Engine Compatibility
Catalog records associate the 5GH-13440-60 oil-filter reference with selected Yamaha four-stroke outboards, including the following 2017 F25 applications. These examples do not establish compatibility with every Yamaha model or every production year.
| Brand | Model | Rated HP | Stroke | Year | Associated OEM Reference |
|---|---|---|---|---|---|
| Yamaha | F25LA | 25 | 4-Stroke | 2017 | 5GH-13440-60-00 |

- Refer to the engine manufacturer's service procedure and allow the engine and oil to cool as appropriate.
- Place a suitable drain pan beneath the existing filter to catch oil.
- Remove the old filter with an appropriate filter wrench. Check that its sealing gasket has been removed from the mounting surface.
- Clean the filter-mounting surface and inspect it for damage or residue.
- Apply a thin film of clean engine oil to the new filter gasket.
- Install the new filter by hand until the gasket contacts the mounting surface, then tighten it according to the engine service manual.
- Refill the engine with the correct oil and quantity specified by the engine manufacturer.
- Run the engine as directed by the service procedure and check carefully for oil leaks. Stop the engine immediately if a leak is detected.
Maintenance & FAQ
How do I confirm that this filter fits my engine?
Compare the exact engine model and year, the existing filter, and the service-manual part reference. The catalog evidence confirms selected Yamaha F25 four-stroke applications using the 5GH-13440-60 reference, but it does not confirm every Yamaha outboard or every year.
What references can I use when searching?
Search by Yamaha OEM reference 5GH-13440-60 or aftermarket reference Sierra 18-8700. These are references associated with this product listing.
Is this an OEM Yamaha filter?
No. This is an aftermarket replacement oil filter. Yamaha and Sierra names and numbers are used only to identify the applicable reference and are not a statement that this product is manufactured by either company.
When should the filter be replaced?
Replace the oil filter at the interval specified in the engine manufacturer's maintenance schedule. Many service procedures replace the filter during an oil change, but the exact interval depends on the engine model and operating conditions.
What should I do if the new filter leaks?
Stop the engine, verify that the old gasket was not left on the mounting surface, inspect the new gasket and mounting surface, and confirm that the filter was tightened according to the service manual. Do not operate the engine while an oil leak remains.
Safety & Important Information
- Verify the exact model, year, and part reference before purchase.
- Do not assume compatibility from horsepower alone.
- Follow the engine manufacturer's oil type, capacity, installation, and maintenance instructions.
- This is an aftermarket replacement part, not an original Yamaha component.
