When you're running long distances, trolling all afternoon, or navigating tight channels at idle, it’s the oil system that keeps everything cool, smooth, and predictable. This filter gives boaters a sense of calm — the kind that comes from knowing their engine is being cared for each second it’s running. It’s one of those small parts that quietly supports every great day on the water.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eK\u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003eey Features\u003c\/span\u003e\n\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eScrew-on oil filter designed for Mercury FourStroke engines\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eSuperior M-Pleated filtration media removes fine contaminants\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eHeavy-duty housing with corrosion-resistant coating\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eMaintains steady oil pressure for cleaner operation\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eOEM filter engineered for long-term reliability\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cspan data-preserver-spaces=\"true\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eFits Mercury FourStroke:\u003c\/span\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003e75–115 horsepower outboards\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003e1\u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003e50 horsepower EFI FourStroke outboards\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003e105 horsepower EFI Jet models\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eIdeal for runabouts, pontoons, bay boats, bass boats, and multi-species hulls\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cspan data-preserver-spaces=\"true\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eThis filter keeps your oil clean and your engine running strong. \u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003eThe M-Pleated media captures fine debris that can slip past cheaper filters, giving you more consistent lubrication and smoother operation across the entire power range.
