Why Choose the iFJF 18-7046 Kit?
Vintage Johnson and Evinrude outboards are legendary for their reliability — but their carburetors suffer from the same ethanol-related degradation as any other marine engine. OEM carburetor assemblies for these engines are often discontinued or priced at $300+. The iFJF 18-7046 kit provides an affordable, high-quality alternative that restores factory performance without the factory price tag.
Frequently Asked Questions
Q: What Johnson/Evinrude models does this fit?
A: This kit covers multiple OMC/Johnson/Evinrude carburetor applications. Verify fitment by your carburetor's OEM part number (439076, 398526, 390055, 435443, 392550, 434888, or 383906). Contact us with your engine model and serial number for confirmation.
Q: Is this the same quality as GLM 40570?
A: The iFJF 18-7046 kit is manufactured to the same specifications as the GLM 40570 kit — using ethanol-resistant materials and precision-machined components. It is a direct functional equivalent.
Q: Does the kit include float and jets?
A: No. The float and jets are typically reusable. The kit includes all soft components that wear out: gaskets, seals, o-rings, needle & seat, and welch plugs.
Q: Will this fix fuel leaking from my carburetor?
A: If the leak is from the float bowl gasket (common) or inlet needle not sealing properly (also common), then yes — this kit includes both components. If the carburetor body is cracked, the leak requires carburetor replacement.
Q: How many kits do I need for a V4 outboard?
A: V4 Johnson/Evinrude outboards typically have 2 carburetors. You'll need 2 kits for a complete rebuild. Ordering 2 kits is recommended so both carburetors perform identically.
