Not sure if mines the same way, but I noticed last year that I also had some water under the floor up front. When working on the engine and draining the water in the bilge, the water would drain backwards thru the 2 lowest drains. Only way I could get rid of it was to get the front WAY high. (Parking up hill,......trailer jack won't go high enough) Also removed the inspection caps up front and ran a fan blowing towards the openings for a week drying it out.

I now have rubber plugs in those 2 drains in the engine compartment to prevent it from back flowing again. Dry as can be this summer. 'course if your boat sits outside in the rain, the plugs may not be a good idea.

I have the same water problem in the area under the step. I have red carpet and the water appears red but the floor or potty area never seems wet.

But I just wanted to mention: Don't put bilge cleaner in there because the automatic switch likes the soap and just keeps running and running. I had to flush it out for a 1/2 hour to get it to stop.

Ive always parked any boat Ive owned sloping towards the back for drainage. My driveway slopes toward the road so I bought a great big jackstand and still have to put two 6x6 blocks of wood underneath the jackstand to get the trailer off level. This is way higher than the tounge jack can go so I had to buy a jack all in order to get the trailer up high enough. 3rd boat Ive used this setup on so its ok. I also put a stick on level gauge on the trailer tonge that RVs use , that works well also.
One thing that had me puzzuled for awhile was all of a sudden I was getting a whole bunch of water in the V berth floor while in storage in the driveway. It turned out I had started to open the flip up top section of the 3 piece cabin door for ventilation. With that open the water just pours down past and into the cabin floor. Closed the top and left the swing out doors open, no more water in the cabin. ...........Doug
