The Ronco Plastics B164 answers a specific refit problem: you need 20 gallons of fresh water and the compartment refuses every 20 gallon tank you have found so far. Ronco's answer for five decades has been more molds rather than more compromise - the Tustin, California plant has been cutting new marine tank tooling since 1974 - and the B164 is one of the shapes that came out of that stubbornness. The dimensioned drawing below settles in a minute whether it is the one your boat has been waiting for.
The molding is FDA-compliant polyethylene for potable service: seamless, taste-free, and permanently indifferent to salt air. It ships blank at 80 lb and gets its fittings installed per order - spin-welded or threaded, at the sizes and positions you specify. Print the drawing, place the fill under your deck plate, the vent on the rise, the pickup at the drain point, and put the plan through the fitting planner on this page.
Full, the B164 holds about 167 lb of water; give that mass a flat platform and firm restraint and it will never remind you it is there. If the outline is not your outline, keep looking through boat tanks - the point of the Ronco line is that one of them fits - or scan everything at the Ronco Plastics hub. Shipping quotes to your ZIP run through the freight estimator. OneSource Plastics is an authorized Ronco Plastics dealer.
