Shurflo 357-116-10 Piranha Ballast Pump, 12V Submersible, 800 GPH

The Shurflo Piranha Ballast Pump (357-116-10) is a 12V submersible pump built to move water fast and reliably in boat ballast systems. Rated at 800 GPH, it is designed for wake boats, ski boats, fishing boats, and other marine water transfer applications where consistent fill and drain performance matters. The pump uses a heavy duty, water cooled motor for dependable operation and a high density nylon housing that resists impacts, corrosion, and long term exposure to both freshwater and saltwater environments.

A patented anti airlock system automatically clears trapped air from the pump to maintain steady water flow during ballast fill and drain cycles, preventing the interruptions that can occur with lesser pumps. The removable cartridge design gives quick access for cleaning and replacement, cutting down on maintenance time and keeping the ballast system running efficiently through the boating season. Fully submersible, the pump is equipped with a corrosion resistant tinned 6 ft wire assembly for dependable electrical connections underwater. It is ISO 8846 ignition protected, meaning it is certified safe for installation in engine compartments alongside fuel systems and other ignition sources. This combination of durable construction, anti-airlock technology, and serviceable cartridge design makes the 357-116-10 a practical choice for boaters who need consistent ballast water transfer without frequent pump replacement.
