Sierra Front/End Plate Gasket 18-2832-1-9, Replaces 27-48043-1, Fits Manifolds 18-1958-1 & 18-1962-1

The Sierra 18-2832-1-9 is a front/end plate gasket used to seal the front plate assembly on compatible exhaust manifolds in marine engine applications. It is made from a stainless steel infused graphite material, chosen for its superior compressibility, which helps the gasket conform to mating surfaces and maintain a reliable seal under the heat and vibration typical of an inboard exhaust system.

This gasket fits the port and starboard caps of manifolds 18-1958-1 and 18-1962-1, and is designed for use with front plate 18-4009. It is also included as a component within the 18-8512 mounting kit, so owners assembling or servicing that kit already have this gasket included, while those replacing the gasket individually can order it under its own part number. As a Sierra part, it is built to correspond with the OEM cross-reference 27-48043-1 for straightforward identification when sourcing a replacement.
