Good To Know

Q: Will this sensor fit my 2018 Sea-Doo? A: It is built for 1630 ACE equipped models such as the RXT, RXP, and XRS 300 from that year. Cross-check your part number against 420664049 before ordering.

Q: Does the sensor need programming after installation? A: No, a camshaft position sensor of this type simply plugs in and reads the camshaft directly. The ECU uses its signal with no special calibration required.

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