Add to CartThe Mercury-MerCruiser 27-62386001 Thermostat Gasket is a replacement sealing component for compatible Mercury and MerCruiser cooling system applications. This gasket is used where part number 27-62386001 is specified by the Mercury-MerCruiser parts diagram or service manual.

Service Note: Follow your Mercury-MerCruiser service manual for thermostat housing removal, gasket surface cleaning, thermostat inspection or replacement, gasket placement, fastener torque, and final cooling system leak checks.
Fitment Note: Thermostat gasket fitment should be verified by engine model, serial number, thermostat housing style, parts diagram, and existing gasket part number before ordering. Please confirm this thermostat gasket is correct for your Mercury or MerCruiser application before purchasing.
