Quicksilver 19183Q02 Lower Unit Gear Lube Drain Fill Screw Seal Gasket

The Quicksilver 19183Q02 drain screw gasket is an essential seal for maintaining the lower unit gear lube system on MerCruiser sterndrives and Mercury/Mariner outboard motors. This gasket creates a reliable seal between the drain/fill screw and the lower unit housing, preventing gear oil leaks and contamination.

Key Features:

• Designed for use with 3/8-16 drain/fill screws on MerCruiser and most Mercury/Mariner outboards
• Includes 4 gaskets per package for multiple service intervals
• OEM Quicksilver quality ensures proper fit and sealing performance
• Not compatible with Verado models or Mercury/Mariner outboards of Japanese origin

Regular replacement of these gaskets during gear lube service helps maintain the integrity of your lower unit and prevents costly damage from oil leaks or water intrusion. These gaskets should be replaced every time the drain and fill screws are removed for routine maintenance.
