I was poking through a deck box in my cockpit and discovered that I own a 120/240v boost transformer that looks to be in near new condition. There is no switch to set various levels of boost so I assume it is designed to bring low voltage up to 240v and no more? It is labeled in the original name of the boat so I’m guessing that it is circa 1987. FWIW, the maker is still on business, but are not selling anything like what I have anymore. I will call them on Monday, but wondered if anyone knew another these units.

It is a portable unit that has cords to connect on the dock between the pedestal and my shore cord. It is labeled 120/240 VAC 50 AMP Boost Transformer Wards Marine Electric, Ft Lauderdale
