Nineteen gallons in 27 x 15.25 x 12 inches: the B549 sits in the gap between the small day-boat tanks and the serious cruising sizes, which makes it the natural upgrade when a boat's original tank has become the thing that ends every trip early. It is proportioned like a sea bag - longer than wide, wider than tall - and settles into cockpit lockers and under-berth spaces that were never drawn with tankage in mind.
Ronco molds it as a dual-role B-series blank. Fresh configuration: supply fittings in FDA-approved potable polyethylene. Holding configuration: waste fittings, same molding. You set the role by what you order, and Ronco spin-welds or thread-installs the fittings at your marked locations before shipping. Print the drawing below, offer it up to the space, mark your ports, and finish in the fitting planner on this page.
Empty it is a 22 lb one-person lift; full it carries about 158 lb of water, a load that asks only for a flat supported base and a strap against surge. Molded in Tustin, California - Ronco has built marine tanks there since 1974.
Neighbors on either side of this size are in the boat tank category and RV water tanks; browse the whole family on the Ronco Plastics hub. OneSource Plastics is an authorized Ronco Plastics dealer.
