Troubleshooting & FAQ
How do I know if this is the correct kit for my engine?
Verify your engine's model, horsepower, and year against the "Engine & Model Compatibility" table. You can also match the OEM part number from your service manual to the numbers in the "Part Number Matrix."
What tools do I need to rebuild the carburetor?
You will typically need a set of screwdrivers (including fine-tipped for jets), wrenches or sockets, pliers, carburetor cleaner, and clean rags. Access to your outboard's service manual is highly recommended.
Are the materials in this kit resistant to modern ethanol-blended fuels?
Yes, all gaskets, seals, and other vulnerable components in this kit are manufactured with ethanol-resistant materials to ensure long-lasting performance and prevent fuel system degradation.
What are common signs my carburetor needs to be rebuilt?
Symptoms include hard starting, rough idling, stalling at low speeds, hesitation upon acceleration, fuel leaks, or black smoke from the exhaust. A rebuild can often restore performance and efficiency.
What does "NSS" mean next to some parts in the box contents?
NSS stands for "No Sierra Substitute," indicating that this is a Sierra-specific component included in the kit that is not sold individually with its own part number.
How often should a marine carburetor be rebuilt?
There is no fixed interval. A rebuild is recommended whenever performance issues arise. For preventative maintenance, consider a rebuild every 2-4 seasons, depending on hours of use, fuel quality, and proper winterization/storage.
