The exhaust manifold is one of those unsung heroes — it keeps the engine breathing cleanly and running cool, day after day, season after season. With Mercury Marine part number 866178T01, you’re getting a piece of hardware that feels solid in your hands and even more reassuring once it’s installed. Whether you’re pushing through chop or easing down to idle after a long run, there’s something comforting about knowing your exhaust system is built to last and won’t surprise you when you least expect it.\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\n\u003cspan data-preserver-spaces=\"true\"\u003eD\u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003eirect replacement exhaust manifold for \u003c\/span\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eMerCruiser 8.1L and 8.2L non-EC engines\u003c\/span\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eHeavy-duty cast iron construction for durability\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCoated internally and externally for corrosion resistance\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eDesigned to handle high heat, pressure, and marine moisture\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eEngineered to maintain proper exhaust flow and cooling balance\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\"\u003eF\u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003eits \u003c\/span\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eMerCruiser 8.1L\u003c\/span\u003e\u003c\/strong\u003e\u003cspan data-preserver-spaces=\"true\"\u003e and \u003c\/span\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003e8.2L\u003c\/span\u003e\u003c\/strong\u003e\u003cspan data-preserver-spaces=\"true\"\u003e non-EC sterndrive and inboard engines\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCommon on performance cruisers, larger bowriders, cabin boats, tow-sports setups, and offshore-style hulls\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eWorks for both freshwater and saltwater environments\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCompatible with Bravo-series sterndrives and various inboard configurations\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\"\u003eA well-built manifold changes the way your whole engine feels.

Mercury designs theirs to withstand extreme heat cycles, moisture exposure, and the unique vibration profiles of marine big-block engines. Aftermarket versions might look similar, but they rarely match the internal cooling passages and metal density Mercury uses. With OEM, you’re protecting your engine, your time, and your wallet long-term.
