Sierra Oil Seal for Yamaha Outboard Lower Unit

Sierra oil seals for Yamaha outboard lower units are replacement seals for the gearcase. They keep gear lube in and keep water out of the lower unit. Marine-grade seals like these are commonly used when rebuilding or servicing the driveshaft, propeller shaft, and related gearcase areas.

Key Features:

• Helps keep water out of the gearcase, which protects bearings and gears
• Made for marine use and exposure to water and gear lube
• Backed by Sierra's reputation for aftermarket marine engine parts
