Re: Change of black water valve Amel 54

Dear Arno,


Well I just called Amel and he said that does not matter if bronze or stainless as far as the valve is connected to the ground cable.


I am using stainless valve in my company and one particular design might be interesting because once it is connected to the tube and the pipe laminated in the hull it will be very easy to change the central part by removing 4 bolts only.


Here the link:


I will let you know if easy or not removing the bow thruster.

Hi Alain,

I'm not sure about the stainless as the pipe that is laminated in the hull is probably bronze, I'm not sure. In theory the bonding cable to the anodes should protect the assembly but  it is quite the distance to the anodes. I think I would stick to bronze if available but that is more driven by ignorance then anything else.

When I removed the old valve I first removed the hose clamps but I did not try to get the hose off. There is very little room and barb that sits on the valve will rotate inside the hose when rotating the valve. Once the valve is unscrewed it is a bit easier too get the hose off.

I have not yet had the pleasure of removing the bowthruster That is on the list for next year hopefully. Or maybe for the hurricane season when the boat will be stored in Curacao.
