This is the Sierra 3633 thermostat kit, part 18-3633, listed for Mercury. The maker gives no other details and points you to the Sierra catalog for complete application information, so use that to confirm it matches your engine.
Our take
It is sold as a thermostat kit rather than a lone thermostat, under Sierra number 18-3633 and listed for Mercury. Sierra sends you to its catalog for complete applications, so confirm your engine there.
