Re: Fresh water tank
Not sure where you will find an used one, use to be a salvage yard in GA. If your tank is plastic you can have it welded or try Flex Seal tape maybe, Or just replace it with w new tank! Good Luck!!Mike

Re: Fresh water tank
I think you will be better off to just get a new tank made, there are plastic places that can do this kind of work to order, check around your area. This way perhaps a larger tank if it will fit.....Graham wrote: May 10th, 2026, 1:55 pm I have a 1977 carver mariner 28 foot and my fresh water tank leaks. can it be repaired or is there a pac to purchase one, or is there a used on available?

Yes they can be repaired but.....I have tried getting old plastic tanks welded, did not work for splits/cracks around threaded fitting parts. There will always be some doubt down the road with a repaired part especially on old plastic, IMO.
FWIW.....The above is just my opinion.

Re: Fresh water tank
Do you know WHERE it's leaking yet? Could be just one of the fittings cracked over the winter and needs to be replaced.
If you do end up needing a tank, greatlakesskipper has tons of them of various sizes. You likely won't find the exact tank, but if you take measurements of where it has to fit, you could likely find one on that site. You could even go a bit larger or smaller depending on the space. And they're great prices compared to buying a brand new or a custom one to your same dimensions.
