Specs At A Glance

Good To Know

Q: Is this an original Sea-Doo part? A: No, this is an aftermarket carbon ring cross-referenced to part number 271002109, not an original factory item. It is built to fit the same application.

Q: Do I need to inspect the bellows when replacing this ring? A: Yes, the bellows and support ring work together with the carbon ring to seal the driveshaft, so checking them at the same time is wise. Verify the condition of each 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.
