A livewell intake, an air pump and a motor cartridge can all be described as aeration equipment, but they do different jobs. Use the original component's shape and manufacturer number to distinguish a passive water pickup, a 12V air bubbler and a replacement water-pump motor.
What does the original livewell part do?
Water pickup scoop
Uses existing water flow and intake plumbing; no electrical motor inside the scoop.
Air bubbler
A 12V air pump sends bubbles through submerged air stones; it does not circulate water.
Pump motor cartridge
A removable powered motor fits the specified Tsunami T500 or T800 pump housing.

Do not confuse the components. The EZ Pump scoop helps supply water while underway. Pro-Air supplies air through stones. Attwood cartridges belong in matching powered pump assemblies. These parts cannot replace one another.
Identify the correct replacement component
- Photograph the old transom fitting and the separate equipment inside the boat.
- Check whether the failed part has electrical wires or is simply a passive intake scoop.
- Compare the intake housing's colour, length and tube layout before changing a fitting.
- For Attwood replacement motor cartridges, read the old Tsunami T500 or T800 model marking.
- Check air-stone tubing, water inlet plumbing and pump connections individually rather than replacing unrelated components.

Intake lengths describe the listed housing, not universal tube compatibility. Cartridge classes must be matched to the original pump model.

T-H Marine EZ-WHT-2-DP — White short intakeThe smaller white intake is 3-3/8 inches long and should be checked against the old transom fitting.Check listing and availability
Identify the air-pump and air-stone system
T-H Marine PAS1DP — Pro-Air dual-outlet systemLook for a separate 12V air pump with air tubing and submerged air stones. This is not a water pickup.Check listing and availability
