Has anyone replaced their 35 gallon holding tank on a Passage 42. If so, what materials and could you provide a supplier name and location. My holding tank has corroded to the condition of immediate replacement and would like to know of a supplier. Understand Ezell Industries provided these tanks but they have no specs.

P42 grey tank replacement
YES- did this about 3 years ago and did a detailed post on the job on this forum- you should be able to find it by searching under my name. I am on the road this weekend and dont have the info to hand, but i used a very helpful USA maker who had the correct Hunter drawing for this tank and were super helpful- I will post the details as soon as i get back Monday.
Getting the old Ezel out was quite a task, but i addressed this in my post. The one thing I would do different if i was to do this again is to increase the size of the breather outlet and hose to the thru hull ! I also paid the maker to fit a beckson inspection port in the top. Back to you Monday!

found it-
"I have just done this on my P42 in December 2010. Not such a bad job, but some tips;
1) to access tank (if you have not already done so) remove the sole ( floor) section in front of the 2 seater settee. 2) After all screws are removed slide it out on the RHS first- you need to do a bit of a twist to avoid jambing on the cabinet for the sink cupboard. Once floor panel is clear of this cabinet then simply pull back and it stand up- I left my floor section standing in the doorway to the front cabin, leaning against the door.
3) You now have access to your tank- centre hull cavity. Mine was installed with that horrible expanding foam- that was a *****! I found an ordinary wood hand saw worked fine to break the seal between tank and foam and hull and foam. I then cut small sections of foam out progresively using a hand held hacksaw blade until it was pretty much all out. Before you can remove the tank you should empty every last drop out- I used a wet dry vac- unpleasant job, but at least I avoided more unpleasant spills when moving out the tank. The breather hose in the rear is a bit tight to get to , but you must remove this before you can remove the tank.
I used a Ronco Plastic tank- off the shelf and a great product, from very helpful people and cheap! See my post on big boat forum head "P42 electric head upgrade" for more details.

Re: P42 grey tank replacement
Thanks for info. Can you provide name of US company that had specs of tank (phone or email). I have had floor up many times for other repairs but now need replace tank.

I just replaced mine after a "Major Failure" ! I got my replacement tank for Ronco-plastics.com. They already had the mold. Any other questions about replacing just ask.
I did give you the name- it is RONCO plastics- REALLY nice and very helpful people- they have the drawings and make a dimensionally perfect tank
When removing tank
I.e.,,, pump out tank
Then fill with water
Repeat 19 more times.
You might want to put in some tide detergent with your water flushes to get the sludge off the walls.
After your last pump out, here is an easy way to totally dry the inside of the tank
Get one of the oil extractor pumps which have a long inlet tube. Remove the tank sender on the top of the tank, (assuming you have one), and just suck all the remaining liquid out.
Then, remove hoses.
Lastly (VERY IMPORRANT) take short hose lengths (6 inches), and get wood rod which just fits the ID
Make up short "stopper tubes", and clamp onto all of the fittings.
Now, when you remove the tank, nothing will spill out into your interior.
This small precautionary measure is well worth it.
Now,,,
Once you have your tank out, this would be an excellent time to change out your old head hoses. You're going to end up doing this at some point. It's a lot easier with the tank out. Think about this..
Do literally about 20 full tank flushEs.

Hunter 42 waste tank
Thanks for the drawing. It is perfect. One question is the capacity states as 26 gallons on drawing and on the original it states 35 gallons. Is one incorrect. Not a problem as pumpout or macerator will take care of full tank. Just curious.
New P 42 holding tank
Ours was corroded so we removed it and had a new one copied from the original by an independent fabricator. We used heavy gauge alu and sealed the interior by coating it with a resin. So far so good.
Thanks for the feedback. regarding the Ronco tank the 24 gauge plastic is sufficient to prevent any smell from coming through the plastic walls.
