Edelbrock 1409 Marine Performer Carburetor — 600 CFM, 4-Barrel
The iFJF 1409 Marine Performer Carburetor brings the proven AFB-style design to marine applications. With 600 CFM airflow, electric choke, and USCG-compliant safety features, this carburetor is a direct performance upgrade for Chrysler Marine and Chevy Marine V8 inboard engines. The air valve secondary system delivers smooth, predictable power delivery that's essential for docking, trolling, and hole-shot acceleration.
Marine-Specific Design
-
Sealed Throttle Shaft Bearings — Eliminates fuel vapor leakage into enclosed engine compartments
-
Overflow-Safe Vent Design — Bowl vents route excess fuel back through the venturi instead of spilling externally
-
Marine Fuel Curve — Calibrated for sustained high-load marine operation at 3,000-4,500 RPM cruising speeds
-
Corrosion-Resistant — All external hardware is stainless steel or dichromate-coated for saltwater durability
-
Two-Piece Body — Easy tuning access without full disassembly
Applications

Frequently Asked Questions
Q: Is this a genuine Edelbrock carburetor?
A: This is an aftermarket replacement for the Edelbrock 1409, engineered to the same specifications and dimensions for direct bolt-on installation.
Q: Does it include mounting gaskets?
A: Yes, a base gasket and mounting hardware are included. For marine applications, always use a marine-grade intake manifold gasket rated for enclosed engine compartments.
Q: Can this be used on a freshwater-cooled boat?
A: Yes, it is suitable for both freshwater and saltwater applications. For saltwater use, we recommend regular inspection of external surfaces and periodic application of corrosion inhibitor spray.
Q: What's the break-in procedure?
A: No special break-in is required. Install, connect the 12V choke wire, set idle speed to 650-700 RPM (in gear, in water), and verify float level after the first hour of operation.
Q: Can I convert my 2-barrel marine engine to this 4-barrel?
A: Yes, if you change to a 4-barrel marine intake manifold. The 1409 is an excellent upgrade that improves both performance and fuel economy at cruising speeds when paired with the correct intake.
