Fresh spark plugs help the engine fire quickly and evenly, even after long storage. Updated filters keep fuel and oil free of contaminants, adding protection you can actually feel when the motor is pushing a loaded boat against wind and tide. And because every part is built to Mercury’s exact standards, installation is straightforward, and the fit is secure and confidence-building.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eWhether you fish shallow flats at dawn, run gear for work, or cruise slow along the shoreline, a complete 300-hour service brings back the ease and satisfaction of using an engine that just works.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eWhy Buy OEM\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eGenu\u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003eine Mercury Marine part built to match factory specs\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eLong-lasting materials that stand up to freshwater and saltwater use\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eMore cost-effective over time than mixing aftermarket components\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eEnsures precise fitment with no unexpected surprises\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eHelps maintain engine reliability, resale value, and total ownership confidence\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eWhen\u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003e you’re taking care of a small outboard you rely on day after day, OEM parts are simply the practical choice.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eFAQ\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eQ1: Which engines does this kit fit?\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e It fits Mercury 8hp and 9.9hp FourStroke Command Thrust models within the listed serial number range.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eQ2: What makes this kit better than aftermarket options?\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e Every component is engineered to Mercury’s original standards, ensuring proper fit and long-term durability.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eQ3: How do I confirm this is the right kit for my engine?\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e Match your serial number to the range 0R042475–1R279944, or check your owner’s manual.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eQ4: Can this kit be used in both fresh and saltwater?\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e Yes, all included components are designed for harsh marine environments.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eQ5: Is installation easy for most boat owners?\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e If you’re comfortable performing routine service, you’ll find this kit straightforward and well-organized.\u003c\/span\u003e\u003c\/p\u003e","brand":"Mercury","offers":[{"title":"Default Title","offer_id":46935248077091,"sku":"8M0120867","price":195.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/7410\/9475\/files\/8M0120867_Main.jpg?v=1760631371"},{"product_id":"mercury-8-9-9-standard-gearcase-only-300-hour-service-kit-8m0120837-s-n-0r042475-above","title":"Mercury – 300 Hour Maintenance Kit | FourStroke Service Package | Complete Engine Care Components | 8M0120837","description":"\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eMercury 8-9.9 HP EFI – 300 Hour Maintenance Kit | FourStroke Service Package | Complete Engine Care Components | 8M0120837\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eOverview\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eThere’s a special kind of pride that comes from owning a small FourStroke Mercury outboard.
