Troubleshooting & FAQ
How do I confirm that this kit fits my sterndrive?
Verify that your drive is an OMC Stringer sterndrive within the 1964–1986 application range and that the original pump reference is 983218 or its corresponding formatted reference. Also compare the existing pump assembly and mounting arrangement before ordering.
Does this kit fit every OMC sterndrive from 1964–1986?
No. The year range is an application guide, not a guarantee for every drive configuration. Confirm the exact model, drive configuration, original part number, and pump design before installation.
Is this kit for an OMC Cobra drive?
This listing is intended for the documented OMC Stringer application. Do not use it for an OMC Cobra drive unless a reliable application reference specifically confirms that match.
What are common signs of a worn water pump?
Possible symptoms include overheating, reduced cooling-water flow, poor water circulation at idle, visible impeller damage, damaged seals, or leakage around the pump assembly. Inspect the complete pump whenever the impeller is replaced.
Should the pump be serviced as a complete assembly?
Inspect the housing, plate, impeller, seals, gaskets, and O-rings together. Replace damaged or heavily worn mating parts rather than installing a new service component against a scored or distorted surface.
Is this an OEM part?
No. This is an aftermarket replacement water pump kit intended to replace the listed OMC application reference.
Safety & Important Information
- Verify the model, year, drive configuration, original part number, and component arrangement before ordering.
- Do not rely on horsepower or year alone to establish fitment.
- Use the manufacturer’s service manual for removal, installation, torque values, and testing procedures.
- Never operate the engine without an adequate water supply.
- Professional installation is recommended when servicing the sterndrive or cooling system.
