Gravity Ballast System
The Gravity Ballast System is an electronically controlled ballast
system that can be operated from the driver's seat. The switch
panel to the 3 position system is located directly below the
shifter mechanism. Each switch allows independent filling and
draining of each ballast container by simply hitting the fill or
drain switch. If the system fails to fill or drain, you may check the
resettable breaker on the switch panel, or the separate ballast
fuse block located under the dash area. The ballast bags can be
found in the front ski locker and in the rear v-drive storage areas
depending on the the model and ballast system.
When bags begin to vent, shut off!
Do Not overfill ballast bags!

Care should be taken that the ballast bags are situated properly
with the hose on the bottom and that all fittings are installed
securely. The bags should not be twisted and the bags should
be free to expand and drain completely. Care should be taken
to prevent sharp objects from coming in contact with the bags.
Cuts and punctures to the bags are not warrantable.
Each Gravity Ballast System also includes manual shut off valves
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 the system.
Priming the System
To allow water into the system, the Gravity Ballast System utilizes
a impeller pump to force water into the system. This allows the
ballast system to be filled while sitting still or running slowly. If
air becomes trapped in the system, it may be necessary to idle
the boat and allow the fill pump to prime fully.
Auto Timers
The pumps have a pre-set run time. The pumps will shut off
automatically to prevent overfilling. If the switch is turned off
and back on, the pumps will run an additional minute. (See
dealer for additional information or reprogramming.)
