Sierra 18-7911-1 4-Cycle Outboard Oil Filter
Part Number: Sierra 18-7911-1 (SKU: 47-79111)
Brand: Sierra
UPC: 808282000000
The Sierra 18-7911-1 is a marine-grade spin-on oil filter for selected Yamaha, Nissan/Tohatsu, and Honda 4-stroke outboards. Built with a heavy-wall steel canister, epoxy-coated exterior, high-efficiency filter media, and an anti-drain-back valve, it's engineered to meet or exceed OEM specifications for 4-cycle outboard lubrication service.
Key Features
- Heavy-wall steel canister construction
- Epoxy-coated exterior for corrosion resistance in saltwater environments
- High-efficiency filter media meets or exceeds OEM filtration standards
- Anti-drain-back valve retains oil in the filter after shutdown — prevents dry starts
- Meets or exceeds original equipment specifications
Compatible Applications
- Yamaha F15, F25, F30, F40, F50, F60 4-stroke outboards
- Yamaha F75, F90, F100, F115 4-stroke outboards
- Nissan/Tohatsu MFS-series 4-stroke outboards (cross-references 3R0-07615-0 family)
- Honda 4-stroke outboards using compatible OEM filter references (15400-PFB-007 / 15400-ZW4-003)
Fitment Note: Confirm engine model, horsepower, year, and existing OEM filter number before ordering. The strongest quick-match references are the Yamaha 5GH-13440-series numbers or Nissan/Tohatsu 3R0-07615-0.

Parts Desk Insights
This is a high-volume filter for Yamaha F-series owners doing routine oil changes — the 5GH-13440 cross-reference family covers a wide range of popular models from F15 through F115. A common question from customers is whether it also fits Honda; it does on select applications via the 15400-PFB-007 / 15400-ZW4-003 cross-reference, but always confirm against the model and year. The anti-drain-back valve is worth calling out to customers who store their outboards seasonally — it keeps the filter primed so there's no oil-pressure lag on first startup.
