2023 OWNER’S MANUAL
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
In standard ballast systems, the engine must be operated at
1500 RPM or more during the fill and empty processes for optimal
performance. On models equipped with the FastFill Ballast
System (see the FASTFILL BALLAST PUMP section of this Owner’s
Manual) the engine must be operated under 1500 RPM for optimal
performance. Operating the FastFill system at higher RPM can
cause the low voltage alarm to sound. 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 or decrease engine RPM to the required level
may result in malfunction or permanent damage to the
ballast pumps that force water through the system or to the
engine’s electrical 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.
