Well my problem is with the self bailing drain tubes in the floor. Unfortunately I can't just plug them from inside the boat because the lip that has fallen off is the side that comes out the bottom of the boat.

i dont have floor drains. previous owner removed them. the only thru hull below water is the baitwell drain. my fishbox drain has been glassed as well. i think you can get a flaring tool at west marine. good luck.
