Mine is a 2002 C250 WK. Water intrudes into the battery compartment. I sealed both cockpit coaming compartments, resealed the motor mount and rudder mounts, sealed the opening where the battery cable for the engine exits... still, after a heavy rain, water shows up in the battery compartment.

What did I miss? Where did I miss? Any thoughts?

Rubber steering boot needs replacement?

Do you have cockpit speakers?

Bedding of perch seat stanchions?

Bedding of stern light?

In the past, some have indicated putting a chalk line on the inside hull surface and then after a rain, seeing where the chalk line has been disturbed.

On my CAT 25, I have very few leak type issues, nevertheless, occasionally I would see a little water in the bilge. I noticed a water stain that would appear sometimes after a rain at the bottom of the mast column. I have my boat in the water all year and did not want to take down the mast to inspect how that mast plate is through bolted, so......I bought some waterproof (clear) spray adhesive from Home depot and using the tube that came with the spray can, inserted it in where my halyard blocks are located at the bottom of the mast and gave a few sprays. No more water stains from the mast column and I have found that even with several big rain storms during the past year, I have no water collecting at all in the bilge !!

Our '95 C250 was one of the boats who encountered a similar problem.

" READ DANGER!! "

Water (in our case GASOLINE from an improperly closed 3 gallon tank gas cap while trailering the boat over a rough road) entered the fuel compartment, sloshed around and by dripping through the floor into the battery compartment below. From the battery compartment it ran into the aft compartment and soaked the aft berth cushions.

This is a serious problem and is extremely dangerous!!

One tiny static spark and the boat would have blown sky-high, myself included!!

Several C250 of the same vintage have reported this problem.

To remedy... remove the fuel compartment lid and all its contents. Clean the floor of the compartment thoroughly especially around the hollow edges.

Inspect the deck/sidewall fuel compartment connection and floor all around inside the entire compartment very carefully, (use a mirror if required and a spark-free light) most likely you'll see unsealed exposed fiberglass fibers or thinly glassed areas.

If required fill the fuel compartment with some water to test and to locate leaks inside the battery compartment.

In our case water/fuel entered alongside the inside of the walls/deck connection, pin holes and through a "thin spot", of the tanks floor. Sealing the hollow wall/floor connection with a gasoline resistant caulking is, after a drying out period, not a big job.

I've found water inside my battery locker in the aft also but it has not been much, never more than a cup. I was thinking it gets in when I launch because if she's been in the water awhile it stays dry.

Safe voyages,

Aha! I always wondered myself. Also, in this hot, dry, NE summer of ours, I noticed that there is a fair amount of condensation in the aft berth- enough to cause water to coat the underside of the cushions. I noticed that if I cracked open the forward hatch things seemed a lot drier when I came aboard. I now have resigned myself to pulling the starboard aft cushion out when I'm not aboard.

Checking the fuel compartment may be a big help. Thank you.

When I'm leaving the boat for awhile I (almost always) open the lockers for ventilation. Used to leave the clamp-on fan running also but I started wondering about it catching fire.
