It is one of those things you barely think about when it is working right, but you feel it immediately when something is off. A smooth trim lets you settle the bow exactly where you want it—lifting over chop, easing into shallow water, or finding that perfect running angle on a long stretch of open water. Mercury Marine part 8M0021648 brings back that confidence. It is a small but essential end cap that keeps the entire hydraulic system sealed, steady, and responsive. When you know your equipment is working the way it should, the whole day on the water just feels easier.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan data-preserver-spaces=\"true\"\u003eKey Features\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eGenuine Mercury Marine hydraulic trim and tilt cylinder end cap\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eDesigned for select 110–300 horsepower Mercury and Mariner outboards\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eDurable aluminum alloy construction for strength and corrosion resistance\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003ePrecision-machined for a tight, secure hydraulic seal\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eBuilt to factory specifications for proper trim system pressure and response\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eEasy installation with \u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003ecommon\u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003e shop tools\u003c\/span\u003e\n\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 select 110–300 horsepower Mercury and Mariner outboards across multiple lines:\u003c\/span\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eTwo-stroke EFI\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eSport XS and Pro XS\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eDFI and DTS\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eMarathon, SeaPro, and ProMax\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eJP, XB, XR6, Magnum III\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003e2.5L and 3.0L platforms\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eSelect Verado models\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCommon on bass boats, bay boats, offshore center consoles, flats skiffs, pontoons, and runabouts\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eIdeal for boats frequently trimmed during rough-water running, shallow entries, and trailering\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\"\u003eWhen a trim system starts to weaken, you feel it long before you see it.
