Sierra 18-7759 Carburetor Kit for Yamaha 200 HP Outboards, 1990-91

The Sierra 18-7759 Carburetor Kit is a carburetor repair kit engineered for Yamaha 200 HP outboard engines built in 1990-91. Each engine requires one 18-7759 kit to fully rebuild its carburetion system, restoring the carburetor to original operating specification. Sierra builds this kit to OEM quality standards, and it is engineered as a precise, application-specific replacement rather than a generic universal-fit kit, so form, fit, and function match what the outboard originally used.

The kit is the OEM equivalent of Yamaha part number 6K7-W0093-09-00, giving boat owners and marine technicians a reliable source for carburetor rebuild components without going through the OEM dealer channel. It is finished in white to match factory carburetor components. For engines that also need needle valve assemblies, Sierra's 18-7055 needle valve assembly is used at a rate of six per engine and is available as a separate part.

This kit is intended for marine technicians and boat owners performing a carburetor rebuild on a Yamaha 200 HP outboard rather than a full carburetor replacement, and it is sold as a single kit per engine.
