Good To Know

Q: Will this sensor fix a false overheat warning? A: It can, if the original sensor is reading incorrectly, since this unit provides the temperature signal the warning system relies on. Confirm the wiring and connector are also in good condition before replacing.

Q: Does this sensor require a gasket or sealant? A: Many installations use a sealing washer or thread sealant to prevent coolant leaks at the mounting point. Check the factory service procedure for the 1994 Sea-Doo XPI 650 before installation.

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