Gravity Ballast System
The optional Gravity Ballast System is an electronically
controlled ballast system that can be operated from the
driver’s seat. The Gravity system is available in a 1, 2 or 3
position system. The switch panel to the 2 and 3 position
systems is located directlybelow the shifter mechanism, and
the 1 position system 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.
Care should be taken that the ballast bags are situated
properly 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 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.
