🔧 Product Description

Genuine BRP Evinrude Johnson Thermostat-to-Cylinder-Head Gasket - Part Number: 0339044

A genuine BRP thermostat gasket used on selected Evinrude and Johnson two-stroke outboards.

The commonly listed six-digit reference is 339044. The full OEM number is 0339044.

The gasket seals the thermostat housing or cover against the cylinder-head cooling passage, preventing water loss and cross-leakage around the thermostat.
