Gday guys is anyone using a portable fridge/freezer as a freezer on there boat? I have set mine up as a freezer at -15 degrees .

It seems currently it runs most of the time and possibly shutting down for only about 5 to 10 minutes in every hour. It is currently empty it will be interesting to fill it and see what changes that makes. It's drawing 3.5 amps

Also I thought I might fill it with a few casks of water see if it can make solid blocks of ice I could then put into the fridge at nights and perhaps switch the fridge of at night times?

any experience much appreciated.
