🔧 Product Description

Genuine BRP Evinrude Johnson Thermostat Cover O-Ring - Part Number: 0331188

A genuine BRP rubber O-ring used to seal the thermostat cover or cooling-water cover on selected Evinrude and Johnson two-stroke outboards.

The O-ring prevents cooling water from leaking around the thermostat-cover joint and maintains the pressure required to circulate water through the cylinder-head cooling passages.
