Over the last 25 years, there has been a dramatic shift in the types of refrigeration systems carried aboard cruising boats.  Today, 12 volt systems prevail, but the systems most often installed up to the late 90’s were driven by the main engine.  Engine drive refrigerators function just like the air-conditioner in your car.  A belt driven compressor forces a refrigerant gas through a typical vapor-compression cycle.  Though it’s often one of the less understood onboard systems for boat owners, these engine driven systems only consist of a few key components.  A compressor with a clutch activated by an electric...

Gone is the mess of spider web battery cables and...
