Troubleshooting & FAQ
Which Suzuki models does this gasket fit?
This gasket is designed for Suzuki DF200, DF225, and DF250 outboards from 2004–2014, as well as DF300 series models from 2007–2014. Please check the compatibility table for specific model years and details.
How can I tell if my motor mount cover gasket is failing?
Signs of a failing gasket include visible oil leaks or seepage around the motor mount cover, a drop in oil pressure, or engine performance issues. A visual inspection for cracks, brittleness, or compression in the old gasket during maintenance is also recommended.
Is this part identical to the OEM Suzuki gasket?
While this is an aftermarket part, it is manufactured to meet or exceed OEM specifications for fit, form, and function. It is made from a comparable rubber/paper composite material to ensure a durable and reliable seal.
Can I reuse my old gasket or apply sealant to it?
No. Gaskets are designed for single use as they crush to create a seal. Reusing an old gasket, even with sealant, will likely result in leaks. Always replace with a new gasket when servicing the component.
