The Ronco Plastics B154 is the second of Ronco's 70 gallon marine fresh water moldings, and the existence of a second one is the point: at maximum capacity, compartment shape is the constraint, so Ronco tools more than one way to package 70 gallons. This shell ships at 97 lb - the lighter of the big pair - and the drawing below shows the exact geometry to check against your space before committing.
Seventy gallons rewards deliberate plumbing. Ronco installs fittings per order, spin-welded or threaded at the positions you specify, which on a tank this large means you can put the pickup where the last gallons actually pool, split fills or add inspection access where maintenance demands, and route the vent for real-world heel and trim. Mark the printed drawing, then confirm everything in the fitting planner on this page.
Full, the B154 holds about 584 lb of water - 8.34 lb per gallon compounds quickly at this size - so treat the installation as structural work: continuous bottom support, robust hold-downs, weight placed low. The FDA-compliant polyethylene will outlast the boat's next several owners; Ronco has molded it in Tustin, California since 1974. See the rest of the marine range at boat tanks, everything Ronco at the hub page, and shipping numbers at the freight estimator. OneSource Plastics is an authorized Ronco Plastics dealer.
