Maintenance & FAQ

How do I confirm compatibility?

Match the original filter reference and the complete engine details—brand, horsepower, 2-stroke configuration, model, and year—to the information above. Do not rely on horsepower alone.

Is this a complete fuel-filter assembly?

No. This listing is for one replacement fuel filter element. The housing and other fuel-system components are not included unless specifically stated above.

What symptoms may indicate a restricted fuel filter?

Possible symptoms include hard starting, hesitation, rough running, stalling, or reduced power. These symptoms can have other causes, so inspect the complete fuel system before replacing parts.

How often should the filter be replaced?

Follow the maintenance interval in the applicable Yamaha service documentation. Replacement may also be necessary when contamination, water, restricted fuel flow, or visible filter damage is found.

Is this an OEM Yamaha part?

No. This is an aftermarket replacement intended for the listed applications. Yamaha and Sierra names and reference numbers are used only to identify the applicable replacement relationship.

Safety & Important Information

  • Fuel is flammable. Keep the work area ventilated and away from ignition sources.

  • Do not install this part on a 4-stroke engine based only on horsepower or model-family similarity.
  • Do not operate the engine if any fuel leak is present.
