2013 Axis A20 and A22 wakeboard boats will have Malibu's new Hi Flo ballast system. By upgrading to the 1100pgh Shurflo Piranha Pumps with 1-1/8" hose the standard ballast system will have decreased fill and drain times. The ballast system speed has always been the big complaint with Axis Owners since 2009. To facilitate faster draining Axis has changed how the hoses are routed and increased the size of fittings in the ballast tanks making the Plug N Play system more functional.
