Sierra 18-0324 Carburetor to Manifold Gasket - Replaces Mercury 27-151724, 27-15172-3, 27-93214

The Sierra 18-0324 is a carburetor to manifold gasket for Mercury outboard engines, designed to create a reliable seal at the joint between the carburetor and the intake manifold. This round gasket is manufactured to meet or exceed the fit, form, and function of the original equipment part it replaces, giving boat owners and marine technicians a dependable option for carburetor service and rebuild work. Sealing this joint properly is important for maintaining correct air-fuel mixture and preventing vacuum or air leaks that can cause rough idling, hesitation, or hard starting.

The Sierra 18-0324 cross-references directly to Mercury OEM numbers 27-151724, 27-15172-3, 27-15172, and 27-93214, and is also interchangeable with GLM 32770 and Mallory 9-60048, making it easy to source as a replacement no matter which part number appears on your existing gasket or repair manual. It is a lightweight, single-use gasket intended to be installed once and replaced whenever the carburetor is removed for service, ensuring a fresh, leak-free seal each time the joint is broken.
