High-Performance RHC61W Turbocharger for 4LH-STE Marine Engines

• Designed for Marine Engines: This RHC61W turbocharger is developed for 4LH-STE diesel engines and related 4LH-series marine configurations. It provides the airflow required for stable engine performance during cruising, acceleration and continuous marine operation.
• Built for Marine Working Conditions: Marine engines often operate under steady load for extended periods. This turbocharger is designed to maintain consistent boost pressure during long cruising, harbor maneuvering and high-load propulsion, helping the engine deliver dependable power when needed.
• Reliable Wastegate Control: The RHC61W uses a wastegated turbocharger design to help regulate boost pressure across the engine speed range. This supports stable engine operation and helps protect the turbocharger and engine from excessive boost during changing load conditions.
• Direct Replacement Configuration: The mounting structure, oil connections and air passages are designed for the original 4LH-STE turbocharger application. This allows the unit to be used as a replacement without unnecessary changes to the existing exhaust and intake arrangement, subject to fitment confirmation.
• Suitable for Marine Service and Refit Projects: This turbocharger is suitable for marine repair shops, boat refit projects and engine maintenance programs. It can be used for replacing worn or damaged turbochargers on vessels powered by 4LH-series diesel engines.
