Fixing the 350 fridge, etc
Stu- I echo Tim's recommendation. The Catalina 350 International Assoc. website that he provided a link for has a lot of information about the refrigeration system and various improvements that owners have made. See the "Forums & Discussion" there. You will also find that, despite the refrigerator, most owners love their 350's and would not trade them.A few people seem to have no trouble with their frig's at all. Almost everyone has at least a high power draw, and some seem to be unable to obtain reasonably low temps, especially if they are based in the warmer climes. Mine (in the Chesapeake) stays pretty cold, but the compressor runs constantly to do it. The basic problem seems to be that the refrig. and freezer are very large but have only about 2" of insulation around most sides. Some units have open gaps where the box joins with the counter top, but mine didn't.Here are some of the things that owners have done, beyond testing for proper refrigerant level:1) Seal gaps at box/counter joint.2) Replace insulation in hatches and door (I've been told that Catalina will send upgraded insulation for these on request).3) Add a second gasket seal to the each hatch and door.4) Add an Adler-Barbour ventilation duct kit or booster power duct kit to move hot air out of the boat and prevent recylcing of hot air over the condensor.5) Add more holes in the partition between the freezer compartment and the frig compartment to allow more infiltration of cold air to the frig side.Most 350 owners (and owners of many other models)have added an engine cranking battery so that both of the 4D's can be used for the house. This makes power draw less of an issue for weekenders, but longer term cruisers will still have to find a way to replace that power periodically. I just completed adding a Group 24 cranking battery under the port settee and it was rather easy. Total cost, including custom-made 2/0 cables was less than $300. (As a side note, I got an estimate from a local electronics shop to have this done, and it came to $1700, including $700 for cable and 8 hours of labor at $95 per hour! I'm no expert, and it took me less than 3 hours.)GaryEven Keel II
