pumped into the rest of the ballast system to evacuate through the
quick connect, which can result in flooded storage compartments
which could sink the boat.
The original bridge connector in the ballast system must be rein-
stalled if the optional plug-in bags are removed from the system.
Failure to do so will result in any water in the ballast system
evacuating into the storage compartment, potentially flooding
the storage compartments. This could sink the boat, resulting in
serious injury or death.
In systems that operate on timers (XStar, ProStar, X Series and
XT Series models), note that the timer operation varies by model.
Timers may also be impacted by the addition of optional bags. See
your authorized MasterCraft dealer for assistance in determining
proper timer settings.
Special Attention
Be aware that the engine must be operated at 1500 RPM during the
fill and empty processes. Check engine specifications for related
engine idle speed, which, in some instances, may be too low for
the empty/fill operation to be properly accomplished. Failure to
increase engine RPM to the required level may result in malfunction
or permanent damage to the ballast pumps that force the water
through the system. Such damage is not covered under your
warranty.
Special Attention
NEVER tow a trailer with water in the boat’s ballast tank(s)! Even
small amounts of water can cause serious problems with the
required balance of the boat on the trailer (see the Trailers section
of this Owner’s Manual if you own a MasterCraft trailer).
Note that this information is also applicable when towing with
trailers built and sold by other manufacturers. Correct balance is
critical to safe trailering.
Never tow a boat with water in the ballast tank(s). doing so may
damage the boat and trailer, resulting in loss of control that could
cause serious injury or death.
Additional Special Attention
Ballast pump impellers MUST be replaced on a regular basis (at
least annually, but more often as necessary). Its purpose is to move
water from the intake on the hull bottom and into the ballast tank,
and vice versa when emptying the ballast tank. Through usage, the
impeller, by design, will wear and eventually need replacement (see
Care and Maintenance section of this Owner’s Manual). Authorized
MasterCraft dealers can help to locate any and all pumps and
impellers. Failure to follow directions may result in damage to the
ballast pump that is not covered under warranty.
PYLONS
Models
All
Purpose
When properly utilized, ski pylons allow skiers the opportunity to be
towed behind the boat with a sensible and unobstructed view by
individuals in observer seats.
Location
Varies by model, but pylons are generally adjacent to or integrated
within aft seating. (See Guide to Individual Models in this Owner’s
Manual for specific model locations.)
Operation
See the Ski/Wakeboard Rope information under Additional Safety
Support in this section of the Owner’s Manual. Avoid tangling rope
around the pylons or any other portion of the boat.
Failure to follow instructions regarding the care and maintenance
of ballast pumps as outlined in this Owner’s Manual can result in
damage to the ballast pump that is not covered under warranty.
Troubleshooting
If the ballast pumps do not turn ON when the switch is activated
or the touch screen is used, check that the circuit has not tripped
on the main circuit breaker panel, or use PDM diagnostics to reset
the fault. Continual tripping after reset is indicative of an issue that
requires the attention of an authorized MasterCraft dealer.
If the ballast pumps do not work and the circuit breaker has not
been tripped, it is likely that the pump has malfunctioned. This can
be the result of running the impellers while the tanks are empty. Re-
gardless of cause, it is necessary to take the boat to an authorized
MasterCraft dealer to determine whether the impeller and/or pump
must be replaced.
Your authorized MasterCraft dealer has an extensive troubleshoot-
ing tree for ballast systems that includes parts of the system that
are not accessible to the consumer. Because a malfunctioning
ballast system can cause problems with the control of the boat, no
potential issue that arises with the system should ever be ignored.
