Good To Know

Q: Is this a genuine SeaDoo part? A: This is a quality aftermarket replacement built to OEM specifications, not an original SeaDoo product.

Q: How do I know if my regulator is bad? A: Common signs include a dead battery, dim lights, or erratic tachometer readings; testing voltage output with a multimeter can confirm.

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