278000965 Temperature Sensor for Sea-Doo GTS 720 1997-2001

Temperature Sensor for Sea-Doo GTS 720

This replacement temperature sensor (OEM cross-reference 278000965) fits 1997-2001 Sea-Doo GTS 720 watercraft and monitors engine coolant temperature so the craft's warning system can react before overheating causes damage.

Overview

This temperature sensor for Sea-Doo GTS 720 is a direct-fit replacement for the factory engine temperature sender used on 720-series Rotax engines. The sensor relays coolant temperature readings to the craft's gauge and overheat warning circuit so you know when the engine is running hot. It is built for personal watercraft owners performing routine maintenance or replacing a failed sender on a 1997-2001 GTS 720.

Specs At A Glance

Good To Know

Q: How do I know if my temperature sensor has failed? A: Common signs include a temperature warning that never activates, erratic gauge readings, or an overheat alarm that triggers when the engine is running cool. Testing the sensor's resistance against factory specs confirms whether replacement is needed.

Q: Does this sensor come with a connector or wiring? A: The listing covers the sensor itself as shown in the title and cross-reference. Reuse the existing connector and wiring from your craft during installation.

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