Back pressure from exhaust manifolds reduces performance. The function of exhaust manifolds is crucial because they direct waste products (exhaust gases) away from the engine so that it can draw in more air to burn. The headers give each engine cylinder its tube, enabling the gases to depart without generating back pressure.
The Marine Exhaust Manifold is essential for maintaining the engine system's top performance. Hot exhaust gases are carried away from the machine by exhaust manifolds and risers on inboard engines which are substantial metal castings. Exhaust manifolds typically last 6 to 8 years however, the use of saltwater may shorten life expectancy to three years, and up to 20 years more might be added to the life expectancy with moderate use of freshwater. It is crucial to replace the exhaust manifold right away. Do not hold off replacing the exhaust manifold because it plays such a salient part in your boat's exhaust system.
