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 in -
cludes 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!
For your convenience, a DC outlet has been included on
the panel to the right of the driver’s seat. Some models
have receptacles located in the glovebox. Location varies
by model.
