iFJF Carburetor Rebuild Kit for Mercury/Mariner Outboards — Pack of 3, Gaskets & Jets

iFJF 18-7750-1 is a complete three-pack carburetor rebuild kit that replaces Mer-cury/Mariner part 1395-8236354 and contains gaskets, O-rings, jets, fuel pipe, filter and band clamps to restore carburetor function on a wide range of outboard models.

If your Mer-cury or Mariner outboard is running rough, leaking, or suffering poor throttle response due to worn carburetor parts, this iFJF rebuild kit supplies the common replacement pieces technicians need. The kit is offered as a pack of three identical rebuild sets and is made to fit many older Mer-cury/Mariner WME-series carburetors as well as compatible Mallory and Penta part numbers. It’s intended for DIY maintenance or professional service to refresh components without buying an entire carburetor.

Which engines and part numbers does this kit replace?

This kit is designed to interchange with several Mer-cury/Mariner part numbers and legacy replacements used in many outboard models. It lists multiple factory numbers so you can confirm fit before purchasing.

• Direct replacement for Mer-cury Marine 1395-8236354 and related numbers (1395-8236353, 1395-8236352, 1395-8236351, 1395-823635, 1395-811222, 1395-9599).
• Also cross-references GLM 40650, Mallory 9-29707, and Penta 35254.
• Compatible with many WME-series Mer-cury/Mariner carburetors across numerous model numbers.

What parts are included and what do they fix?

The iFJF rebuild set bundles the common consumables that fail first in aging carburetors. Replacing these items helps restore fuel metering and seal integrity without intensive machine work.

• Gaskets and O-rings — restore proper sealing between carburetor bodies and floats to eliminate leaks.
• Jets and needles — replace worn metering elements to improve idle stability and throttle response.
• Fuel pipe and inline fuel filter — refresh fuel delivery path and trap debris before it reaches jets.
• Three band clamps per pack — secure hose connections and prevent fuel seepage.

How do I use the kit; is it DIY-friendly?

The kit is intended for technicians and mechanically-inclined boat owners. Basic hand tools, a clean workspace, and an exploded diagram of your carburetor are all that’s needed for most rebuilds.

• Disassemble the carburetor on a clean bench and note or photograph part locations before removal.
• Swap old gaskets, O-rings, jets and fuel fittings for the new kit components, replacing any corroded screws or badly damaged parts as needed.
• Reassemble using correct torque and test for leaks and smooth throttle operation before returning to service.

Will this kit restore performance and prevent future issues?

Replacing worn consumables can significantly improve carburetor operation but it’s not a guaranteed cure for all problems. This kit addresses the most common wear items; more complex issues may require ultrasonic cleaning or replacement parts beyond the kit.

• Helps reduce fuel leaks, hesitation, and inconsistent idling caused by degraded seals and jets.
• Not a substitute for rebuilding damaged castings, warped float bowls, or severe internal corrosion.
• Recommended as preventive maintenance for stored or high-hour engines to help maintain reliability.

Who this kit is for: boat owners, hobbyist mechanics, and marine repair shops working on older Mer-cury/Mariner outboards who need an affordable way to refurbish carburetors without buying complete replacements. Choose the iFJF 18-7750-1 pack of three if you service multiple motors or want spare rebuild sets on hand for routine maintenance and seasonal tune-ups.
