2023 OWNER’S MANUAL

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. Regardless 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 
troubleshooting 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. 
FOUR ZONE BALLAST
Models
XStar and X Series Models (excluding X26)
Purpose
The four zone ballast system features four individual ballast zones 
to add customization to the wakes and waves produced by your 
boat. Each zone can be filled to custom fill levels using the helm 
mounted touchscreen. Profiles in the screen for wakeboarding and 
surfing also control factory configured ballast tank fill levels. 
Location
Each of the four tanks corresponds to a particular ballast zone. 
The rear port and starboard tanks flank the engine, aft of the 
boat’s center of gravity. When optioned with the Surf Star System, 
ballast bags are plumbed into these tanks to add extra weight to 
the boat. The third ballast tank is located under the walkway to the 
bow of the boat. 
The fourth ballast zone features a “U” shaped tank that runs the 
width of the boat just forward of the engine. This tank is referred to 
as the “midship tank.” The midship tank should be filled according 
to the pre-set wakeboard and surf profiles in the boat.
