Sierra's 18-3606 is a replacement thermostat kit for Mercury engines, with a temperature rating of 130° F. It is designed to meet OEM specifications. The kit holds two 18-3535 thermostats and two 18-3675 thermostat cover gaskets, so the gaskets come with the thermostats in one box.
Our take
This kit supplies two 18-3535 thermostats and two 18-3675 cover gaskets, so a pair is renewed together along with the seals. The 130° F rating is the figure to compare with what your engine calls for.
