Specs At A Glance

Good To Know

Q: Do I need to replace the chain at the same time? A: It is good practice to inspect the cam chain for stretch or wear when replacing the tensioner guide, and replace both if wear is found. Reusing a worn chain with a new guide can shorten service life.

Q: Is this an original Sea-Doo part? A: No, this is an aftermarket replacement intended to fit Sea-Doo RXT X 300 1630 models. Always confirm the part number and fitment against your machine 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.
