Specs At A Glance

Good To Know

Q: Is this an original Sea-Doo part? A: No, it is an aftermarket replacement built to work in place of the factory throttle sensor, and it is not manufactured by Sea-Doo.

Q: Will it need calibration after installation? A: Most throttle-by-wire systems learn the sensor range through a reset procedure, so plan on verifying grip travel or running a scan tool check after fitting.

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