Sierra 18-3535 is a Mercury thermostat with a 130° temperature rating, which is the key figure to compare with your engine's specification. It is listed for use with the 18-3606 thermostat kit. Compare the number on your old thermostat and its rating with your engine's specification before swapping it in, and treat the rating as the main figure to check.
Our take
The 130° rating is what defines this Sierra 18-3535 thermostat, so on a Mercury engine the check is whether 130° is what your engine calls for. It is also listed for use with the 18-3606 thermostat kit, which gives a second number to cross-check.
