Troubleshooting & FAQ
How do I know if my thermostat is failing?
Common signs include engine overheating, the engine not reaching normal operating temperature (running too cold), or erratic readings on your temperature gauge. A failed thermostat can stick open or closed, disrupting coolant flow.

Yes, this part is confirmed to fit Evinrude FICHT models from 200HP to 250HP manufactured between 2000 and 2005.
What is the specified operating temperature?
This thermostat is designed to begin opening at 133°F (56°C) to regulate engine temperature. While some sources may list it as 130°F, 133°F is the confirmed rating.
Why are two seals included in the package?
The kit includes two seals to ensure you have all necessary components for a complete and reliable installation. It is critical to replace old seals to prevent leaks and ensure a proper fit.
