I seriously hate dealing with ice for fishing. I don't mind paying for it, I just hate carting it down the dock, loading it, and cleaning out the bags at the end of the day. In my currently uninsulated fish box it takes 300lbs of ice to get through an offshore trip. I am going to have the box insulated, and am contemplating adding an ice maker. If you have an onboard ice maker for your fish boxes, please share your insights. I am thinking about adding one. If you have and EI540 specifically, let me know how you like it. Thanks.
