Complete your Frigoboat installtion with the extra components that may be necessary for your boat - precharged extentions, compressor mounting bracket, or a Capri 35/50 air ducting kit.
Every boat should have a spare parts kit. Find those components here - spare zincs and zinc screws; spare electronic control module for when elec-trickery foils your system, but the control module sacrifices itself to save the major components.
Or perhaps you just need disposable ice cube bags, new light bulbs, ora circulating fan to gently move the air from the bottom crevice of your ice box to alleviate those too-cold-spots often found in custom shaped boxes.
