Good To Know

Q: How do I know my over heat alarm needs replacing? A: If the alarm no longer sounds when the engine overheats or triggers at random, the sensor has likely failed. Testing the circuit and comparing against OEM 278000978 specifications is the safest path.

Q: Does this alarm fit other Sea-Doo models? A: This alarm is associated with the RX 951 platform for the 2000 to 2001 model years. Confirm your model and serial number 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.
