When you’re replacing a manifold on one of these motors, you want a part that feels solid in your hands and trustworthy once installed. This Quicksilver exhaust manifold brings that same confidence. It’s built for boaters who know their engines well enough to feel when something’s right, and this part carries that feeling the moment it’s unboxed.\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\"\u003eCast iron exhaust manifold for select V8 MerCruiser engines\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eHot dipped and powder coated for corrosion resistance\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCompatible with port or starboard installation\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eFits 305, 350, and 377 cubic inch engines (1983–2002)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eIncludes gasket for clean, secure sealing\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eQuicksilver part number 860246A15\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\u003cspan data-preserver-spaces=\"true\"\u003eFits MerCruiser sterndrive and inboard V8 engines made by General Motors\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCompatible with 305, 350, and 377 cubic inch platforms\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCommon in performance runabouts, small cruisers, sport boats, and classic cabin boats\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eSuitable for boats operated in freshwater or saltwater with routine maintenance\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\"\u003eThe first thing you’ll appreciate is the weight and balance of the manifold. \u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003eIt has that reassuring heaviness that tells you it’s ready to handle years of heat cycles and vibration.
