Product Description
Mercury MerCruiser Quicksilver 27-802691 is the small gasket used at the carburetor drain-screw position on specified Mercury and Mariner FourStroke outboards. It is a separate service gasket from the larger float-bowl perimeter gasket.
Key Features
- OEM carburetor gasket, full reference 27-802691.
- Located with the float-bowl drain screw in the applicable carburetor diagram.
- GTIN: 745061264625.
Engine Compatibility
Verified uses include Mercury 8 / 9.9HP 209 cc carbureted FourStroke assemblies and specified 13.5 / 15HP carbureted FourStroke assemblies. The 9.9HP 209 cc carburetor diagram for serials 0R676746 and above lists it next to drain screw 809578005.
Fitment and Installation
Match the carburetor model and drain-screw callout. Similar number 8026911 is a different gasket shown elsewhere in older carburetor diagrams. Inspect the drain screw and seating face, replace a damaged or compressed gasket, and check for fuel leakage after service.
