Installation Guide

1. Position a suitable drain pan under the engine's oil drain plug.
2. Using the correct wrench, carefully loosen and remove the drain plug, allowing the old oil to drain completely.
3. Inspect the drain plug and its threads for any signs of damage or wear. Clean the plug thoroughly.
4. Remove the old, used crush washer from the drain plug and discard it. Do not reuse old gaskets.
5. Slide the new crush gasket (09168-12012) onto the drain plug.
6. Reinstall the drain plug with the new gasket by hand, then tighten it to the manufacturer's recommended torque specification. This ensures a tight seal without stripping the threads.
7. Refill the engine with the correct type and amount of new outboard oil as specified in your owner's manual.
8. Start the engine and let it run for a few minutes, carefully checking for any oil leaks around the drain plug area.

Troubleshooting & FAQ

Q: How do I confirm this gasket fits my Suzuki engine?
A: This gasket fits most Suzuki 4-stroke outboards from 25 HP to 350 HP, model years 2000 to present. Please check the "Compatible Engine Models" table on this page to verify your specific model and year. It directly replaces OEM part number 09168-12012.

Q: How often should I replace the oil drain plug gasket?
A: For a reliable, leak-proof seal, it is strongly recommended to replace the crush gasket every time you change the engine oil. Reusing an old, compressed gasket significantly increases the risk of oil leaks.

Q: What are the signs of a failing drain plug gasket?
A: The most common sign is an oil leak or drip originating from the drain plug area after an oil change. If you notice fresh oil on the ground below your engine or a sheen of oil on the lower unit housing, the gasket may be compromised and should be replaced.
