The Gravity 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.
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!
