Sierra 18-7909 Honda Outboard Oil Filter, Replaces 15400-PLM-A01PE, 15400-POH-305PE, 15400-ZJ1-004

The Sierra 18-7909 is a spin-on oil filter built for Honda outboard engines, designed to provide reliable filtration in the demanding marine environment. It features an anti-drain-back valve that keeps oil in the filter between starts, so lubrication reaches critical engine components immediately on startup rather than after a delay. The canister is made of heavy-wall steel with an epoxy coating for corrosion resistance, helping the filter withstand exposure to moisture and salt air over its service life. Inside, a high-efficiency filter media meets or exceeds OE filtration performance, capturing contaminants to help protect engine internals from premature wear. The filter uses a 20mm x 1.5 thread spec and is a universal fit across the Honda outboard applications it cross-references to. It is backed by Sierra's warranty and built from premium-grade materials intended to excel in extreme marine conditions. This filter is a straightforward drop-in replacement wherever the listed Honda part numbers are specified, making it a convenient option for scheduled oil changes and routine maintenance on compatible Honda outboard engines.
