Troubleshooting & FAQ
How do I confirm this filter fits my outboard?
The best method is to match the part number from your old filter to one of the OEM or aftermarket numbers listed in our Part Number Matrix. If you cannot find a part number, use the Engine & Model Compatibility table to find your engine's make, model, and year.
What are the signs of a clogged fuel filter?
Common symptoms include engine hesitation, sputtering, difficulty starting, rough idling, or a loss of power, especially at high speeds. Since this filter has a transparent body, you may also see visible debris or discoloration inside.
How often should this fuel filter be replaced?
As a general rule, replace your outboard fuel filter annually or every 100 hours of operation, whichever comes first. If you frequently use fuel from portable tanks or operate in harsh environments, more frequent changes may be necessary.
Can this filter be cleaned and reused?
No, this is a disposable inline filter. Attempting to clean it can damage the internal filter media and is not recommended. It should be replaced with a new unit.
What happens if the filter is installed backward?
Installing the filter against the flow arrow will severely restrict or block fuel flow, leading to poor engine performance or failure to start. Always ensure the arrow points from the fuel tank towards the engine.
