When the water is calm and the dock is just ahead, you want your engine to respond with quiet confidence—no hunting, no stumbling, no surprises. That’s the kind of reliability this Mercury Marine part delivers. The 8M0181068 Idle Air Control Valve helps your engine breathe exactly the way it should, giving you the peace of mind that comes from a boat that feels ready, steady, and completely under control.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eKey Features\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eRegulates idle airflow for smooth, stable rpm under all conditions\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003ePrecision-machined construction built for longevity\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eD\u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003eesigned for MerCruiser MPI engines using the ECM 555 system\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eEnsures clean idle transitions with accurate air metering\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eOEM-calibrated performance for consistent response\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eMay require additional gaskets or seals depending on installation\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eFits MerCruiser 3.0-liter MPI sterndrive and inboard engines\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCompatible with MerCruiser V6 MPI engines\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eF\u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003eits MerCruiser V8 MPI engines including 305, 350, and 496 cubic inch models\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eDesigned specifically for engines equipped with the ECM 555 control module\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eSuitable for runabouts, cruisers, bowriders, workboats, and multipurpose sterndrive vessels\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eW\u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003ehen an idle air control valve starts to weaken, you feel it right away—rough idle at the dock, sudden rpm drops when shifting into gear, and an uneasy sense that something isn’t quite right.
