Johnson Pump Rapid Rogue Ballast Pump – 30 GPM – 12V – 10-24939-18

The Johnson Pump Rapid Rogue Ballast Pump (10-24939-18) is a high-capacity, reversible ballast pump engineered for rapid filling and draining of ballast tanks on wakeboard and wakesurf boats. With a powerful 30 gallons-per-minute flow rate, the Rapid Rogue dramatically reduces fill and drain times, allowing riders to get on the water faster and fine-tune ballast levels with ease.

This pump features a reversible flexible impeller design, enabling a single pump to handle both fill and drain functions—eliminating the need for separate pumps or valves. Its self-priming capability and dry-run tolerance make it reliable in demanding marine environments, while built-in thermal overload protection helps safeguard the motor during extended operation.

Designed for tight installations, the Rapid Rogue offers a compact footprint with rugged, corrosion-resistant construction suitable for both freshwater and saltwater use. Whether upgrading an existing system or building a custom ballast setup, this pump delivers fast, dependable performance trusted by OEMs and serious watersports enthusiasts.
