Water in Hull - Any info on the 240SSi hull?

Recommended Posts

So I bought my 2000 240SSi last September & hoped I bought a great boat. One owner, service by the dealer, rack kept under cover... Just finally getting into some of the nitty gritty on the boat & finding things yo never want to see. Water in parts of the hull! The port side of the boat appears to be really dry, but found water under the gas tank & inside the starboard side floor. This is how I found it. Any suggestions or info on how these hulls are built is appreciated.

1) Removed the bilge pump from the small ledge in front of the gas tank. When I took out one if the screws water started coming out of the hole. I drilled a 1 1/2" hole and saw standing water. Using a shop vac I sucked out must of the water. It appears that the prior owner installed a drain in the ski locker that drained straight into this area?!? This year & model boat didn't come with a drain in the ski locker did it? The hole definitely looks like the work of a paddle bit. Plan for this area is to remove the fuel tank at the end of season here, cut an access hole (probably 12" x 12" or so) to better assess any damage, dry out, repair and re-fiberglass.

2) Removed the gas tank access cover to replace the fuel pick up & fuel as preventive maintenance since I just had to replace the electric fuel pump. Again water out of screw hole... ughh! (Previously I removed the carpeted piece or plywood between the drivers seat and storage area in the bow. I did notice some water in these 4 holes. I blew these dry & used 5200 when I replaced).

(Previously I removed the carpeted piece of plywood between the drivers seat and storage area in the bow. I did notice some water in these 4 holes. I blew these dry & used 5200 when I replaced). To invetigate some, I removed the drivers seat, no caulking. There was a 1" plastic plug under the seat base that appears it leads to a foam filled cavity, soaked. I drilled a 2" hole under the seat base & found wet plywood. Under the bottom layer of fiberglass the foam was dry (finally a break). I poked the screw driver through the foam to the 1" hole and found it was all dry in between. Must be decent quality closed cell foam. I still have wet plywood between 2 layers of glass. Not sure exactly how it got in & I'll continue to investigate. I'm sure the hole under the drivers seat, the 4 screws in between the drivers area and storage area that were loose are some of the areas. Any ideas on this area are appreciate since there is no access.

Sorry to hear your unfortunate findings. You will now start on a long journey of discovery.

Was the boat stored outside ? on a trailer ? Try to eliminate rain as a cause. My Sunesta does not have limber holes for all the compartments under the "Floor" and they trap water. Next , sit it in the water after completly drying the bilge. Does it take on water?

Water is a problem that keeps popping up on Chaps. Do A search on the forum. Some of it is unpleasant, like the delamination picture.

Can you post any pictures of what you're describing? I looked in the parts list section, but couldn't find one that was for your boat. I can't picture the layout or design of the hull and the areas you're describing. I'm wondering if you have water within the laminate (in the coring) or in sealed compartments within the hull. Either outcome would mean a different kind of repair.

I'm with Joe, Pictures would help with your description since we both own a different model.

"removed the acess plate for fuel tank .. water came out of screw holes". ? I have a deck plate for access. I assume you mean the floor ?. you mention that the helm seat was not sealed. Could be source of water getting into plywood..Chap seems to have an aversion to using sealant.

Water out of the Bilge pump pad probably again from installing it without sealant. The holes soaked up water because they are always under water. A flow of water is different.

Removing the fuel tank is extreme. Find the source of water. I have a ragged drain hole in the ski locker floor at the fuel tank bulkhead. I can see water because the hull is relatively flat in this area and does not drain. With my weight added, it causes the water to drain to the back of the boat under the fuel tank and to the engine compartment.

Find the source of the water, then repair any damage. Otherwise you aill be fixing it again.
