Good To Know

Q: Does this housing include the impeller or wear ring? A: This listing covers the jet pump housing only, so impeller, wear ring, and related internal parts are ordered separately. Reusing or replacing those components depends on the condition of the existing pump.

Q: How do I confirm this housing matches my craft? A: Check the OEM number stamped or listed for the pump on the machine and compare it to 99999-04523-00. Model year and serial number ranges can affect fit, so verify 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.
