load on the batteries. Putting out 400-500A for short bursts will not have a significant negative effect on the batteries.
 
By running the Genset you are maintaining a higher voltage to the bow thruster, reducing the current requirement and thus reducing the heat generated in the bow thruster and all associated wiring supplying the bow thruster. This will maximize the time the bow thruster will function before the thermal cutoff kicks in.  Therefore for us it is not a calculation of battery vs. generator life, but an issue of safety. A few extra seconds of bow thruster availability may make a big difference in the result of the maneuver.

Thanks for all your thoughtful responses. This is a great forum and I have learned a lot within a short time about AMEL. I love it!

Here some comments on your responses: 

I’m not using the bow truster more than 5-6 seconds per burst. When I use it, I’m carefully not to overdue and I usualy waiting to cool down a bit between 2 burst. Thats why I was wondering how fast it was paused by the system….

No, I don’t use generator while use the bow truster, as AMEL and many others recommending. I agree with Thomas about it. 
- In one hand the Engine is running always when use the BT and is supporting the batteries as well . 
- On the other hand I do not extensively use the BT so my Batteries should be able to carry the load. 

- AND most important; I don’t want to shorten the live of my GenSet just to help the batteries a bit.
In my opinion is; The live of a Diesel engine is shorten by too many short usage without much load and without running it at leased 30min at a time. When I turn the GenSet on, I use it for many things at the time, Laundry, Water-maker, heater, charging, whatsoever. Therefore it runs at leased an hour when it’s on.

BTW: 
We don’t had the 425A fuse on #55 either. Olivier recommended to install it and also an emergency shutoff in the BT compartment . So we did. ;-)

Hi Mohammad and Aty,

So you don't have that 425A fuse on Kokomo?
It'd be interesting to have other data points. 

When we started seeing A54s for sale, someone from the yard in Hyères told us Amel started to fit the emergency disconnect on 54s  after instances of incidents where the bow thruster wouldn't stop. The thermal switch should provide that safety stop, but maybe they felt there should be a manual override too, in case.

By the way, it was in the same sentence as "have the genset running when you use the bow thruster" that raised a few eyebrows in this group a while back. At the time, not knowing better, I took it for granted. Sufficient and safe, yes. Necessary?, I'm not sure. We don't do it anymore as we don't go to marinas that much and when we do, we try to play the game of least-bow-thruster-usage to improve our handling skills, and our batteries can handle the high current discharge.

Hi Thomas;
 
Your fuse may have been added on because I've heard some surveyors and insurance companies regard this situation as unsafe and will require the fuse to be added. I'm pretty sure that we were told by Olivier during our survey that the bow thruster is directly connected to the batteries. When I inquired about the reason, I believe the response was that Amel felt that the safety of the boat, when absolutely needing the bow thruster to be operational, was more important than the possibility of the bow thruster being damaged due to overuse.
 
The emergency disconnect is a manually operated switch which would require intervention form a person to stop current flowing to the bow thruster.

Hi Mohammad,

On Garulfo (54-122) there is also a 425A fuse on the positive cable and an emergency disconnect (big red button), both housed in the box inside the forward locker. 

I recently found the emergency disconnect to be rusted frozen so it's on the list for replacement. 

I would encourage others to test the emergency disconnect as it has a carbon steel backing plate and is mounted without any kind of waterproofing so is bound to rust.

Hello Reudi;
 
Yes, the Amel 54 has a thermal cutoff to prevent damage to the thruster as well as continuous high current draw (Around 550 Amps at 24V) which could lead to fire on board. We've had the thermal cutoff kick in  only a couple of times and it has reset in a matter of minutes. We have not timed the exact reset duration.
 
I'm not aware of any adjustments in the thermal cutoff. The bow thruster has a direct connection to the batteries without a breaker. The thermal cutoff is the only safety items preventing major damage to the thruster and/or wiring.
 
Try to use the thruster in bursts (less than 15 seconds), as much as possible, so it has time to cool down between usage. We try to over correct a bit when we use use the BT so as the bow falls off, the BT has more time to cool.

Subject: [Amel Yacht Owners] Bow-Truster overheat


 

Dear Forum

On my Amel-54 I discovered that the bow truster stops working after repeatingly use within 10-15 min timeframe.

I used the bow truster a bit more than usual when I practiced some manouvers first time; - and on a second occation when I had to manouver in a marina with a lot of windguests of 18+ kn and another chain over my Anker...

It stopped working and after a while (maybe 10 min.) it re-started & operated normaly. I know BT Is not made for constant use, - only few seconds at a time. Then wait and re-use another time.

Question from a beginner:

Does the bow truster has a termic fuse which is activated after some time of usage to save the motor from overheating? 

Does anyone know exactly how it works and if this can be adjusted because I think the BT on Wasabi switches of quite fast. Any ideas or other information?

Best regards

Alan, Were you able to buy that pump in a 24v . I looked at it on Amazon and only found it in 12v.
Thanks,

We replaced our bilge pump with a Johnson Power Viking 32 pump
Its max rated flow is 32 l/min.

Alan,

Great. I think this Johnson pump may be better than the Vetus that I have been recommending. I am am now recommending the Johnson because it much more widely available worldwide, including Amazon in the US.

The mounting holes are differently spaced than the original, so I made a mounting plate out of a nylon kitchen cutting board and drilled holes in the appropriate places, mounted the pump to the board loosely then mounted the whole assembly on the original bolts and tightened everything up.

Did you have any issues mounting it?

Alan,

That looks like a very good choice. As I am sure you realize, the mistake that some make is replacing the OEM bilge with a non-diaphragm pump that is incapable of taking some small solids.
