Good To Know

Q: How do I know this seal fits my watercraft? A: Match the OEM number 420850948 and your model year against your parts diagram, and check your engine serial number before ordering. Q: Should I replace other pump parts at the same time? A: When the pump is apart for a seal replacement, inspecting the impeller, bearings, and housing for wear is a smart step.

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