Sierra Oil Filter 18-7954-1, Yamaha N26-13440-00-00, Fits F200/F225/F250 4.2L & F300/F350 V8 Outboards

The Sierra 18-7954-1 is a spin-on oil filter engineered for Yamaha outboard engines, built to keep engine oil clean and free of contaminants that cause premature wear. It uses an anti-drain-back valve to prevent oil from draining out of the filter when the engine is off, so oil pressure builds quickly on startup instead of leaving critical components running dry for those first few seconds. The filter housing is constructed of metal and is epoxy coated for corrosion resistance, an important feature for filters mounted in the humid, salt-exposed marine engine bay.

This filter is designed to meet or exceed the performance of the original equipment part it replaces, and is intended for the extreme demands of high horsepower marine engines. It threads on with a 3/4 x 16 fitting for a secure, leak-resistant seal. The 18-7954-1 fits a range of Yamaha F-series outboards using the N26-13440-00-00 oil filter, including 4.2L four-cylinder models and V8 models, making it a common replacement filter for scheduled oil changes and maintenance on these engines.
