Installation Notes
- Position a suitable drain pan under the engine oil drain plug.
- Carefully remove the oil drain plug using the correct size socket wrench.
- Remove and discard the old crush washer gasket. Clean any residue from the plug and the sealing surface on the oil pan.
- Place the new gasket over the drain plug threads.
- Re-install the drain plug by hand to prevent cross-threading, then tighten it to the torque specified in your engine's service manual. Do not overtighten.
- Refill the engine with the manufacturer-recommended oil, then run the engine briefly and check for any leaks around the drain plug.
Troubleshooting & FAQ
How do I know if this gasket fits my Suzuki outboard?
The best way to confirm fitment is to check your engine model and year against the compatibility chart above. You can also match your existing part number to the interchange list in the Part Number Matrix.
Is this gasket reusable?
No. This is a single-use crush washer. It is designed to deform when tightened to create a perfect seal. Reusing it will likely result in an oil leak.
How often should I replace this gasket?
You should use a new gasket every time you perform an oil change to ensure a reliable, leak-free seal.
What are the signs of a failing drain plug gasket?
The most common sign is a visible oil drip or seepage from the engine or lower unit drain plug area. If you notice an oil spot under your motor, a worn gasket may be the cause.
OEM vs. Aftermarket?
This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
