Product Details

The Sierra 18-0275 is a precision-engineered replacement O-ring designed for Yamaha outboard motors and sterndrive applications. This critical seal component is used in the lower unit gearcase assembly to prevent water intrusion and maintain proper lubrication.

Key Features:

  • Direct replacement for Yamaha OEM part number 93210-97M55-00
  • Manufactured to meet or exceed original equipment specifications
  • Compatible with Yamaha 2-stroke V6 engines from 1984 and later
  • Fits Yamaha 4-stroke outboards including 150HP, 175HP, and 200HP models
  • Also compatible with Yamaha sterndrive 3.0L, 4.3L, 5.0L, and 5.7L engines
  • Essential component for lower unit seal kits and gearcase maintenance

This O-ring seal is a critical wear item that should be replaced during lower unit service, gearcase rebuilds, or whenever seals show signs of deterioration. Sierra marine products are engineered for reliability and long service life in demanding marine environments.
