Get all the manuals for all your equipment. Know who made the components. Most equipment you buy, from your engines to your watermakers are assembled of other manufactures equipment, not built by the name of the company on the item. When you need a replacement part, it can be quicker and always cheaper to buy from the manufacturer of it, or a major parts supplier such as Grainger, rather than the company who assembled the item. Be sure you have aboard a Grainger catalog, a West Marine catalog, and a Defender catalog.
