Maintenance & Troubleshooting
How do I confirm that this kit fits my drive?
Confirm that your drive is an OMC Stringer stern drive within the documented 1964–1986 application range. Match the existing water-pump assembly and primary reference 983218, then verify the exact configuration in the applicable service manual.
