The Yanmar 128300-13230 is a genuine OEM silencer gasket for select 4LH-series marine diesel engines. Current Yanmar parts references identify this part specifically as GASKET, SILENCER, and Yanmar catalog results place it in the small LH series engine family.
This gasket is used at the intake / silencer connection to help maintain a proper seal and support correct engine airflow. Public parts references also show this gasket used in related gasket-set schematics for 4LH engines, reinforcing its role as a service sealing component rather than a general-purpose gasket.

Parts Desk Insight
Small intake and silencer gaskets are easy to overlook, but they matter because a poor seal can create nuisance issues after service. Replacing the gasket while the assembly is apart is the simple, low-cost way to avoid having to reopen the job later.
