SouthMarine Carburetor Repair Kit for Mercury 8HP & 9.9HP — OEM 8M0044576 Replacement with Gaskets & Needles

SouthMarine's Carburetor Repair Kit 8M0044576 restores worn Mercruiser/Quicksilver outboard carburetors used on Mercury 8HP and 9.9HP engines.

If your small Mercury outboard is running rough, flooding, or suffering from poor idling, the root cause is often deteriorated carburetor gaskets, needles, seats and seals. This comprehensive SouthMarine kit is built to replace the OEM Mercruiser Quicksilver part number 8M0044576 and includes the common consumables needed to bring those carburetors back to proper function without replacing the whole carburetor. The kit is organized to match the original component layout so installation is straightforward for a DIY mechanic or marine technician.

Which engines and carburetors does this repair kit fit?

The SouthMarine kit is specifically designed for Mercruiser/Quicksilver carburetors used on Mercury 8HP and 9.9HP outboards. It mirrors the OEM parts and dimensions of part number 8M0044576, making it a direct replacement set for compatible carb models.

• Compatible with Mercury 8HP and 9.9HP outboard engines
• Made to replace Mercruiser Quicksilver OEM 8M0044576
• Contains gaskets, O-rings, needles, seats and common carburetor consumables
• If uncertain, provide your engine serial number to confirm fit

How does replacing these parts improve engine performance?

Worn gaskets and seals let air or fuel leak, which upsets the carburetor’s calibrated fuel/air mixture. Installing fresh seals, needles and seats restores sealing surfaces and valve function, improving idle stability, throttle response, and reducing fuel seepage.

• Stops vacuum and fuel leaks that cause rough idling
• Restores correct float and needle seating for stable fuel level
• Improves throttle response by ensuring proper mixture control
• Helps prevent fuel overflow and hard starting conditions

What’s included and what tools or skills are needed to install it?

The kit supplies the typical removable parts you’ll swap during a carburetor rebuild: gaskets, O-rings, needle valves, seats and other rubber/plastic components that wear with age. Basic mechanical skills and common hand tools are sufficient for removal and replacement, but cleaning and inspection of metal parts is recommended.

• Includes OEM-matching gaskets, O-rings, needles and seats
• Requires basic tools: screwdrivers, wrenches, small pliers, carb cleaner
• Carburetor cleaning and inspection advised before reassembly
• If unsure, a marine mechanic can perform the rebuild quickly

How do I confirm this is the right kit for my engine?

Check your carburetor or the engine’s parts list for Mercruiser/Quicksilver part number 8M0044576. If you can’t locate that number, the most reliable method is to provide your engine serial number when ordering so fitment can be verified.

• Match to Mercruiser Quicksilver OEM 8M0044576 for direct replacement
• Provide engine serial number if there’s any doubt about fit
• Compare the kit parts visually to your old components before installation
• Contact seller or technician with photos of your carburetor for help

This SouthMarine repair kit is intended for boat owners, DIYers and marine technicians who maintain small outboard Mercury engines. It’s ideal when symptoms point to aging carburetor consumables—such as fuel leaks, unstable idle, poor acceleration or difficult starting—but the carburetor body itself is serviceable. If the carburetor has major corrosion, cracked castings, or internal damage, a full carburetor replacement or professional rebuild may be required. For routine maintenance and economical repair of Mercruiser/Quicksilver carburetors on 8HP and 9.9HP Mercury outboards, this kit delivers the OEM-matching parts to restore reliable operation.
