One hundred gallons, no fittings, no compromises: the B249 is Ronco's century-mark marine water molding, shipped blank so the plumbing serves your boat instead of the other way around. At this capacity you are provisioning for real passages - day after day of galley, washdown, and crew water without touching a dock hose.
The blank arrives ready for your layout. Print the drawing below, mark fill, vent, pickup, and any inspection access where your installation wants them, and use the on-page fitting planner to spec spin-weld or threaded fittings; Ronco installs every one to your marks before shipping. Fresh-fitted, the food-grade polyethylene is proper potable material, and the B-series dual-role design means the same molding can be ordered as a large gray or black holding tank instead.
Plan the structure first: 117 lb empty, about 834 lb full. Nearly half a ton of water must sit low, centered, and on a platform tied into the hull or chassis, not on stringers that happen to be nearby. It ships as freight - run your ZIP through the freight cost estimator early. Molded in Tustin, California since 1974; see the neighboring capacities in our boat tank category or the complete line on the Ronco Plastics hub. OneSource Plastics is an authorized Ronco Plastics dealer.
