This is a common problem on C-25s and there have been many threads dealing with it on this forum. Do a search in the box at the left for "ICEBOX" and you should be rewarded with many possible causes and solutions. In the mean time depending on the model year C-25 that you have it could be a check valve failure or blockage in the line. The check valve (if your boat has one) should be located in the drain hose near the thru-hull valve. if it is a blockage in the line caused by a foreign object or and air bubble it can sometimes be blown out with a small plunger or a short blast from a compressed air horn applied to the sink drain.
I assume you mean th eIce box will no longer drain...
I also assume that you have disconnected the drain from the bottom of the icebox and poked around with a wire.
Does the Galley sink still drain? If so the blockage is between the icebox and the Y connector. Disconnect the Y connector and see if you can remove the blockage. If not, replace the hose.
If both the galley sink and Ice box are not draining, then the blockage is likely below the Y connection. disconnect the lower portion of the hose and see if you can remove the blockage. Also apply compressed air and see if bubbles come up from the side of the boat. Once you see bubbles, you have a drain.
If no bubbles, close the seacock, and replace the lower section of hose. If that still doesn't work, take a look at the outside of the seacock and see if something has grown over it creating a blockage.
The drain on our boat was clogged with sand when I picked it up in Ct, it was just a matter of clearing it up, the flexible hose has a tendency to flatten itself which does not help matters. If the sink is clogged also it could be the valve, I would not touch the valve unless the boat is out of the water, though. My two cents. Michel
Most of us have stopped up the drain with a rubber stopper and use the "cooler" for storage. Get a good ice chest and use it for cold storage: bigger, better insulated, and portable.
I plugged the drain in the bottom of the cooler because water from the sink was backing up into it and making mildew.
I used an old wine cork that I whittled into a taper to plug it.
I also placed a piece of crisscross plastic from an old drop-ceiling fluorescent panel to raise my items just above the floor of the cooler to keep them dry.
I use a large gallon zip-lock bag to store the ice, so that when it melts, I don't get a bunch of water on the bottom or in my food.
I also bought a 3.5 day Igloo cooler and use the same technique. Inside the bag, the ice water stays contained. I usually double the bags to prevent seepage.
No more drain needed because there's no more water.
I've run a straight shot from the sink drain to the seacock, and clean it out regularly.
