OEM Replacement Oil Fill Screw Plug Seal 311598 for select OMC, Johnson and Evinrude outboard gearcases, including the SST45 racing gearcase . Designed to seal the lower unit oil fill screw and help prevent gear oil leaks and water intrusion.
Ideal for routine gearcase service, lower unit oil changes, and drain/fill screw maintenance.
The Oil Fill Screw Plug Seal 311598 is an OEM sealing washer used on select OMC, Johnson and Evinrude outboard gearcases, including the SST-45 Racing Gearcase.
This seal fits the lower unit oil fill screw and helps create a secure seal between the screw and the gearcase housing. A worn, compressed, damaged, or missing seal can allow gear lubricant to leak out or water to enter the lower unit.
Replacing the oil fill screw seal during routine gearcase maintenance is a simple and inexpensive step that can help protect internal lower unit components and maintain proper lubrication.

Recommended Service
Inspect the oil fill and drain screw seals whenever changing lower unit gear oil. Seals that appear flattened, cracked, brittle, torn, or excessively compressed should be replaced before reinstalling the screw.
For best results, verify your engine model, gearcase configuration, and original part number before ordering to confirm compatibility.
