FAQs

Q1: How do I verify if this RHC61W turbocharger fits my Yanmar engine? 

Please check the nameplate on your current turbocharger for the Yanmar part number 119195-18031 or the IHI code VC240080. Since Yanmar marine engines have very specific cooling jacket requirements, matching the OEM part number is the most reliable way to ensure a correct fit.

Q2: Is this turbocharger specifically designed for marine (saltwater) environments? 

Yes. This unit is a dedicated marine turbocharger. It features a water-jacketed cooling system (Water Cooled) to help manage engine room temperatures and use specialized materials to resist the corrosive effects of salt air and high humidity.

Q3: What are the primary causes of turbo failure in Yanmar marine engines? 

The most common causes are saltwater ingestion (through the exhaust system) and oil starvation at high RPMs. We recommend inspecting your exhaust risers/mixing elbows and ensuring your oil lines are clear of carbon buildup during the installation of this new unit.

Q4: What type of warranty do you provide for marine commercial users? 

We understand that marine engines are often used for extended periods at high loads, which is why we stand behind our quality with full technical support for boat owners and marine workshops worldwide.

Q5: Do you provide worldwide shipping? What is the delivery timeframe? 

We ship globally via premium carriers like DHL, FedEx, and UPS, as well as sea freight for bulk orders. In-stock items are typically dispatched within 24–48 hours. Express delivery to North America and Europe usually takes 5–7 business days.
