The Quicksilver 79953Q04 Lower Unit Gear Lube Drain and Fill Hole Screw and Seal is a replacement fastener and seal set designed for use during gear lube service on Quicksilver lower units. Built with a corrosion-resistant construction, it stands up to constant exposure to water and moisture, making it a dependable choice for marine engine maintenance where standard hardware tends to break down over time.
This drain and fill hole screw and seal is used whenever gear lube is changed or checked in the lower unit, a routine task for outboard motor upkeep. A worn or damaged screw and seal can allow gear lube to leak out or let water intrude into the housing, leading to costly gear case damage. Replacing this component with an OEM-fit Quicksilver part helps maintain a proper seal, supports consistent lubrication levels, and reduces the risk of moisture contamination inside the lower unit during regular maintenance intervals.
This part suits boat owners, marine mechanics, and outboard motor technicians who perform their own lower unit gear lube changes and want a proper-fitting replacement screw and seal. Anyone searching for a Quicksilver lower unit seal, outboard gear lube drain screw, or marine engine drain plug seal will find this component a practical addition to their maintenance parts inventory, supporting reliable performance of the lower unit over time.
