Sierra 18-7916 4-Cycle Outboard Oil Filter
A heavy-duty spin-on oil filter built to OEM specifications for selected Johnson and Evinrude 4-stroke outboards. The 18-7916 uses high-efficiency filter media, a heavy-wall steel canister with corrosion-resistant epoxy coating, and an anti-drain-back valve to prevent dry starts between oil changes. The 3/4"-16 thread pitch is the key fitment identifier when cross-referencing similar outboard oil filters.

Service Interval
Replace at every scheduled oil change per your engine manufacturer's maintenance guide — typically every 100 hours or once per season. Regular replacement prevents contaminants from circulating through the lubrication system and accelerating wear.
Installation Notes
- Remove the old filter and confirm its sealing gasket comes away with it — a double-gasket is one of the most common causes of oil leaks after a filter change
- Clean the filter mounting surface thoroughly
- Lightly lubricate the new filter's gasket with clean engine oil before installing
- Install per your engine manufacturer's procedure — typically hand-tight plus 3/4 turn
- Run the engine briefly and inspect for leaks at the filter seat before returning to service

Parts Desk Insights
Quickest fitment check: If your engine uses Johnson/Evinrude OEM filter 434839, the Sierra 18-7916 is the confirmed match. The 3/4"-16 thread is a useful secondary identifier when comparing similar outboard oil filters side-by-side.
Most common install mistake: Leaving the old gasket stuck to the engine block. Always look for it — a double-stacked gasket will cause an immediate oil leak at startup.
