Ballast pump cartridge. Can be used to replace the cartridge of a ballast pump without replacing the entire pump, which is cheaper and easier than buying a new pump. Works with the 750, 800, and 1100 GPH pumps.
Our cartridges are OEM Malibu cartridges with a plug and play connector to simplify installation. This feature will not be found on the majority of cartridges sold online. For older boats without the connector you can simply remove it and use wire connectors for installation.
The best way to identify if you need the cartridge or the whole pump is to determine if it's leaking or not. If the pump is leaking, it's likely the housing has cracked and you will need a whole new pump; otherwise, you'll likely just need the cartridge.
