This past weekend my family and I went out on our boat for the first time in a month. We keep it in a lift year round. After we were done on Saturday night we tied off and left it in the water. The next day there was 2ft of standing water from the bilge through to the cabin. Luckily we got there when we did. The batteries were turned off so the bilge pump was not running. I lifted the boat out of the water and pumped the boat out and checked the engine. The engine was fine though 2 more inches and we would have had serious problems. Once pumped out, I put the boat back in the water, started the engine and checked all hoses, no leaks. I turned the engine off and took a fairly bright light into the engine chamber and couldn't see any leaks. We took the boat out all day with no problems. We even tied off with some other boats for about 4 hours with no leaks. What in the hell happened? Has anyone had this problem? Any ideas on what it could be?
