Looking to replace my black water holding tank on 2001 Beneteau 331. Any suggestions on where to get hold of a suitable replacement?

To embellish on Kappa's answer, I believe they will customize tanks with regard to placement of fittings which is very useful. You can likely improve your installation. Forum member Peggy (The Head Mistress) has posted much about this and has a book published on head improvements. You would be well served to search past posts for her advice - and to buy the book.

You might wish to check with your local Beneteau dealer who should contact Beneteau USA. The 331 was built in Marion SC and the tanks were sourced in the USA.
When I had to change mine, Bénéteau shipped the exact tank.
You will drill the necessary holes for hose connecting. I would change all hoses at this time.

Thanks for the tip on The Head Mistress. Thanks Pierre, I did leave a message at our local Beneteau dealer last week but have not heard back.
I think everyone is busy at the boat show in Toronto.

Not the Beneteau folks. There was only 1 Beneteau 34 at the show. and a handful of small board boats. But if you were interested in a pontoon boat, a wake boat or an aluminum fishing boat, you'd be in heaven.

I have had good results obtaining replacement parts from Beneteau. Just have to realize that you will have to establish an account with Ward Richardson of Beneteau, in Marion, SC and a Beneteau dealer of your choice. The parts can be ordered from Beneteau in SC and are billed & paid through your dealer.
