      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.
