Gravity Ballast System
(continued)
Each Gravity Ballast system also includes a manual shut
off valve in case of emergencies. If closed, the valve will
prevent any water from entering the system and is only
used in emergency situations. Under normal use the valve
should remain open to allow full flow of water into system.
Priming the System
To allow water into the system, the Gravity Ballast system
utilizes a scooped intake stainer to force water into the
system. This allows the ballast system to be filled while
running or sitting still. If air becomes trapped in the system,
it may be necessary to run the boat at planing speeds to
force water into the system and allows the fill pump to prime
fully. Once the pump has primed it is no longer necessary to
run the boat for filling. This situation may occur if the boat is
trailered.
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!
When bags begin to vent, shut off!
DO NOT OVERFILL BALLAST BAGS!
