When replacing a critical marine engine part like a manifold, you want a dependable option. At Diesel Pro Power, we sell aftermarket Cummins manifolds that exceed original equipment manufacturer (OEM) specifications. These products expand on the Cummins reputation for reliability and performance to hold up to the tough conditions that manifolds face during operation. As you look for the right manifold for your engine, you can count on us to make the process simple from start to finish.

When to Replace Your Manifold

Because of its use in redirecting and cooling exhaust gases, a marine manifold needs to stay in good operating condition for the engine's health. If you notice any issues with your manifold or engine, you should consider inspecting it or consulting a mechanic right away. Some of the factors that might contribute to a need for replacement include:

  • Age and operating conditions: Your manifold's age, frequency of use and operating conditions all impact its wear. If you use your boat in salt water, your manifold will wear down more quickly than it would in fresh water. Remember to inspect your manifold every other year or so at minimum to check for any signs of damage.
  • Corrosion: If your boat has more intense corrosion than average, it might spread to the manifold. Check for stray current corrosion from faulty wiring or equipment.
  • Water in the cylinders: If your engine has difficulty starting, runs roughly or burns white smoke, you could have water in your cylinders. These signs could indicate that a damaged manifold has allowed water to seep in.
