 2023 OWNER’S MANUAL 
BALLAST SYSTEMS
Models
Ballast systems are found on all models. The NXT, X, XT, and X Star 
models utilize triple or quad hard tank ballast systems. If the boat 
includes the optional Surf Star System, two additional plug-in 
ballast bags are added to the aft sundeck compartments. 
On NXT models, additional integrated ballast bags may be installed 
optionally. These are installed beneath the port and starboard 
cockpit seats. They enhance the NXT’s wave potential. 
The ProStar uses a single MTS hard tank designed for competition 
training. For the most part, the MTS tank functions similarly to the 
multi-tank systems found on the NXT, X, XT, and X Star. However, 
the MTS tank is not compatible with Surf Star plug-in ballast. 
Purpose
Ballast systems are specially designed for each model to enhance 
the boating experience. By creating deeper, more dynamic waves, 
beginners and professionals alike can have experiences that are 
more enjoyable—even record-setting. For simple outings and 
improved, faster handling, ballast systems may be left empty. 
Location 
Ballast tanks are located under the deck, in the hull, hidden 
from sight. Optional plug-in bags are located in the aft sundeck 
storage areas, on either side of the engine compartment. The 
ballast outflow vents are located on the upper perimeter of the 
hull. Depending on the model, the overflow may be on the bow or 
the gunwale. Fill, empty, and overflow locations should never be 
obstructed.
On all X, XT, and Star models, ballast fill/empty locations are 
located underwater and should be kept clear of debris. (See the 
“Care and Maintenance” section of this Owner’s Manual for more 
details.) NXT Series models pump ballast water in from the hull 
bottom, but pump water out of thru-hull vents located on the hull’s  
sides. Ballast overflow vents are located on the side of the hull. 
Ballast switches are found on the screen and the manual helm 
switchpack. The location of the manual switchpack varies on 
some models. On the NXT, it is located on the dash mount. On X, 
XT, X Star, and Pro Star models, it is located to the left of the dash 
touchscreen. In addition to the manual switchpack, ballast fill 
levels can also be controlled via any X, XT, or Star video display 
(see the “X and XT Screen Operations” section of this  
Owner’s Manual).
