made one last trip before putting the boat up for winter time and had 5 trout in the chest. Flushed the motor and I put the icechest of fish in the boat as I swept tht floor of the carport. Forgot about it

4 months later I went to hook up the boat and grabbed the icechest out the boat and it was heavy. Thing still had the trout from 4 months ago in it, but it was a Yeti chest and the fish were still iced down and perfect
