Gravity Ballast System
The optional Gravity Ballast System is an electronically con-
trolled ballast system that can be operated from the driver's
seat. The Gravity system is available in a 1 or 3 position
system. The switch panel to the 3 position system is located
directly below the shifter mechanism, and the 1 position sys-
tem is operated from a switch on the dash. 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 or tanks can be found in the front
ski locker, under the rear seat, or 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 prop-
erly with the fill hose on top and drain hose on 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 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 the system.
Priming the System
To allow water into the system, the Gravity Ballast System
utilizes a scooped intake strainer 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.
