Take a quick glance into the engine compartments of the finest top quality boats today and you’ll find Gil battery boxes. Hardin Marine has taken over production from Gil on these battery boxes. You see this is the most imitated and copied battery box today. The problem for the imitators is they don’t use Almag 535 castings. Almag 535 castings are virtually twice as strong as the copy battery boxes made from traditional 356 aluminum.
