I had Bass Tracker TX17 (riveted hull) with exact same problem. I could easily pump out the seepage when fishing but when I left it tied to the houseboat at Lake Powell I had to get up in the middle of the night to pump it out or it would be way above the floor boards or worse in the morning. That's when I said enough. I didn't want to pull the floor out either so I crawled under it and found the seam where it was leaking. Was pretty easy to spot because the rivets were stretched to the point that they were actually loose in one area. I decided to try sealing it from the outside so from under the boat still on the trailer I put a nice bead of 3M 5200 along that area and let it cure. It didn't eliminate the entire problem but it slowed it way down. I could easily leave it on the water all night after that and only have a few gallons to pump the morning instead of 200 gallons like before. That 3M 5200 is pretty good stuff and even though it was right on the bottom of the hull, it never came off and lasted several years until I sold the boat.
