Re: A55: fresh water pump system
Paul Stascavage
Stuart,
Welcome to the forum my good friend. You will find a wealth of information here as well as some incredibly nice, knowledgeable, and helpful people. Just an FYI. It is best if you include your boat name, model, hull number and location below your signature line. This information will assist those who respond as there are variations among models and hull numbers. Additionally, knowing your location someone can often suggest services of suppliers or contractors in your area. All the Best, Paul Stascavage S/V Rita Kathryn SM #466 RitaKathryn.com Currently Cruising Bahamas

Re: A55: fresh water pump system
Joerg Esdorn
Stuart, I would try the following if the pump runs continuously. The cause is likely a lack of pressure in the Accumulator tank. At the tank, there is a blue cover which you can remove and where you can hook up a bicycle pump. Turn off the pump and pump it up so the pressure shown on the meter is 2 bar. See pic. I hope this helps!

Our 1993 Super Maramu has the same fix except that the battens are white. It looks like it was tedious process to fit but the result is perfectly acceptable. I am not near the boat at the moment so I can't post a photo.

Re: Bonding and grounding on Maramu
Hi Matt,
I don't think that's right. Our ICOM setup, setup according to the installation instructions, has a heavy green yellow/wire from the SSB ground connection to the AT130 tuner. Then there is a heavy green/yellow wire from the AT130 tuner to the bolt connection in the lazarette which has copper tape connecting that bolt to the sintered bronze plates on the skeg. If you don't connect it like this , where does the ground for the SSB transmitter go? ... certainly NOT to the bonding system. In our ICOM SSB, the transmitter ground is internally connected to the 12V negative supply line, hence the need for an isolated power supply so that there is no connection between ground and 24V negative, which would compromise the bonding system via the seawater path between the sintered bronze plate and the anodes.

Re: Headliner fix
Mike Longcor (SV Trilogy)
Hi Chip,
Trilogy (1990 SM23) needed a fix for its failing headliner when I bought her in November 2017. First attempt was to remove all the old, toxic junk between the vinyl and fiberglass. It was a brutal task and a serious health risk as Joel makes clear. We tried 3M headliner adhesive spray hoping it would stick with the disintegrating foam layer removed. We tried this in just the bow first. It didn't last more than a month. The solution we ended up with was 1.25" wide x 0.25" thick strips of wood screwed into the ceiling about 1 foot apart. The wood we found was from an old wooden boat (marine quality and a good color match after some new varnish). We used this solution everywhere and it's holding up very well. Only if you reach up and touch the vinyl can you tell it's not really attached. I hesitated doing this at first because I wanted an original look and didn't want to put all those screws into the boat. Looking back, I wish I skipped the torture experiment in the bow and went with the wood strips first. There are other ways to tackle this issue, but these strips saved us a lot of time and money. Stay safe! Cheers, Mike Longcor SV Trilogy SM23 Opua, NZ

Re: A55: fresh water pump system
Stuart, There could be several possible issues, but I suspect that if you are not losing water and only losing water pressure, there is a problem with the one-way valve on the freshwater pump. This valve is important to build pressure. When it is leaking, defective or blocked by debris, the pressure will not build and water pumped by the freshwater pump will return to the tank. The one-way valve is a brass fitting on the output of the freshwater pump. It looks like a simple brass connector, but inside is a valve. The photo below isn't your exact setup, but similar. I suggest finding the one-way valve and removing it for inspection. You did not say where you are located, but many plumbing shops will have this valve. Again, everything above is based on the fact that you dod not say that you are losing water and that the pump is running continuously with some pressure on an outlet close to the pump. There could be several other possibilities...the above is my guess based on what you wrote.

A55: fresh water pump system

Bill ,

Being a newcomer to the Amel Yacht Owners Group I am not sure yet how to post a question and so I hope you don’t mind uf I address it to you. We have a lack of pressure in the two bathrooms and the fresh water pump runs continuously except when turned off on tbe 24v board. There seems to be plenty of pressure on the transom shower. Might there be a filter in the pump or a pressure switch at fault? Stuart

Re: Bonding and grounding on Maramu
The SSB radio transmitter ground is different from the antenna tuner ground. They should not be in common.

Our ground for the SSB is connected to the tuner that is located as far aft on the starboard side of the boat as you can go. I think we have had some modifications to our boat in this area but ours sits behind a removable panel.

Re: Converting my Amel 54 to lithium batteries: what I did, what I like and what I don't like (after one year of full time live aboard use)
Jamie Wendell
And Scott, one more thing. Thanks for that suggestion about having a backup 12-volt starting battery. I have never had a problem, but as they say, never say never.
I might add that I will be trying to sell off my existing batteries, which are Firefly batteries. I installed them after my earlier 2016 battery compartment explosion, and they have been good. The problem I have found is that the voltage drops off and shuts down many of my critical systems (like refrigeration) and kills my pump. I probably have too much "stuff" to avoid that problem, and I also feel that it is critical that you equalize batteries in series to make 24 volts - I have been remiss there. And I do have solar panels (about 750 watts) and a wind generator. Anyone interested in 10 Fireflys? Jamie Phantom A54 #44

Jamie Wendell
Scott, a lot of great comments and thanks for being so detailed. That really helps us all out here in Amel land - learn from other's mistakes (er. success I mean)?
My approach is to do the breaker allocation thing as a test to see what runs and what doesn't before I "permanently" split the AC bus - just a matter of moving a few wires really, so no big deal. And you are right, I just read up on the Mastervolt USB issue, and I will be adding the converter as well, so that I can plug in my laptop to do the programming for the alternator. I just ordered all my parts through Battle Born - thanks to Bill Rouse for that assistance. My contractor and I are both going to be winners now!! Oh, and regarding the load issues, the good thing (to me) about having dual Multis is that I can always parallel them if I need the extra oomph. We shall see - all it would take is some bigger wires. Sounds easy, right? I will keep all informed as I get this Lithium deal installed and up and running. Best to you and Mia. Jamie Phantom A54 #44

Re: Bonding and grounding on Maramu
Hi Miles,
If your boat is like ours, which I assume it is...... On the skeg is a sintered bronze plate which is the ground for the SSB radio. The wire from that should end up in the nav station area and only be connected to the ground connection on the SSB.. This cable often has BLU written on it. This cable is only connected to the bonding system if there is no SSB. If you have an SSB connected to this cable, there should not be a connection from this cable to the bonding system. The bonding system is all the wires from metal items in connection with seawater connected together and eventually connected to the rudder shaft which is connected to the anodes on the rudder. So if you don't have an SSB, it seems correct. If you do, it isn't. Cheers Alan

Hmmm confused still. Which bit in the photos is the ssb grounding plate connection? I have 0 ohms when I test between the copper strap In the transom locker and the rudder post connectors so assumed these are all bonding ? Thanks again Miles

Re: Bonding and grounding on Maramu
You are seeing the grounding plate)cables for the SSB counterpoise. The copper strap in the bilge is the keel connection to the bonding system and zincs (assuming it is like the SM) which connects to the zincs via the rudder post. Kent SM 243 Kristy

Bonding and grounding on Maramu
smiles bernard
Hello folks
I’m just in the process of replacing the keel bolt bonding strap on my 1985 Maramu. It’s led to some head scratching re bonding and grounding and the wiring runs on these lovely boats. SeaLove has a copper ground plate on the skeg. I assume my radar is grounded to this. Perhaps also my furuno weatherfax etc Can anyone be kind enough to explain where the connection to the ground plate typically surfaces? Also to check my assumptions re the bonding system setup. . . . I think all bonding cables run onto a connection in the transom as per the photo attached It ‘looks’ like this copper plate is glasses into the hull and runs down the transom to surface near the rudder via the two tubes shown on the left in the photo below : For some reason this surfaces as 2 separate cables that then are both connected to the rudder stock, and hence the anode on the rudder : Does this bonding setup look about right ? Slightly confused as to why there are 2 cables here ? Many thanks in advance Miles Maramu 162

Re: Headliner fix
Chip Beaman
Joel,
WOW I knew there were health risks associated with the removal. Did not know it was that bad. Your first hand knowledge of this is very powerful, thank you for that response and warning. I will remember that always and pass it on. I am of the opinion that the plywood that was placed over the vynal to avoid/defer the removal is not a bad solution. I’m of equal opinion, at some point it must be addressed. I am guessing the replacement is not a cheap date. Thank you again for your response. Chip Future Amel Owner

Re: Headliner fix
amelforme
Here is some helpful information regarding the headliner with the foam backing. FIRST AND FOREMOST. THIS STUFF IS DEADLY POISONOUS AS IT IS MADE OF POLYURETHNE. IT TURNS INTO A FINE DUST AS IT DRIES OUT AND CRUMBLES. ONE NEEDS TO WEAR AN APPROPRIATE RESPIRATOR AND USE EYE PROTECTION AND PROTECTIVE CLOTHING TO PREVENT SEVERE HEALTH COMPLICATIONS. YEARS AGO, I WAS INVOLVED IN WORKING OUT A PROCESS TO REHANG THE FALLING VINYL AS MANY OF THE AMEL BOATS I WAS RESELLING HAD THIS CHALLENGE. ON THE VERY FIRST JOB AFTER TAKING DOWN THE HEADLINER, I GOT VERY ILL AND MY 65 YEAR OLD EXPERT YINYL HANGER ENDED UP IN THE HOSPITAL AND ALMOST DIED. I CANNOT OVEREMPHACIZE THE IMPORTANCE OF BEING EXTREMELY CAUTIOUS AND TAKE EVERY PRECAUGHTION TO NOT BREATHE OR IN ANYWAY INJEST IT OR GET IT IN YOUR EYES. I ENDED UP DOING THREE OR FOUR BOATS PERSONALLY WITH HELPERS ,AND SUPERVISED ANOTHER TWENTY OR SO BOATS OVER THE YEARS. Working during the hot and humid Florida summer wearing a respirator and a plastic full coverage overall suit was not anywhere near as uncomfortable as getting sick from this stuff. BE CAREFUL. As further caution, in the early days of polyurethane paint, the warnings on the cans said, " Do not use this product without a respirator and appropriate protective clothing. It will kill you." I remember asking the paint foreman at the yard I used in San Diego ( Kettenburg's , remember them? Condominiums are there now ) what was with that warning. He said the paint distributor told him a lot of the older paint sprayer specialists got very sick and died because they did not pay attention to a milder warning about 'serious health risks’ and the paint makers were tired of being sued. I am as serious as a heart attack, the dust from the poly foam will make you wish you had been more careful. I was sick for a month. I have written about this before on the Amel owners group site and there are several ways to accomplish a good and attractive repair. Here is the most important background information. Every Kirk, Sharki, Maramu, Mango, Santorin and Super Maramu built prior to about February 2006 had the polyurethane foam backing on the headliner. Boats built after that had an organic spun cotton/felt backing which does not deteriorate with thermal cycling that occurs with each sun up/sun down. I have yet to see any of the boats with the felt backing have anything more than minor problems with adhesion and it won’t try to kill you when you work with it like polyurethane will. Again, there are several ways to get a good repair, dependent on if the original vinyl hasn’t been ruined with attempts to re-hang it with glues that ‘melt’ it. If you must replace the vinyl, I would suggest cotton backed material as it does not deteriorate like most every kind of plastic foam will.
All The Best, Joel

Re: Headliner fix
The issue wasn't that they used foam. The issue was the type of foam and the process of adhering the foam to the vinyl. This is the reason that the problem doesn't exist in later Amel SMs. Best, CW Bill Rouse Amel Owners Yacht School +1 832-380-4970 | brouse@... 720 Winnie, Galveston Island, Texas 77550 www.AmelOwnersYachtSchool.com Yacht School Calendar: www.preparetocastoff.blogspot.com/p/calendar.html
