The Ronco Plastics B141 carries 32 gallons of fresh water, which is real cruising range: washing up, cooking, and drinking for a crew across a long weekend without rationing. It ships as a blank molding - no fittings - because Ronco installs them per order, spin-welded or threaded at the locations you call out. On a water tank that matters more than it sounds: the fill needs to meet your deck fill drop, the vent needs to reach a high point, and the pickup needs to sit where the tank runs driest on your boat's trim, not on a factory's guess.
Molded in FDA-compliant polyethylene for potable service, the B141 is a one-piece shell with no seams to weep and nothing to corrode - the usual reason these tanks go into boats whose original metal tanks have finally let go. Print the drawing below, mark your fitting positions on it, and run through the fitting planner on this page so the tank shows up ready to plumb.
Budget the structure honestly. Dry, the tank ships at 91 lb; full, 32 gallons at 8.34 lb per gallon puts the contents alone at about 267 lb. That load wants a supported flat bottom and straps or cleats that hold it through a seaway. Ronco has built marine tanks in Tustin, California since 1974, and the B141 is one of the larger fresh water shapes in the line.
