It is a direct replacement for Sierra 18-7911-1 and multiple OEM part numbers, and is manufactured in an ISO\/TS 16949 certified facility to meet or exceed OEM specifications.\u003c\/p\u003e\n\n\u003cp\u003eThe 20-micron cellulose filter element captures large contamination particles before they can reach lubricated engine components, while maintaining low restriction for full oil flow. An epoxy-coated canister resists corrosion in the marine environment, and a thicker body wall improves structural integrity under pressure. Heavy-duty end cap seals reduce the risk of leakage, and an anti-drain back valve prevents oil from draining out of the filter when the engine is off — ensuring immediate oil pressure on start-up.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eFull-flow spin-on oil filter\u003c\/li\u003e\n\u003cli\u003e20-micron cellulose filter element\u003c\/li\u003e\n\u003cli\u003eAnti-drain back valve — maintains oil in filter between starts\u003c\/li\u003e\n\u003cli\u003eEpoxy-coated canister for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eThicker body wall for improved structural integrity\u003c\/li\u003e\n\u003cli\u003eHeavy-duty end cap seals\u003c\/li\u003e\n\u003cli\u003eManufactured in an ISO\/TS 16949 certified facility\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eReplaces:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSierra: 18-7911-1\u003c\/li\u003e\n\u003cli\u003eHonda: 15400-PFB-007\u003c\/li\u003e\n\u003cli\u003eNissan \/ Tohatsu: 3R0-07615-0\u003c\/li\u003e\n\u003cli\u003eYamaha: 5GH-13440-00-00\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eBest Use Case:\u003c\/strong\u003e A direct service replacement for the oil filter on compatible Honda, Yamaha, and Nissan\/Tohatsu outboard engines during routine oil changes.
