Troubleshooting & FAQ
How do I know if this gasket fits my engine?
This gasket is designed for a wide range of Suzuki 4-stroke outboards (25-350 HP) from 2000 to present. The best way to confirm fitment is to check the compatibility table on this page against your engine model and year. You can also match your old part number to the references in our Part Number Matrix.
Why do I need to replace this washer?
This is a single-use crush washer. When tightened, it deforms to create a perfect seal that prevents oil from leaking out of the drain plug. Reusing an old washer can lead to drips and significant oil leaks, risking engine damage.
How often should I replace the drain plug gasket?
It is critical to use a new gasket every time you perform an oil change to guarantee a leak-free seal. Most manufacturers recommend this as standard practice during routine maintenance.
What are the signs of a failing drain plug gasket?
The most common sign is an oil leak or drip from the drain plug area. If you notice fresh oil spots under your engine or a greasy film around the plug, the gasket has likely failed and should be replaced immediately.
Is this part different from the original OEM part?
This is an aftermarket replacement part, not an OEM item. It is engineered to meet or exceed OEM specifications for material, dimensions, and performance, providing a reliable seal at a better value.
OEM vs. Aftermarket?
