Troubleshooting & FAQ
How do I know if this filter fits my specific engine model?
Please check the "Engine & Model Compatibility" table on this page. Compare your engine's model, HP, and year against the list to ensure a correct fit. Cross-referencing the OEM part number (6D8-WS24A-00-00) is the most reliable method.
What are the signs that my fuel filter needs replacement?
Common symptoms of a clogged or failing fuel filter include engine hesitation, loss of power, stalling, difficulty starting, or rough idling. If you notice these issues, inspect your fuel filter.
How often should this fuel filter element be replaced?
For most recreational boats, it's recommended to replace the primary fuel filter element annually or every 100 hours of operation, whichever comes first. Refer to your Yamaha service manual for specific maintenance intervals.
Is this a complete fuel filter assembly or just the inside element?
This product is the replacement filter element only. It is designed to be installed inside your existing OEM fuel filter housing.
Does this filter include a new gasket or o-ring?
No, this is just the filter element. Gaskets and O-rings are typically part of the filter housing assembly and are not included with the replacement element.
