SHURFLO Piranha Pump Rebuild Kit 94-620-00 for 800/1100 GPH 12V — OEM cartridge, reduces noise

SHURFLO 94-620-00 is a genuine replacement cartridge and rebuild kit engineered to restore Piranha 800/1100 12V livewell, aerator, and ballast pumps to reliable operation.

If your Piranha-series pump has lost pressure, is noisy, or is circulating unevenly, replacing the internal cartridge with an OEM SHURFLO kit is the quickest way to regain dependable flow without buying a whole new pump. This beige replacement cartridge and rebuild kit fits the 800 and 1100 GPH 12V models and is built for routine marine maintenance, saving time and cost for anglers, boat owners, and service technicians.

How will this rebuild kit fix pump performance on my boat?

Installing the SHURFLO 94-620-00 cartridge addresses worn internal components that cause reduced flow, cavitation, or excess vibration. The kit replaces the critical moving and sealing parts so the existing housing and motor can deliver close-to-original output again.

• Replaces internal cartridge components that wear with use
• Reduces noise and vibration by restoring tolerances
• Improves flow consistency for livewells, bait tanks, and ballast systems

Is this kit compatible with my Piranha 800 or 1100 pump?

The 94-620-00 kit is manufactured as an OEM replacement for SHURFLO Piranha-series pumps rated at 800 and 1100 GPH in 12V configurations. It was designed to drop into the original pump housings without modification when performing standard rebuild procedures.

• Fits Piranha 800 and Piranha 1100 12V models
• Direct-fit cartridge—no custom machining required
• Works for livewell, aerator, and ballast pump assemblies

What benefits should I expect after installing this replacement cartridge?

After installation you should notice steadier water circulation, fewer air pockets, and quieter operation compared with a worn cartridge. Restoring the internal components helps extend the life of the pump housing and motor, making it a cost-effective alternative to full assembly replacement.

• Restores smoother, more consistent water flow
• Reduces the likelihood of premature motor strain
• Helps maintain livewell oxygenation and ballast transfer performance

How difficult is the rebuild—can I do it myself?

The rebuild is intended for routine maintenance and can be completed by a handy boater or technician with basic tools and mechanical experience. Follow the pump service instructions: remove the housing, extract the old cartridge, inspect seals, install the new cartridge, and test the pump for leaks and proper flow.

• No specialty tools required—just common hand tools
• Follow torque and seal guidelines in the service manual
• Allow a brief sea trial to confirm restored operation

Who this kit is for: the SHURFLO 94-620-00 repair and rebuild kit is ideal for anglers, charter operators, marine technicians, and boat owners who want an OEM, cost-effective way to restore Piranha 800/1100 pump function. Choose this kit if you prefer to maintain the original pump assembly, minimize downtime, and keep livewells, bait tanks, and ballast systems performing reliably on freshwater and saltwater vessels.
