Tvsports86 0 Report post Posted June 13, 2017 Hi - I have a 2000 Monterey 242 Cruiser. For the last 2 summers, we've seen a small accumulation of water at the lowest point of the cabin. This water accumulates just outside of box where the cabin bilge is located. I've tested the bilge and it appears to be working. The box also just contains a small amount of water, not enough to trigger the float switch. Eventhough there is not much water in the box, it appears that some of the water is making its way out of the box and onto the carpet in the cabin. Thru my research it seems to be one of the below items (no particular order) 1. a hole in the bilge box thats allowing the water to seep out and onto the carpet. 2. Something with the head, I tried flushing the toilet and didn't notice any water accumulate. we also never use the sink or shower. 3. In the back of the bilge box there appears to be a tiny inlet where water can make it's way in. I suspect as backup bilge from the engine compartment. I can tell a small amount of water is coming in from this inlet, but would think the water should remain in the bilge box to trigger the float and then pump out. Not enough water is coming in to trigger the float switch but it is working. 4. There is a valve to fill the toilet, the seal into the box does appear to be fine and not leaking. I'm afraid something underneath that valve is leaking causing water to enter the cabin area. Has anyone dealt with this issue in the past. Any thoughts of what it might be?

wirth315 0 Report post Posted February 3, 2018 I had the same problem on my 1998 242 Cruiser... I finally figured it out. For me, it was the Window seals in the cabin windows. Mainly the bathroom window. It leaked on rainy days and allowed water to fill in the low point of hull outside the shower drain bilge box. After sealing both the windows in the cabin, my bow area hull remained dry. :-) Good luck if your still working on a solution. Also, check that your bow hook isn't leaking, as that may place water in that area as well. Share this post Link to post Share on other sites

Kris 0 Report post Posted August 12, 2020 Hi Tvsports86, Did you figure that out? I have the exact same problem and I’ve had the exact same suspicions that you did. I still have not got mine figured out, just a new issue for me now. Share this post Link to post Share on other sites
peter lally 0 Report post Posted August 12, 2021 I have a 98 Monterey 322 and have water in the lowest portion of the boat in the interior, it seems like water from the head, but I drained the tank and still got water. WE have had rain but this just came up, I am clueless. Share this post Link to post Share on other sites
