Temperature Sensor for Sea-Doo
This temperature sensor for Sea-Doo watercraft, OEM cross-reference 278000965, monitors engine coolant temperature so the cooling system can be watched for overheating.
Overview
This temperature sensor for Sea-Doo replaces the factory sending unit on Challenger 1800 800 models built from 1997 through 1999. The sensor reads coolant temperature and sends that signal to the gauge or warning system, giving the operator an early sign of an overheating engine. It is intended for owners performing routine replacement or restoring a neglected cooling circuit on their sport boat.

Good To Know
Q: Will this sensor plug into my existing wiring harness? A: It is built to the 278000965 cross-reference, so it uses the factory connector style for the listed Challenger 1800 800 years. Verify your harness and sender threads before ordering.
Q: Do I need to drain the coolant to replace it? A: Since the sensor threads into a coolant passage, expect some coolant loss when it is removed. Drain or clamp the circuit first and refill with the correct marine coolant afterward.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
