Alas, most of our problems have been caused by 'professionals' and

If you really have to do it yourself I'd recomend that you start with
a copy of Nigel Calder's book: "Refrigeration for Pleasureboats:
Installation, Maintenance and Repair"

You can get it from Amazon.com

You will also need a set of pressure guages, vacuum pump, leak
detector, temperature guages, IR temperature gun, small vacuum cleaner
and a few other specialized tools/supplys.

Most of the tools and supplys are available from Grainger:
