than would be done by shifting passengers and/or gear on-board. See more information on Surf
Gate later in this section.
The tanks are controlled by toggle switches at the dash.
Be sure to empty the ballast tanks prior loading the boat onto the trailer and removing the
boat from the water. Tanks MUST be empty prior to trailering the boat as the additional weight
can cause damage to the trailer, and tow vehicle; such imbalance on the trailer could aect safe-
ty, or overload the trailer and cause damage that is not covered under warranty.
Water in the ballast tanks should always be pumped out prior to
removing the boat from the water. Never tow the boat on a trailer with
water in the ballast tanks; residual water can cause an imbalance that
alters the amount of weight on the trailer tongue. Without the proper
weight percentage forward, the tongue can become unstable and cause loss of control of the trailer and
tow vehicle. Additionally, attempting to tow your boat without the ballast tanks and/or bags emptied
can overload the trailer and cause damage that is not covered under warranty.
Boats that are going to be stored for more than a couple of weeks or pre-
pared for winter, must have all of the water removed from the ballast tanks.
Failure to do so can result in damage that is not covered under warranty.
When emptying the ballast tanks, watch the outlets on both sides of the boat and aft,
depending on the model and number of outlets. (If you are uncertain, check with your authorized
Axis dealer for assistance in determining the bilge outlets as opposed to the ballast outlets.)
Ballast pumps will continue working as long as the controller is ON. Therefore, operators must
ensure that the pumps are turned OFF when the outlets show only a small amount of water is
coming out. Leaving the pumps ON will result in pump damage.
If the boat is equipped with optional Plug ’n Play, Malibu recommends rechecking that the
rear tanks are empty ve minutes after starting the drain process. This veries that no extra
water was left from Plug ’n Play and leaked into the hard tank.
Ballast pumps must be turned OFF after emptying the tanks. When
only a trickle of water is coming from the outlets, manually turn OFF
the ballast pumps, via the toggle switch. Allowing the ballast pumps to
continue operating when there is no water to be pumped will result in
the internal controls being permanently damaged, which is not covered under warranty.
Flushing the Ballast Tank System
These procedures have been developed to help prevent the spread of aquatic invasive
species, especially quagga and zebra mussels that attach and infest inside ski boat ballast tank
systems. Flushing the system with hot water (150°F or greater) kill quagga and zebra mussel
juveniles and larvae in seconds and protects water bodies from the many destructive invasive
species that hitchhike on trailered watercraft. Finally, it enables you to comply with state and
federal laws prohibiting the spread of quagga and zebra mussels. Failure to comply could result
in your boat being impounded and you could be subject to criminal prosecution.
In General, when a water body is known to be infested with invasive species:
• Boats entering the water are not required to be inspected and cleaned.
• Boaters leaving the water should have their craft inspected, cleaned, and ushed according to
these Procedures (for ballast system) and state/Federal laws (for all boat and trailer requirements).
When a water body is known to NOT be infested with invasive species:
• Arriving boaters should be inspected according to state/Federal laws (for all boat and trailer
requirements) and these procedures (for ballast system) before entering the water. If ANY mussel
adults, juveniles or larvae are discovered, a complete cleaning of all required equipment is required.
• Boats leaving the water are not required to be inspected and cleaned.
Be sure to check state and federal laws and regulations to be sure you are complying with
requirements when entering or exiting bodies of water known to be infested with invasive species.
