Over Heat Alarm for Sea-Doo

This over heat alarm is a replacement temperature warning sender that sounds when engine coolant temperature climbs past the safe operating range on 951-powered watercraft, and it cross-references OEM part number 278000978.

Overview

Good To Know

Q: How do I know if this over heat alarm is the right replacement? A: Match the OEM number 278000978 printed on your original sensor and confirm the 2001 RX X 951 application. If your old sender is cracked, corroded, or no longer triggers the warning buzzer, this is the direct fit.

Q: Can I install this temperature sender myself? A: Yes, it threads into the stock temperature port and connects to the existing wiring harness. Drain or clamp the coolant line first, use thread sealant on the sensor body, and test the warning circuit after refilling.

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