Can not be too large!
In my book you can't have too much holding tank, I am going to increase tank capacity on my 33.5 and will sqeeze as much in as I can. Has anyone used the tee fitting normally used to go to a through hull, to link into an additional tank, and how did it work out?

Spec Sheet
When I bought mt '88, the spec sheet from the broker said 25 gallons. I don't think it's quite that large.

I'd be anxious .....
to find out how you get the tank out of the existing spot in the head... If I remember correctly the vanity is a 1 piece unit that does not look like you can wrestle out easily. Keep us posted...

Asked Question
I asked this question last week. The boat across from us is a 87 37. He has to remove the cabnit top and cut a hole in the top. He is having someone local make a new one. Cost is around $200. He is not on-line but maybe I can get him over to the boat to say what he did.

I own a 93 Passage 42 on which I replaced the holding tank last year. They are made for Hunter by Ezell Industries, Rt2, Box 72, 15030 Beach Rd., Perry, FL 32347 (850)578-2558 Mine holds 36 gallons. I doubled the wall thickness to .190 and had it specially coated inside for sanitary use. It cost me $275 plus $23.47 shipping charges. This tank is foamed into place. We chiseled out the old foam, removed the tank, installed the new one and re-foamed it in place. It's worked great since - no more septic smell throughout the boat. Be sure to use only the black sanitary hose which is odor-proof. Another lesson learned: if you are having trouble pumping out with your maserator pump, BE SURE that the "O" ring in your deck pumpout fitting is air tight. If it leaks air, you will burnout your maserator pump and still have a full tank. Our pump (an ITT unit) pumps at 12 GPM. So it should not take any longer that 3 minutes to pump out your tank. If you run it longer, ,you'll hurt the pump. BE SURE to seal the hoses to the tank well and double clamp them. Good luck.

Holding Tanks Removal
Funny you should mention this. I just finished removing my holding tank. The thing looked like a piece of swiss cheese. 1st. I removed mine by cutting a hole in the bulkhead betewwen the head and the main salon. If you measure correctly, you can cut the hole under the nav. station and it will not be seen once it is fixed. There is no lateral pressure at that spot, so you will not affect the sturctural rigidity of the boat. I had to cut the vent pipe off the tank to get it out, but that just means that the hole was a little small. 2nd. Hunter can send you a copy of the original specs for the tank. It is 15 gallons. There is a place in Bayville, NJ, Atlantic Coastal Welding (732.269.1088) I faxed them a copy of the spec and they gave me a quote of ~$245. for a new tank. I will be taking my old one to them in the next week or 2. Hope this helps. Jeff

A caveat regarding metal holding tanks
Urine is highly corrosive--which is why the aluminum tanks in older Hunters are failing, and why Hunter now specs plastic holding tanks (unfortunately they aren't the same size and shape as the old aluminum ones, so we can't offer identical replacements for 'em in plastic). Any aluminum holding tank will typically start to leak at a seam or a fitting within 2-5 years (not necessarily after it's installed--a lot of 'em older boats weren't used for the first 5-10 years...only starting to deteriorate after they began being used) so if you replace with another aluminum tank, doubling the wall thickness won't help much...but there is something else you can do to prolong the life of aluminum tank: have it lined with an epoxy coating. If the quotes you've gotten from Ezel and other metal fabricators don't include an epoxy liner, get another quote...if they can't line it, find a fabricator who can. You only want to do this job once every 20 years or so...metal reduces the odds of getting that much service out of a holding tank, but unlined metal, regardless of the wall thickness, guarantees you--or the next owner--will be pulling it out again for repair or replacement within 5 years.
