The Jabsco Wakeboard Ballast Puppy is a high-performance reversible ballast pump system designed specifically for wakeboard and wakesurf boats. Engineered for fast fill and drain times, this 12V ballast pump delivers reliable, self-priming performance while giving boat owners precise control over ballast tanks using the included reversing switch.
Trusted by boat manufacturers and aftermarket installers alike, the Ballast Puppy is a proven solution for creating the perfect wake with minimal effort.
The Ballast Puppy’s reversible impeller design allows the pump to both fill and drain ballast tanks using the same pump and plumbing. This eliminates the need for additional valves or pumps, simplifying installation while reducing system complexity.
This model includes a reversing switch, enabling easy direction control for filling or emptying ballast tanks at the touch of a button. The switch provides smooth, reliable operation and allows for intuitive ballast management from the helm or control panel.
Built with a flexible impeller, the Ballast Puppy is fully self-priming, capable of lifting water vertically and operating efficiently even when mounted above the waterline. The robust motor and pump housing are designed for continuous marine use.
Manufactured by Jabsco, a leader in marine pumping solutions, this ballast pump features corrosion-resistant materials and sealed motor construction to withstand harsh freshwater and saltwater environments.
The Ballast Puppy is engineered for speed, moving approximately 80 lbs of water per minute (9 GPM). It can fill a standard 40-gallon ballast tank in under five minutes.5 Because the motor is reversible, a single pump handles both the "Fill" and "Drain" functions via a simple polarity-reversing switch.
The most common cause of ballast pump failure is "dry running"—leaving the pump on after the tank is empty. The 18220-1127 features a proprietary sensor that detects the absence of water. After a short period of dry operation, it cuts power to the motor, protecting the green polyurethane impeller from heat damage.
Bronze Pump Head: Unlike plastic alternatives, the bronze head resists cracking and handles the high pressures required for ballast bags and tanks.
Ignition Protected: Meets USCG 183.410 and ISO 8846 standards, making it safe for installation in gasoline engine compartments.
Self-Priming: The pump can pull water from up to 3 feet below its mounting position, ensuring it starts moving water immediately without needing to manually prime the lines.

"To maximize the life of your impeller, mount the pump as low as possible in the boat to reduce the 'suction lift' required. While it is self-priming to 3 feet, keeping it closer to the waterline ensures faster fills. Also, always use 1" ID reinforced hose on the suction side; standard thin-walled hose can collapse under the vacuum created by the pump, causing it to shut down prematurely."
