Boat exhaust manifolds are an important part of your boat and maintaining, repairing, or replacing these parts is important to keep your boat running smoothly and avoid additional costly repairs. They should be seen as a regular service item for your boat and when repairs are needed consider Wholesale Marine for your exhaust manifold sets.

Exhaust Manifold sets deal with harsh environments, from the hot exhaust gases and the exposure to water and moist air, which can lead to corrosion. These parts also are under constant vibration either while running or idling which can eat away at the metal and cause leaks.

Whether you are replacing this on your own or having a reputable mechanic replace it when it is time for a replacement for your MerCruiser GM 5.0L/5.7L V8 engines consider this complete OEM exhaust manifold set.
