Sounds like you have a leak in the hull under the keel. If you don't want to pull up the floor to fix, maybe you can seal the keel from the outside and put a small drain plug in it. What do you mean by force water in?
I recently discovered West System Marine epoxy.
Coated all the new pieces of wood I installed including transom and floorboards with the standard epoxy.
Then I discovered how leaky this boat is and have been sealing the Hull with Gflex.
I guess I should have checked before I installed the floor.
My question is.
Can the keel drain hole force a lot of water in? Or is it designed in a way that it can’t? I put about a foot of water in the boat and it drips out pretty steady.
