Troubleshooting & FAQ
How do I confirm fitment?
Match the original gasket’s part number and dimensions, then confirm the exact Suzuki model, year, stroke, and serial-number range in the applicable service or parts documentation. The DF-series applications shown on this page are identification guidance and should not replace model-specific verification.
Why should the gasket be replaced?
A crush gasket deforms as it is tightened to form the seal. Reusing a deformed washer can contribute to seepage or leakage at the drain plug.
Where is this gasket installed?
It is intended for a compatible engine-oil drain-plug or lower-unit drain-plug application. The correct location depends on the specific outboard and the manufacturer’s service procedure.
What are common signs of a sealing problem?
Oil or lubricant drops, wetness, or a greasy film around the drain plug may indicate an improperly seated gasket, incorrect torque, damaged sealing surfaces, or another service issue. Stop and inspect the installation before operating the engine.
Is this an OEM part?
This listing is for an aftermarket replacement gasket. Suzuki 09168-12012 and the other numbers shown are manufacturer or aftermarket reference numbers used for identification and compatibility comparison.
Does the package include a drain plug?
No. The package includes one replacement crush gasket only. A drain plug, lubricant, tools, and installation hardware are not included unless separately stated.
Safety & Important Information
- Verify the part number, dimensions, model, year, stroke, and serial-number range before purchase and installation.
- Use the torque value and service procedure specified for your outboard.
- Do not operate the engine if a drain-plug leak is present.
- This is an aftermarket replacement component, not a Suzuki-branded OEM part.
- Professional installation is recommended when the correct application or torque specification is uncertain.
