This Sierra thermostat kit, 18-3650, is made for Marine Power 3.0L engines. It includes a thermostat gasket, original number 27-47590-1, and a thermostat, original number 59078. No opening temperature is given, so check the rating against your engine's original thermostat before relying on it.
Our take
The kit pairs a thermostat (O.E. 59078) with its gasket (O.E. 27-47590-1), so the seal is replaced along with the thermostat. No opening temperature is stated, so compare the rating with your current one.
