Specs At A Glance

Good To Know

Q: Is this an original Sea-Doo part? A: No, this is an aftermarket temperature sensor that cross-references OEM number 278000194. Always confirm your machine's serial number and existing part before ordering.

Q: Do I need to drain the cooling system to replace it? A: Expect some coolant loss when removing the old sensor, so have a catch pan ready and top off the system afterward. Check for leaks once the engine reaches operating temperature.

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