OMC Evinrude Johnson Check Valve

In OMC Evinrude Johnson outboards, check valves are unidirectional valves that allow fluid flow in one direction only, preventing backflow and ensuring proper system operation. They are crucial for various functions, including preventing water from returning to the cooling system after being pumped, and for proper operation of features like power trim.

Elboration:

Function: Check vales allow fluid to flow in a specific direction, blocking reverse flow.

Purpose in Outboards:

In Evinrude and Johnson outboards, check valves are used in cooling water systems, power trim mechanisms, and potentially other systems.

Example:

A common example is the check valve in the bilge pump system, which prevents water from flowing back into the bilge when the pump is turned off

Types:

while the exact types used in OMC outboards may vary, common check valve types include ball check, swing check, and piston check valves

importance:

Check valves play a vital role in maintaining proper engine cooling, preventing black flow, and ensuring the correct function of various engine systems.
