Good To Know

Q: How often should an oil filter cover O-ring be replaced? A: Replace it at every oil and filter service, or whenever the cover is removed, since a flattened ring will not seal reliably again. Keeping a spare on hand avoids downtime.

Q: Is this an original Sea-Doo part? A: No, this is an aftermarket O-ring made to cross-reference OEM number 420850500 for the 1503 engine. Confirm your model and year 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.
