Last time I used the igloo 48 marine cooler but no drain so I had to drill it out. but I don’t think there is as much support. when I tighten up my drain it doesn’t seem to be as tight as when the cooler had a drain. I use a boiler drain on the outside. I make a plastic nut with a washer for the inside. I have seen the 48 igloo at sports authority. I bought the 48 marine at Big lots $30.00
