      MerCruiser Exhaust Manifold

      Every boater should know that corrosion is the enemy of many boat engine parts. Even those that are sealed, such as an exhaust manifold, are not protected from damage by outside elements. As part of any sound maintenance program, Wholesale Marine recommends that you have this vital engine part inspected and, when worn, have it replaced to avoid costly engine repairs or even a rebuild.

      Need to Replace Your MerCruiser Exhaust Manifold? Let Us Help!

      MerCruiser exhaust manifolds are among the most reliable on the market. Models that have manifolds that are cooled by the engine’s fresh water/antifreeze coolant mixture will last indefinitely but still require routine maintenance. Should your MerCruiser Exhaust Manifold require replacement, know that we are your source for every part the task requires. From MerCruiser OEM Exhaust Elbows to Sierra Exhaust Boots to an entire MerCruiser OEM Exhaust Manifold, hardware, hose barbs, risers, drain taps, and gaskets, Wholesale Marine even carries the hardware and tools to ensure you’ll get the job done right.

      Shop Wholesale Marine for Mercruiser 4, 6, and 8-cylinder exhaust manifolds and risers.
