Good To Know

Q: Is this an original Sea-Doo part? A: This is an aftermarket gasket that cross-references OEM number 420950840, not a factory original. Q: How many gaskets do I need for a pump rebuild? A: Check your service manual for the exact count, as some housings use more than one sealing surface.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
