Sierra 18-7911-1 Oil Filter - Replaces Yamaha 5GH-13440-00-00 - Fits F25/T25, F30, F40/F40B, F50, F60, T50, T60 Outboards

The Sierra 18-7911-1 is a spin-on oil filter engineered for modern four-stroke outboard engines, built to meet or exceed the original engine manufacturer's specifications for quality and performance. It is produced in an ISO compliant facility and uses a filter media selected to balance filtration efficiency with oil flow, protecting the engine while preventing oil starvation during use.

Construction centers on a thick steel canister that resists deformation under fluctuating pressure conditions, paired with steel end caps that maintain the filter media's dimensional integrity for the full service life of the filter. The end cap and sealing ring are designed to keep the filter properly mounted and sealed against the engine block, and the housing is epoxy coated for corrosion resistance in a marine environment. An anti-drain back valve is built in to protect the engine at start-up and support long-term engine longevity. The filter uses a 20 mm x 1.5 thread spec.

The 18-7911-1 fits a range of Yamaha four-stroke outboards, including the F25/T25, F30, F40/F40B (International), F50, F60, T50, and T60 models, and is cross-referenced to equivalent Honda, Nissan/Tohatsu, and Yamaha OEM oil filters.
