Outback Optional Gravity Ballast System
NOTE: When filling the rear ballast bag in the Outback, the
rear seat should be raised to the upper position to allow
the bag to expand freely.
Each Gravity Ballast System also includes an in-line water
strainer before the manifold. This strainer will keep debris out
of the solenoid valve and should prevent the valve from getting
clogged up and forced open. The strainer cover should be
removed periodically and the filter screen cleaned to prevent
debris buildup on the mesh screen. Be careful when removing
the cover not to lose the O-ring used to seal the cover. Also, the
strainer should be removed and drained during winterization.
To fill the ballast system, press the fill switch. To empty, press
the empty switch. With the ballast full, the boat may porpoise
at speeds above 25 mph.
Empty ballast before trailering the boat. DO NOT trailer
boat with ballast full!
The Gravity 1 Ballast System utilizes a manifold and a solenoid
valve to independently fill each bag or tank. The solenoid
valves have a small toggle switch that can manually override
the opening of the valve. The manual toggle switch needs to
be in the “down” position to allow the system to be controlled
by the switches in the dash area. If the manual toggle switch is
turned to the “up” position, the valve will be open all the time
and cannot be controlled by switches in the dash area. If the
ballast system fills continuously while running the boat, check
to make sure the manual override toggle switch is in the “down”
position. If it continues to fill and the manual toggle switch is
in the “down” position, check for debris that may have clogged
the solenoid valve forcing the valve to stay open. If the valves
continue to fill, closing the manual emergency shut-off valve
will prevent any water from entering the system.
