Performance & Practical Benefits

The 810929004 Gasket Set is small but essential. When the carburetor’s gaskets begin to harden or leak, it can throw off your air-fuel balance — leading to hard starts, rough idle, or poor throttle response. Replacing them restores proper performance and fuel efficiency.

Each gasket in this kit is precision-cut for a tight, factory fit that prevents vacuum leaks and fuel seepage. The materials resist swelling, shrinking, and breakdown from today’s ethanol-blended fuels, giving you long-term reliability. Whether you’re doing a light tune-up or a full carb rebuild, this OEM set keeps your engine running smooth and dependable.

Why Buy OEM

Mercury’s OEM gasket sets are built with the right materials, cut to exact dimensions, and tested to perform under marine heat and vibration. Aftermarket gaskets often use cheaper materials that degrade quickly or don’t seal evenly — a risk you can’t afford on the water.

When you use a genuine Quicksilver kit, you know each gasket will align perfectly, torque down evenly, and hold tight through every season. It’s precision and peace of mind in one small package — exactly what you expect from OEM Mercury Marine parts.
