Good To Know

Q: Is this carbon ring a genuine Sea-Doo part? A: This is a replacement carbon ring made for Sea-Doo applications and is not an original manufacturer part. It is referenced by part number 272000770 for identification.

Q: Should the sealing surfaces be inspected when replacing the carbon ring? A: Yes, the mating ring and boot should be checked for wear or damage whenever the carbon ring is replaced. Replacing worn sealing surfaces together helps prevent repeat water intrusion.
