Product Details

The Sierra 18-3549 is a 120-degree marine engine thermostat designed as a direct replacement for Mercury and Mariner outboard motors. Maintaining optimum engine temperature is critical for maximizing performance and fuel efficiency, and a failed thermostat can cause an engine to run outside its ideal operating range.

Key Features:

  • 120°F temperature rating for precise cooling system control
  • Engineered to meet or exceed OEM specifications
  • Compatible with Mercury/Mariner 6, 7, 8, 9.9, and 15 HP outboards (serial A197112 and later)
  • Direct replacement for Mercury Marine part number 14586
  • Also replaces GLM 13120, Mallory 9-43014, and Sears 14586

Sierra marine thermostats are manufactured to deliver reliable OEM fit and function, giving boaters and marine technicians confidence in their cooling system repairs. This thermostat is a cost-effective solution to restore proper engine temperature regulation and prevent overheating or inefficient operation.

Fair price and quick delivery.
