Troubleshooting & FAQ
How do I confirm this kit will fit my specific engine?
The most reliable method is to match your engine's model code and year to our Engine & Model Compatibility table. Additionally, comparing your existing part number to those in our Part Number Matrix will help ensure a correct match.
What are the signs that my carburetor needs to be rebuilt?
Common symptoms of a failing carburetor include difficulty starting, rough or erratic idling, stalling at low speeds, poor acceleration, black smoke from the exhaust, and visible fuel leaks around the carburetor body.
How many kits do I need for my engine?
p>This kit services a single carburetor. If your outboard engine has multiple carburetors (e.g., many 3-cylinder models), you will need to purchase one kit for each carburetor to ensure a balanced and complete overhaul.Should gaskets be installed dry or with a sealant?
In most cases, the included gaskets are designed to be installed dry. Applying sealant can cause excess material to squeeze into the carburetor's small passages, leading to blockages and poor performance. Always consult your engine's service manual for specific recommendations.

This listing is for a high-quality aftermarket replacement, not an original equipment manufacturer (OEM) component. It is built to meet or exceed OEM-level specifications using comparable materials.

What is your shipping speed and cost?
We ship orders worldwide, with typical transit times between 5 and 15 days. Standard shipping is free for most regions. If available for your location, expedited shipping options and their costs will be presented at checkout.
What is the warranty and return policy?
This product is covered by a 1-year warranty against manufacturing defects under normal marine use. Should you encounter an issue, please contact our customer support with your order details. Returns are accepted within our standard window for items that are unused and in their original condition. See our full policy page or reach out for detailed instructions.
