Thermostats for Outboard Engines – Regulate Engine Temperature

Thermostats for Outboard Engines – Regulate Engine Temperature

The thermostat is a crucial part of your outboard’s cooling system, ensuring the engine quickly reaches optimal operating temperature. A faulty thermostat can cause overheating or a too-cold engine, affecting performance and engine life. In our thermostats for outboard engines category, you’ll find OEM and aftermarket parts for brands like Suzuki, Yamaha, Mercury, Honda, Tohatsu, and Evinrude.

Our thermostats are made from high-quality, marine-grade materials that withstand heavy use. During maintenance, the thermostat is often replaced together with the impeller, impeller housing, and gaskets to ensure a fully functional cooling system.

  • Thermostats for all major outboard brands
  • High-quality, marine-grade materials
  • Regulates engine temperature for optimal performance
  • Suitable for both 2-stroke and 4-stroke engines

Replace the thermostat according to manufacturer recommendations or at the first sign of malfunction to avoid overheating and engine issues.
