Hi All. Does anyone know it the icebox/refrigerator compartment on the LF39 is insulated. I noticed today that my freezer plates are not freezing like they used to. I added some Freon about a month ago, working great. I'm thinking after 20+ years it is time for a new unit. Before installing a new unit, keel cooled this time, I want to insulate the box first. I'm thinking of using a pour in expanding foam. My carpentry skills are severely lacking. Douglas Mountjoy 1988 C&C LF 39 Mexico at large 1984 Sabre 34 Port Orchard, WA

I did that with spray in foam on my 1981 40’. There seemed to be very little insulation. I was very careful to spray and wait until it settled. That stuff can exert some tremendous pressures and crack things… From: Doug Mountjoy via CnC-List <cnc-list@cnc-list.com> Sent: Thursday, March 28, 2024 3:37 PM To: cnc-list@cnc-list.com Cc: Doug Mountjoy <svrebeccaleah@gmail.com> Subject: Stus-List Fridge insulation Hi All.

Doug, I am guessing that the LF39 icebox was not much better than the ones on the LF38s which were terrible. Six years ago I installed Isotherm 3751 ASU SP Water Cooled Refrigeration system, gutted and rebuilt the insulated box. I put in a divider to have a small freezer section which works great and the main box keep nice and chilly. In August, it consumes about 24 AH per day whereas currently it consumes about 13 AH. The Isotherm system uses a water cooled heat exchange thru-hull which is like a keel cooler, but in my opinion better. Here is the link to my blog which contains mostly photos. I intended to write it up better, but never got around to. https://svjohannarose.blogspot.com/2018/01/icebox-upgrade-to-refrigeration.html - Paul E. 1981 C&C Landfall 38 S/V Johanna Rose Fort Walton Beach, FL http://svjohannarose.blogspot.com/ > On Mar 28, 2024, at 3:37 PM, Doug Mountjoy via CnC-List <cnc-list@cnc-list.com> wrote: > > Hi All. > Does anyone know it the icebox/refrigerator compartment on the LF39 is insulated.
