The factory installed cooler on this boat was a cool idea, really a huge space for more than enough cold storage than I would need but it warmed up quickly. Even on a cloudy 65* day it couldn't keep ice for more than a couple hours.
No pics here but I pulled out the bin they call a cooler and it's only about 3/16" fiberglass bin with a layer of carpet around it and a 3/4" drain that dumps in the bilge.
I installed a ball valve on the drain is rather keep the cold water in than have nothing.
I then got a roll of the bubble insulation and tape for about $30 and wrapped the bin. I then used a piece laid over the top of our items to insulate the top. (Sorry about that awful pic)
I used it like this for a couple months now with vast improvement over the original set up.
Today I decided to use the leftovers and lined the inside of the compartment around the bin with an additional layer of insulation.
I reinstalled the bin and added two layers of insulation to the bottom of the seat cushion over top. I'm expecting great results.
We do use cooler shock ice packs so I can't speak for straight ice but the beers stay cold all day.
