OEM Fit and Reliable Performance

The Mercury-Mercruiser 864547A02 Full Flow Gasket is an OEM part designed for 2002 and newer MerCruiser V6 and V8 engines with dry joint exhaust systems. It provides a secure seal between the exhaust manifold and riser, helping to prevent leaks and maintain consistent exhaust flow.

Whether you’re replacing a worn-out gasket or doing preventative maintenance, this part ensures a proper seal that lasts.

Full Flow Design for Better Cooling

Unlike restricted gaskets, this full flow version allows cooling water to move freely through the joint, improving heat dissipation and engine protection. This open design helps lower exhaust temperatures and keeps your marine engine running cooler under load. Whether you’re cruising or towing, consistent cooling helps maintain peak performance while reducing wear on internal components. Choosing a full flow gasket means better thermal efficiency, longer engine life, and greater reliability every time you hit the water.
