Specifications

Opens at
160 F

This is Quicksilver's thermostat kit for MerCruiser sterndrive engines built on General Motors V6 and V8 blocks. It is a 160 F thermostat and comes with the seal, so the part and its gasket arrive together. It covers 1998 and newer engines with closed cooling, the setup that calls for a 160 F thermostat. It is made to Mercury Marine original equipment specifications.

Our take

The 160 F rating is the point of this kit: it is for closed-cooling GM V6 and V8 engines from 1998 on, so a thermostat with a different opening temperature is the wrong part. The seal is in the kit, so there is no second part to chase when the old thermostat comes out.
