Good To Know

Q: How do I know this thermostat fits my boat? A: Confirm your engine is the 1100 series in the 2006 to 2015 SX 210 range and cross-check the OEM number against your original part. Serial number differences can affect fitment, so verify before ordering.

Q: What happens if the thermostat sticks? A: A stuck thermostat can cause overheating or prevent the engine from reaching operating temperature. Replacing it with a correctly rated 140°F unit restores proper coolant regulation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
