Sierra 18-7049 Needle Valve, Replaces Yamaha 61N-14392-00-00, 62Y-14392-00-00, 6L2-14392-00-00 and Mercury 8095701

The Sierra 18-7049 Needle Valve is a carburetor needle valve built for marine outboard applications. It is a direct replacement for Yamaha outboard needle valves 61N-14392-00-00, 62Y-14392-00-00, and 6L2-14392-00-00, as well as Mercury Marine 8095701, making it a straightforward swap when a carburetor is leaking, flooding, or not holding fuel level correctly. The valve is constructed of metal with a rubber tip and uses a threaded inlet connection with two ports, matching the fitment and function of the original equipment part it replaces. Each package includes one needle valve, sized precisely at 0.39 x 0.39 x 0.39 inches, so it seats correctly in the carburetor bowl without modification. Sierra manufactures this part to meet or exceed the specifications of the original equipment it is designed to replace, giving boat owners and marine technicians a reliable option for carburetor rebuilds and fuel system maintenance. Because a worn or damaged needle valve is a common cause of flooding, rough idle, or hard starting in outboard engines, keeping a correct-fit replacement like the 18-7049 on hand is useful for routine carburetor service.
