The Johnson Pump Aqua Series Replacement Cartridge Motor is a simple, efficient way to restore water flow in compatible marine pump systems without replacing the entire pump assembly. Designed for use with Johnson Pump Aqua Void bilge pumps and Aqua O2 aerator pumps, this replacement cartridge helps boaters get back on the water quickly with less downtime and less maintenance. Available in 500 GPH and 800 GPH options, it can be used either as a direct replacement or as an easy output upgrade on compatible setups.

Key Features

• Tool-Free Service: The cartridge uses a twist-and-pull design for fast removal and replacement with no tools required.
• Two Flow Rates: Offered in 500 GPH and 800 GPH versions to match your pump configuration or increase performance on compatible systems.
• Marine Pump Compatibility: Built for Johnson Pump Aqua Void bilge and Aqua O2 aerator applications where dependable water movement is essential.

Because only the motor cartridge is replaced, service is cleaner and faster than swapping out a complete pump. That makes this Johnson Pump cartridge a smart choice for preventive maintenance, emergency onboard spares, or quick repairs during the season. Anglers, recreational boaters, and marine technicians alike appreciate the convenience of keeping a compatible replacement cartridge ready when pump performance drops.

Johnson Pump is a trusted name in marine plumbing and pump systems, and the Aqua Series cartridge motor reflects that focus on practical, dependable serviceability. Choose the correct flow rate for your application to keep bilge or aerator performance operating as intended.
