278000194 Temperature Sensor for Sea-Doo SPX 720 1996-1997

Temperature Sensor for Sea-Doo SPX 720

This temperature sensor for Sea-Doo SPX 720 watercraft, OEM cross-reference 278000194, monitors engine temperature and relays that reading to the craft's electrical system so overheating can be detected early.

Overview

This temperature sensor is intended for the Sea-Doo SPX 720 personal watercraft built between 1996 and 1997. It reads engine temperature and sends the signal that the craft's gauge or warning circuit uses to flag abnormal heat. The sensor crosses to OEM 278000194, making it a direct-fit replacement for a failed or inaccurate original unit.

• Delivers a stable resistance signal across the operating temperature range
• Sealed construction resists water and vibration in a marine environment
• Single electrical connector matches the factory harness plug

Fits These Machines

• for Sea-Doo SPX 720, 1996
• for Sea-Doo SPX 720, 1997

On-The-Job Use

• Replacing a failed temperature sensor that reads incorrectly
• Restoring the overheat warning circuit after a cooling system repair
• Routine electrical maintenance on older SPX 720 hulls
• Diagnosing cooling issues during engine service

Specs At A Glance

Good To Know

Q: How do I know if my temperature sensor has failed? A: A failed sensor often causes an inaccurate gauge reading or a false overheat warning. If the gauge sits at one extreme regardless of engine temperature, the sensor is a likely culprit.

Q: Is this sensor a direct replacement for the OEM part? A: Yes, it is cross-referenced to OEM 278000194 and is designed to plug into the factory connector and temperature port. Confirm your model year and engine match before ordering.

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