I have tried this all summer and seems to work great. I bought a couple of the foam floor mats from Wal-Mart , I measured my cooler lid in my boat and cut the foam mat and lined the inside top of it with the piece I cut out and the ice in cooler seems to not melt near as fast as without it. Also, I measured a piece and put it in the lid of my live well and it helped also , along with not bringing in any new water. I fill livewell in the morning when water is coolest, when i catch a couple of fish i put in at least a frozen pint bottle of water and keep the recirculator running, I don't put in any more water during the day. I keep swapping out the ice bottles throughout the day. I have not lost any fish doing this all summer. Must be working. Just thought this tip would help somebody. Oh, by the way I used contact cement to secure foam to lids.
