The Ronco Plastics B180 holds 25 gallons in yet another distinct footprint - because in Ronco's world, capacity is the easy part and geometry is the product. Since 1974 the Tustin, California plant has answered odd compartments with new tooling rather than telling boat owners to modify the boat, and the B180 is one of the resulting shapes. Match the drawing below to your space; if it fits, you have found your tank.
It is a marine fresh water molding in FDA-compliant polyethylene, shipped at 83 lb with fittings installed per order - spin-welded or threaded, located to your marks. That per-order step is the practical magic of the line: your fill lands under your deck plate, your vent rises where your compartment rises, your pickup sits where 25 gallons actually drains on your hull. Print the drawing, mark it up, and confirm everything in the fitting planner on this page.
At capacity the B180 carries about 208 lb of water, so give it the standard respect: flat continuous support, snug restraint, low mounting. After that it is maintenance-free for the life of the boat. The rest of the 25 gallon class and every other size live at boat tanks; the full line is at the Ronco Plastics hub; the freight estimator quotes shipping by ZIP. OneSource Plastics is an authorized Ronco Plastics dealer.
