OMC Evinrude Johnson washers are specialized components used in their outboard motors and sterndrives, serving various purpose like sealing, distributing load, and preventing damage. 

Here's a summer of their description and common characteristics:

Types:

Flat washers: Used to distribute the load of a fastener.

Thrust Washers: Act as a bearing surface for rotary applications, often made of materials with low friction coefficients like steel, bronze, or plastic. They are essential for protecting the propeller shaft and gearcase.

Other specialized washers: Including O-ring washers and those for specific applications like manual tilt systems.

Materials:

Stainless steel: Known for its durability and corrosion resistance, frequently used in these washers.

Rubber: Used in some washers.

Other materials: Including metal alloys, carbon steel, iron, and fiber depending on the specific application

Applications: 

Propeller installation: Thrust washers are crucial for protecting the gearcase from damage caused by propeller thrust.

Sealing: Some washers, like O-ring washers, are used to create seals to prevent leakage

General fastening: Flat washers are used in various fastening applications throughout the engine

Manual tilt systems: Specific washers are used in the manual tilt mechanism.

Note: The specific type, material, and dimensions of an OMC Evinrude Johnson washer will vary depending on the particular engine model and application. Always consult your engine's parts manual for the correct washer specifications.
