SHURflo Piranha 357 Livewell Pump & Cartridge Parts
The SHURflo Piranha 357-113-10 is an 800 GPH, 12-volt centrifugal pump designed to circulate water in a marine baitwell or livewell. It uses a replaceable impeller-and-motor cartridge, 94-620-00, so a damaged cartridge can be changed without purchasing a complete pump when the main housing remains serviceable.

The 94-620-00 cartridge is also identified by the manufacturer for Piranha 357-103-series 1100 GPH livewell pumps and applicable 800/1100 GPH ballast pumps. The 600 GPH Piranha 357-013-series uses 94-619-00 instead. These cartridge families are not interchangeable merely because their housings look similar.

Correct installation and service
- Before removing the cartridge, turn off electrical power and close the seacock. The manufacturer requires the seacock to be closed before the cartridge is removed.
- Remove the locking screw and spacer, loosen the blue retaining collar counterclockwise, and withdraw the cartridge.
- Clean debris from the housing. Reinsert the cartridge, hand-tighten the collar and reinstall the screw and spacer snugly without overtightening.
- For below-waterline installations use suitable marine hose and clamps, route the outlet upward without sags, and use an accessible seacock.
- Do not run dry. Restore the supply and test the pump for leaks and correct water circulation after service.
