What's in the Box
The company identifies this product as a carburetor repair seal kit. Exact component shapes and quantities can vary by carburetor application, so compare the supplied parts with the original components before installation. A complete carburetor, engine, fuel line, and carburetor float are not identified as included components in the company product record.
Installation Notes
- Turn the engine off and disconnect the fuel supply before beginning work. Allow the engine to cool completely.
- Remove the carburetor according to the engine service manual, noting the positions of linkages, hoses, and adjustment components.
- Disassemble the carburetor on a clean, well-lit work surface and retain the original parts for comparison.
- Remove the old gaskets, seals, and packing components. Clean the reusable metal parts with a suitable carburetor cleaner and make sure the passages are clear.
- Do not use solvent on components that may be damaged by the cleaner. Replace only the components appropriate to your carburetor configuration.
- Install the replacement sealing components carefully, ensuring that each gasket and seal is correctly positioned and seated.
- Reassemble and reinstall the carburetor, reconnecting all hoses and linkages in their original positions.
- After installation, follow the engine service manual for leak checks, idle adjustment, mixture adjustment, and final running checks.
Troubleshooting & FAQ
Which engines does this repair seal kit fit?
It is listed for selected Johnson/Evinrude 2-stroke outboards rated from 4 HP to 15 HP. The documented applications include 4, 4.5, 5, 6, 7.5, 8, 9.9, 14, and 15 HP models with the specific year ranges shown in the compatibility table. Always verify the exact engine and carburetor application before ordering.
Is this a complete carburetor?
No. This is an aftermarket carburetor repair seal kit intended for service of a compatible original carburetor. The carburetor body and complete engine assembly are not included.
Is the carburetor float included?
The company product record identifies the item as a repair seal kit and does not list a float as an included component. Do not assume that a float is included; compare your existing float with the service requirements for your carburetor.
Can I use it if my engine is in the same horsepower range?
Not necessarily. Horsepower alone does not confirm fitment. The engine brand, horsepower, 2-stroke configuration, model year, and carburetor reference must all match the documented application.
What symptoms may indicate worn carburetor seals?
Possible symptoms include fuel leakage, hard starting, unstable idle, stalling, poor acceleration, or inconsistent fuel metering. These symptoms can also have other causes, so inspect the carburetor and follow the engine service manual before replacing parts.
Is this an OEM part?
No. This is an aftermarket replacement product. The numbers shown on this page are reference numbers used to help identify the intended application.

- Verify the engine model, year, stroke, horsepower, and carburetor reference before ordering.
- Compare the replacement parts with the original parts before installation. Do not force a component into place.
