Bill, Thanks, I should have looked at your book first. My boat is on a my mooring where we live ,it has not been in a slip more than a dozen days in 16 years. 
Thanks Again,

Pat,

Normally, you will find a large yellow/green wire bolted to either the C-Drive cross-bar or to the engine iron frame. Since everything is electrically connected the bonding wire protects all that is bolted together down to the propeller.

See the use of a test lamp to check for a Positive or Negative Start Battery leak in the attached page from my Amel Book.
The fact that the zincs are dissolving is good. This means that the zinc anodes are protecting metal superior to zinc. Possibly your zincs are depleting because of a nearby boat or dock which is wired incorrectly or a nearby metal boat that is not correctly protected.

Anyway, my 2 cents.

The reason you should not is that your SM tank is made of 316 stainless steel. You will get dissimilar metal corrosion where the stick touches the tank...worse case is that the corrosion will penetrate the tank.

The above is not true with later model tanks beginning with the 54 that are made of aluminum.

Re: D3-110 Starter Earthing Relay Part Number Request

I use a thick napkin that sort of stays in place. I just check it as I do the oil dip stick and general running checks.
Last year there were a few crystals. I decided to buy a new pump and kit. 
I fitted the new pump and serviced the old with new bearings and seals. Eventually the shaft will get a wear groove. One can buy a new shaft too, if required.

Re: Fuel Stick

Bill, Eric, I only have about 3 feet of the stick in two pcs. , the rest is in the tank ,but I cannot see it ,so no repair is possible. The hatch fell on it when I had it partially out ,my mistake. I do have a pcs. of flat pvc  11/2 " x 1/4" ,maybe I could use that . Since the tank is a regular shape ,I can use the piece I have to mark the increments of fuel level. It would be useful to know the length from bottom to full.

I have fuel diverter valve which sends new fuel through a Racor filter—Thanks Ian and Judy- through a pump and then into the tank. Zealous crewmembers have broken the stick by not removing it from the tank before turning the diverter valve.
It is an easy permanent fix on Kimbelite. Please send photos and possibly the stick can be repaired.

Re: Sliding ring seal of Calpeda pump

 

Martin,

If you are referring to the 12mm seal pictured below, yes, it is fairly standard. I bought several at a sidewalk shop in Penang, Malaysia. Just make sure it is made of stainless steel. Failure to replace the seal will ruin the motor as saltwater will enter the electric components.
image.png
Below is a Calpeda Pump motor ruined by saltwater because of a failed mechanical seal:
image.png

If you are referring to the "Sling Washer," its purpose is to try to mitigate saltwater from a leaking mechanical seal from getting into the pump motor and ruining it. The sling washer will mitigate some of the saltwater, but not all of it.

image.png

It is possible that you will not see or understand some of the tell-tale indications of a leaking mechanical seal because of what the sling washer does. It will throw the salwater away from the pump shaft. In the photo below, you will see a line of rust on the stainless steel freshwater accumulator tank. This line of rust got there because of the sling washer.

Lastly, here are the instructions for replacing the mechanical seal:

Re: Main hatch

Just some info on hatch retainers. Attached are photos of the hatch retaining system as installed by Amel  when  delivered to Joel Potter.
Pic #1 shows the door up and the lockers in the "unlock" position. 
Pic # 2 shows the elliptical lockers for the hatch. Up for unlock, down for locking.
Pic # 3 shows the release springs that disengage the wood bar  when lifted up. The springs are over the threaded rubber pieces that attach the ss shaft to the door. 
You simply lift the door with the handles  up the put the handles in the down position to lock. Reverse to open. 
The hinge in Pic #1 is to lift and remove the door as needed.(See Picture)

Re: Fuel Stick

Bill Kinney
 

Pat,

Do not forget there is nothing magic about a flat dipstick.  A piece of 1/2” PVC pipe would serve as well, and be easy to mark. On the pricier side, you can order a piece of stainless bar stock of appropriate width, thickness, and length from online metals.  It would be a lot more tedious to drill level marker holes in the SS, but if you left it mill finished instead of polished it would be easy to see the liquid level and could likely get away with just “dimples” to mark the levels.

On my old boat the diesel dipstick was a wood dowel. I used wraps of wire to indicate 10 gallon divisions, and small notches to show finer divisions. Maybe a bit “ghetto” but it worked a treat for 15 years.

Re: Main hatch

Hi Nick 
Already done:)  Works like I experienced on your DarNico.
Perfect and simple. Once it is set at the right tension you do not need to touch or turn the black nuts again.
(Maybe once in a  while a little added tension)

Just like Henry Amel intended it I would think.
No difficult systems. I just needed to sharpen the edges of the retaining groove as they flattened a bit over the years.

A little silicon spray and the varnish doesn't scratch:)

Thanks for the reminder

Re: Fuel Stick

 

Pat,

Sorry, I did not answer your question. What happens inside the macerator pump when the seal starts leaking is saltwater gets into the motor wiring and inside the motor case. 

With the electric toilet Flush/Empty switches in the OFF position, the negative of the 24v house bank is still connected to the motor. Only the positive wire is switched with the switches. The saltwater creates continuity between the negative and the motor case. The bonding wire is connected to the motor case. Saltwater bridges the bonding to the negative side of the house bank and you have a negative leak.

You would only have a positive leak when the motor is energized by the switch.

You may remember that I have been eating up my zincs faster than normal. You have said that the electric toilets are a source of electrical leak. Does that occur only when you run it ,have the switch on? Maybe I should email yo direct or put it a new thread.

The reason you should not is that your SM tank is made of 316 stainless steel. You will get dissimilar metal corrosion where the stick touches the tank...worse case is that the corrosion will penetrate the tank.

The above is not true with later model tanks beginning with the 54 that are made of aluminum.

Danny ,I wish I could ,but it broke into many pieces , some still in the tank. I hope they won't be a problem down the road.

Hi Pat, I am sure it is possible to repair the fuel dip sick. I haven't done it but a wrap of fiberglass cloth and resin should do it with good cleaning beforehand eg with acetone.
Kind Regards

Re: Fuel Stick

Bill, Yes that is what I remember you said, but I was wondering if that leak only occurred while being operated. I assume that the electric current travels thru the water in the intake hose to the sea and would be broken once the hose was empty of sea water ?? I wish my boat came with the Mass. Is there somewhere in the file section that explains how to detect a leak using a volt meter. I am not sure I have done it correctly in the past.
Thanks,
Pat

Pat,

I probably did not make myself clear regarding the electric toilets. I later model SMs and all models from the 54 onward, Amel installed a current leak detector (MASS). It is a small toggle switch and LED which will test for a connection between the house bank positive and Bonding as well as the house bank negative and bonding.

When a failure is indicated by the LED, it is almost always caused by a failed seal on the macerator pump on the toilet, unless of course if someone has made some change or addition to the wiring anywhere on the boat.

This is what it looks like on a 54:

Snippet from my book:

In your case without the Amel-designed testing device, I think you can do this to see if you have a leak...finding it will be another chapter...let me know.

As for the water pump located above the 12v alternator. There is a shelf or drip tray under the raw water pump. I place a dark napkin under the pump on this tray. When, not if, the pump starts to drip you will see white salt crystals on the napkin. Time to change the pump seals.
In my experience it always happens gradually. Only if you ignore the drip will the alternator get salty wet..
