Quicksilver 864549A02 Exhaust Manifold Gasket – Dry-Joint Block-Off for MerCruiser V6 & V8 2002 and Newer

The Quicksilver 864549A02 exhaust manifold gasket is an original block-off gasket for MerCruiser V6 and V8 engines (Sterndrive & Inboard) built from 2002 onwards with Dry-Joint exhaust systems. This gasket specifically blocks certain water passages in the exhaust manifold/exhaust elbow transition and is used when the manufacturer or the respective engine variant provides for a controlled, limited water flow.

Dry-Joint systems reliably separate exhaust gas and cooling water to prevent water from entering the engine. A correctly fitting block-off gasket is therefore crucial for a functioning cooling system, optimal engine temperatures, and the longevity of the exhaust system.

The gasket exactly matches the strict OEM specifications of Mercury Marine. It guarantees high temperature resistance, a perfect fit, and a permanently secure seal. Installation and precise model assignment are carried out according to the specifications in the user or service manual.
