Hello,

I have a 1994 Lund Fisherman 1800 that I bought used two years ago. The boat always seemed heavy in the water and I think I just found out why. I removed the center floor board to replace the fuel sending unit and heard water sloshing around in both of the adjacent chambers of the hull. I took the seat mounts off and saw that both of the chambers were full of water in the ~1? gap between the foam and sides. I looked all around for a drain hole or plug but these outboard chambers seem to be sealed on all sides (but not the top). Why isn?t there a drain? The side chambers will always be susceptible to water.

Can I drill a hole into the chambers and drain into the center chamber where the sump pump is?

Any suggestions?

Thanks for your help.

Welcome to iboats, it sounds like that foam is saturated, I'd take it all out and install new foam with areas for water to drain.

Is it sprayed-in foam or block?

I'm not sure how to tell if it is block or sprayed. I can only see the portions under the seat mounts. If it was sprayed, it would have had to shrink in order to leave the 1" gap. Removing and replacing sure sounds like a lot of work. Could I hook up a blower let it air out over a few days?

Yes, drill a connecting hole as low as possible, about 1'' diam. After draining and drying , smear 3M 4200 on all exposed wood in the holes. Find the source of the water.

Thank you very much for your advice.

The water is getting in through the opening at the stern. There is gap between the floor boards and the wall that leads to the transom...it's wide open. It seems to be the design intent, which is why I'm so confused that there isn't a drain. I guess I could fixture a peice of sheet metal and seal it in with silicone.

Thanks again.
