🔧 Product Description

Genuine Quicksilver Water Intake Elbow Gasket - Part Number: 27-8M0109475

A genuine Quicksilver gasket for the water-inlet elbow or tank-cap joint in selected modern Mercury MerCruiser raw-water cooling systems.

The gasket seals the removable water-inlet component within the Bravo sea-pump hose and transom water-supply assembly. Correct sealing prevents water leakage and suction-side air entry that could reduce seawater-pump output.
