Yamaha - Lower Case Packing - Lower Unit Sealing Component - 6EE-G5315-00-00

Overview

Packing like this is one of those parts you don’t see once everything’s buttoned up, but it’s doing important work the whole time. I’ve seen lower units come apart because of leaks that started with worn or flattened packing. It helps keep water out and oil where it belongs, especially in smaller gearcases. When it’s fresh and installed right, the lower unit stays sealed and protected.
