Product Details
This aftermarket oil filter is designed for selected Yamaha outboard applications using the Yamaha oil-filter references 3FV-13440-00-00, 3FV-13440-20-00 or 3FV-13440-30-00. It is also identified by the aftermarket reference Sierra 18-7902.
The filter is a spin-on replacement intended to support routine engine-oil service. Because Yamaha fitment can vary by model, year and exact configuration, compare the part number and filter mounting specifications with your engine service information before ordering.
- Aftermarket replacement oil filter for selected Yamaha outboards.
- Spin-on installation for straightforward routine maintenance.
- 20 mm x 1.5 thread specification as listed for the Sierra 18-7902 reference.
- Supplied as one oil filter; this is not a kit.

- Place a drain pan beneath the filter and drain the engine oil according to the owner's or service manual.
- Remove the old filter with a suitable filter wrench and clean the filter mounting surface.
- Confirm that the old gasket has been removed. Apply a thin film of clean engine oil to the new filter gasket if recommended for the filter design.
- Install the new filter by hand until the gasket contacts the mounting surface. Tighten it only to the engine or filter manufacturer's stated instructions; do not over-tighten.
- Refill with the correct oil type and quantity specified for the engine.
- Run the engine and inspect the filter and mounting area for leaks. Stop the engine, allow the oil to settle, and recheck the oil level.
