18-3569 Thermostat Kit for Mercury/Mariner Outboard Motors
Running at the optimum temperature maximizes performance.
A failed or failing thermostat can cause an engine to run outside of its optimum temperature range and adversely affect performance and efficiency. Running at the right temperature can be as simple as replacing the thermostat. Sierra makes sourcing parts for the job easy by packaging the thermostat, gaskets and seal in a kit for an easy out the box installation. Each Sierra part is engineered to meet or exceed Mercury specifications to assure boaters and technicians it will fit right the first time and restore function to OEM specifications.
