I tried the silicone. It's too hard to seal properly.
Get some of that very thin weatherstripping tape. The white dense foam type, not the lighter gray stuff. I used silicone to seal around the hoses (I have one of those medical therapeutic units with the hoses coming between the cover and cooler). I put the water and ice in (to the maximum level), close the lid, seal with duct tape while I sit or kneel on the cover, then clamp the cover with the handle. I also tighten the strap quite a bit and I have zero leakage. Buy some of the cheap duct tape so you don't use the good stuff on it. The cheap stuff works fine for this.
