Troubleshooting & FAQ
How do I confirm this gasket fits my specific Suzuki outboard?
This gasket is designed for Suzuki DF 4-stroke outboard models from 25 HP to 350 HP, year 2000 to present. The definitive way to confirm fitment is to check that your engine's service manual specifies OEM part number 09168-12012 for the oil drain plug gasket.
Why must I replace this crush gasket with every oil change?
The aluminum crush gasket is a single-use component. It is designed to deform (or "crush") when tightened, creating a perfect, tight seal between the drain plug and the oil pan. Reusing an old, compressed gasket will likely result in an improper seal and lead to oil leaks.
What are the signs of a leaking or failed drain plug gasket?
The most obvious symptom is an oil drip or visible seepage from the drain plug area on your engine’s oil pan or lower unit. If you notice any signs of an oil leak, the gasket should be replaced as soon as possible.
Is this aftermarket gasket different from the original Suzuki OEM part?
This aftermarket gasket is manufactured to meet or exceed OEM specifications. It is made from high-quality, corrosion-resistant aluminum to provide the same fit, function, and reliable seal as the original part.
