Jabsco Mastercraft Ballast Pump - 12V

The Jabsco Mastercraft Ballast Pump - 12V is a direct OEM replacement for Mastercraft wakeboard and surf boat ballast systems, engineered to move water quickly and reliably for ballast tank operations. Part number 18670-9407 comes factory-equipped with a green Run Dry impeller and pre-installed electrical quick connector, eliminating setup guesswork and allowing immediate installation once hoses are connected and power leads are engaged.

At 6.8 pounds and measuring 6 x 5 x 10 inches, this 12-volt pump is sized for standard Mastercraft installations and delivers consistent flow through marine-duty construction. The Run Dry impeller design protects pump internals when operating without water load, preventing cavitation damage during dry-run scenarios common when ballast tanks are being filled or emptied. Electrical connectors match OEM specifications exactly, ensuring compatibility with existing wiring harnesses and control systems on Mastercraft equipped vessels.

This replacement pump addresses boaters who have experienced ballast pump failure or deterioration in salt-water environments where corrosion and mineral buildup compromise pump seals and impeller efficiency. Weekend recreational tow sport athletes and serious competitive wakeboarding teams both rely on ballast system integrity for achieving the precise water displacement needed to shape waves and wakes. Rather than troubleshooting original equipment, the direct Mastercraft OEM replacement approach eliminates compatibility risk and restores system performance without modification.

Jabsco is recognized across the marine industry for pump durability in demanding freshwater and saltwater applications. This ballast pump carries the reliability standard expected in OEM-level replacement parts, backed by proven performance across Mastercraft's fleet of wake and surf boats operating in varied climates and usage patterns.
