Good To Know

Q: How do I know if my bellow needs replacing? A: Cracks, hardening, or water weeping around the water box joint are the usual signs the bellow has aged out. Replacing it promptly helps protect the power valve assembly.

Q: Is this an original Sea-Doo part? A: This is a replacement bellow made to cross-reference OEM part 420260721, not an original factory item. Confirm your model and serial number before ordering.
