Re: Raw Water Manifold Failure - A54
Last paragraph Porter’s Email: attached is the part.
April/May 2018 it broke off completely on AMELIT; this is the replacement part I got from AMEL.
I noticed the new unit “sweating” & oxidizing rather quickly; it almost looked like 2 different metals were used. In July/August 2019, in VANUATU, checking & prepping the boat for the trip to the SOLOMONS, my local mechanic Matthieu & I decided to remove this unit completely and replace with a plastic (PVC???) self built unit which has been doing great with no “sweating” at all.
When I asked Thierry (AMEL SAV) this was his reply:
To answer your question this manifold is custom made by Amel . The welding between brass fitting and copper pipe is carefully done and there is no risk of leakage.
I have also been planning to redo everything along the A50/60 concept with individual shut off valves for each downstream line.

I am stuck & bored ☹ and have been cruising on my motorcycle (March/April) all over BAJA CALIFORNIA 😊 😊 and since June in USA via magnificient State & National Parks on my way to ANNAPOLIS boatshow 😊
AMELIT is in storage on the hard in COOMERA (near BRISBANE) QLD AUSTRALIA and now watched by fellow AMEL owners Sue & Brian MITCHELL (SV LOLA)

This is indeed a serious issue.
We had the initial bronze manifold on IBIS. Looked horrible and so when we ordered our arch from Turkey had a stainless replacement manifold constructed. About 2 years ago I changed the bronze one, with significant corrosion to the stainless replacement. One year after replacement upon inspection in NZ I found a small pit and a leak. It was in NZ that I had the resources to build a new manifold out of plastic. I had reservations about the material (plastic vs metal) but recall from an A55 that I believe the stock manifold is plastic on the A55. Encouraged by the chandlery in Opua I built a plastic one. It took a couple of days, a lot of measuring and 5200. I put in isolation valves. I think it is far better than the original. I’d encourage any others who have the resources of a nearby good plumbing chandlery to think about it. One of the very cool parts of the A55 is the ability to isolate and turn of seawater to specific downstream applications. (Don’t have to turn off the refrigerator to work on the AC pump)
I think we’re a lot safer now. I repaired the stainless manifold and keep as a spare, but would be lothe to return to it.
Keep in mind there is another smaller manifold (of which we also keep a spare) starbord of the seachest that distributes to the main engine, and then to the distribution manifold via a (formerly iffy) looking hose. That manifold could also easily fail. Amel has replacements.
