I also installed a Nova Kool icebox conversion fridge on my Hunter 35.5 and would recommend it. The unit draws just over 3 amps and averages approx 2 amps per hour depending on the usage and the outside air temperature. (the average amperage will be variable depending on the size and insulation of your icebox and whether you want to use it as a freezer or a fridge) In the past I have found tech support from Nova Kool to be very good and parts are easy to get.
