Ok Phil, here's the question........I have a Beneteau 45f5 with two top loading storage boxes. The OEM system is a Frigaboat with a "freezer" large enough to fit a can of sardines; which is one the right side. To the left is another area of the same size (6 cu.ft each side) that is intended for ice/block/bags. The divider between the two is stainless with the bottom corners 45ed so melted water will drain to the right so it can be pumped out by a foot pump to the sink. After 10 years, the system leaks an needs a recharge twice a year. I'd like to put a large upright freeze compartment on the left and refrigeration to the right side. what parts do I need to by form you to do the installation my self. you can reply on or off the site to Sail83494@aol.com
