livewell removal in 20sf

[Blue197320]

has anyone with the in floor livewell removed it before? i think mine is leaking at the thru hull. i want to take it out and put a strainer down there and reseal the whole thing. i think it might be cabosiled to the floor and stringers? if thats the case that means its in there. it has been out before because around the perimeter of the well its got screws in it. ill post pics tomorrow when i see the boat.
