Ballast Empty/
Fill Switches
(On Ballast-equipped Models Only)
On boat models equipped with a bal-
last system, a separate three-position
switch will allow for the lling or empty-
ing of the ballast tanks and/or bags. Be
aware that the engine must operate at
-
cesses. Check engine specications for
related engine idle speed, which may be
too low for the empty/ll operation to be
properly accomplished. Failure to increase
engine RPM to the required level may re-
sult in malfunction or permanent damage
to the ballast pumps that force the water
through the system. Such damage is not
covered under your warranty. The ballast
controls vary in location by model, and the
operator should determine exact location
prior to use. The three-position switches are clearly marked; FILL, OFF
(in center), and EMPTY.
An LED light is in the tip of each switch. At the conclusion of the FILL
process, the light will blink six times in succession, pause for two-to-
three seconds, and then blink an additional six times. This signals that
the FILL process is complete. If the system senses any potential prob-
lems, the LED lights may blink from one to ve times (each signies in-
dividual issues). If this occurs, see an authorized MasterCraft dealer for
analysis and correction. Do not attempt to correct the issue on your own
or continue to FILL the ballast as it may result in damage to the system.
Mirrors
Whether utilizing the standard mirror or the optional Extreme mir-
ror, just as you would in a car, you should always check that the mirror
is properly located to view behind the boat while it is underway. Also
be sure that it is securely attached to the windshield extrusion. Under
normal operation, there is a certain amount of vibration and over time
this can cause brackets and hardware to work loose.
Prior to operation of the boat, verify that the mirror
hardware is secure. Failure to do so may result in the
mirror detaching from the windshield extrusion. The
mirror could hit the operator or a passenger, resulting
in injury.
Plug ’n Play
The Plug ’n Play ballast system gives consumers the ability to mix
and match ballast loads as an option on V-Series boats. If ordered as
an option, the plumbing for the Plug ’n Play will come from the factory
ready to install bags forward and aft. MasterCraft strongly recommends
using only the Plug ’n Play bags from Fly High as they have been custom-
ized to t neatly in storage areas. The rear bags take into consideration
such factors as bulkhead dimensions and the raw water strainer location
of each specic model. The forward bags are built to the dimensions of
the storage area under the seats and around obstructions such as stereo
ampliers and wiring. Note that the bags are intended to be left inside
the storage compartments even when not lled with water. The bags,
particularly if they are wet, should not be left in contact with upholstery
anywhere in the boat.
The most important consideration in developing these additional bal-
last bags was to work within the maximum capacity of each Master-
Craft model in which they are equipped. WHEN THE PLUG ’N PLAY
BALLAST BAGS ARE FILLED, THE ADDITIONAL WEIGHT OF THE
BAGS AND WATER MUST BE SUBTRACTED FROM THE MAXI
MUM WEIGHT CAPACITY OF THE BOAT , WITH THE REMAINDER
LEFT FOR PASSENGERS AND GEAR! It is always the operator’s
responsibility to ensure the weight of their specic MasterCraft boat,
persons aboard, ballast and gasoline weight, and all gear are within
Coast Guard limits.
An objective in engineering this system was for the secondary ballast bags
to ll and empty with the existing ballast pumps at the ip of a switch. In or-
der to accomplish this, the auto-ll-and-empty system that is equipped on all
boats without the Plug ’n Play option is bypassed. Although you can use the
BIG’s Ballast screen to see if the tanks are full (or listen for the overow), there
are no sending units in ballast bags, so no bag level readout is available on the
BIG. The operator should open the front and rear storage areas where the
bags are located to watch the actual bags themselves to see when they
All boats have weight limits. Failure to adhere to the posted limits
can cause operation instability and/or the boat to sink. This may
result in serious injury or death, as well as significant damage to
the boat, which will not be covered by warranty. WHEN THE
PLUG ’N PLAY BALLAST BAGS ARE FILLED, THE ADDI-
TIONAL WEIGHT OF THE BAGS AND WATER MUST BE
SUBTRACTED FROM THE MAXIMUM WEIGHT CAPAC-
ITY OF THE BOAT , WITH THE REMAINDER LEFT FOR
PASSENGERS AND GEAR!
