Jet Performance Quadrajet Marine Carburetor - Remanufactured

The Jet Performance Quadrajet Marine Carburetor line delivers professional-grade fuel delivery built on the proven Rochester Quadrajet 4-barrel spread-bore platform. Each unit is fully remanufactured to exacting standards, purpose-built for the demanding conditions of marine engine applications, and engineered to restore peak fuel delivery performance with confidence.

Remanufactured to the Strictest Quality Standards:

• Completely disassembled, inspected, and rebuilt using the highest-quality components
• Critical internal fuel passages thoroughly cleared to ensure optimal fuel flow
• All wear surfaces evaluated and replaced as needed for extended service life
• Throttle shafts and bores inspected to eliminate vacuum leaks and ensure precise fit
• Factory-tested to verify performance meets or exceeds OEM specifications before shipping

Marine-Specific Design and Construction:

• Cast surfaces are iridited and shafts and pump arm are PTFE-coated for superior corrosion resistance in both fresh and saltwater environments
• Purpose-built for marine use with no automotive vacuum ports — not interchangeable with automotive applications
• Meets United States Coast Guard (USCG) safety standards for marine fuel systems
• Compatible with spread-bore marine intake manifolds including Edelbrock Performer and similar designs
• Available in electric choke and remote choke configurations to suit a range of applications

Rochester Quadrajet Platform Advantages:
