Westerbeke 30987 Cylinder Head Gasket for Westerbeke Marine Diesel 4-Cylinder - New (NOS)

Westerbeke 30987 Cylinder Head Gasket — New Old Stock, Original Westerbeke Packaging

Application: Genuine Westerbeke service part, OEM part number 30987, for a 4-cylinder Westerbeke marine diesel engine or generator set. The factory label confirms the Westerbeke part number but does not list the engine model, so the specific engine application is not verified — please confirm against your engine model and serial number.

Condition: New / NOS. Still sealed in its original Westerbeke-printed bag with the factory Service Parts label attached. Never installed. Packaging shows yellowing, dust, and light creasing from long-term shelf storage; the gasket itself shows no signs of use.

Four-bore composite head gasket with metal fire rings and steel bore eyelets. One gasket only — no head bolts or additional gaskets included.

Quote is subject to final fitment confirmation by engine/transmission serial number, part number, photos, and supplier availability.

Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase.
