Livewell equipment often uses several different systems together. A water pickup scoop helps feed an existing transom intake, an air bubbler adds oxygen through air stones, and a motor cartridge replaces the powered component inside its matched pump housing. Choose the actual function you need before selecting a part.
Water supply, oxygenation and circulation are different jobs
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.
Simplified functional symbols, not scaled product or installation drawings.
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.

Intake lengths describe the listed housing, not universal tube compatibility. Cartridge classes must be matched to the original pump model.
Five checks before ordering livewell parts
- Identify whether the failed component is an intake scoop, air system or electric water-pump motor.
- Measure the transom intake and fit clearance before choosing the short 3-3/8-inch or long 4-3/4-inch EZ Pump pickup.
- For PAS1DP, verify the 12V DC air supply and whether the original livewell uses two air-stone outlets.
- Match Attwood Tsunami cartridge 5620-6 to its T500 pump class or 5622-6 to its T800 pump class.
- Follow manufacturer installation instructions for any plumbing or electrical work and confirm the water source and discharge arrangement.
