OMC Evinrude Johnson Seal Valve

In OMC Evinrude and Johnson outboards, a seal valve, often part of pressure release assembly, is a component that helps maintain pressure within the engine's cooling system. This valve, typically a globe or butterfly valve, ensures proper sealing to prevent fluid leaks and maintain optimal engine operation.

Here's a more detailed look:

Purpose: 

The seal valve, often part of a larger pressure release valve assembly, is responsible for preventing lacks in the cooling system and maintaining correct fluid pressure.

Function:

When the engine is running, the valve's seal prevents coolant from escaping, while also allowing for controlled pressure release when necessary.

Types: 

OMC and Johnson outboards may use various seal valve designs, including globe valves and butterfly valves, depending on the engine model and specific application.

Maintenance:

Regular inspection and replacement of damaged or worn seal valves are essential to ensure proper engine cooling and prevent potential issues.
