FAQs
Q1: How do I verify if this H2D turbocharger fits my 6CTA Marine Engine?
Please check the nameplate on your current turbocharger for the part number 3802886 or 3538623. Since marine turbos are very specific to horsepower ratings (e.g., 450HP vs 430HP), confirming the 7-digit Cummins part number is essential. If you are unsure, please provide your Engine Serial Number (ESN) for a free fitment audit.
Q2: Is this turbocharger suitable for saltwater environments?
Yes. We use high-grade ductile iron housings and provide a protective finish specifically for the harsh, humid, and salty environments of marine engines. Every unit is built to withstand the unique corrosion and thermal challenges of offshore operation.
Q3: Does this turbocharger require an external wastegate?
This H2D model is typically non-wastegated (Standard Marine Configuration). It is a "drop-in" replacement that matches your factory setup for the 6CTA engine, including all mounting flanges and oil line connections.
Q4: What type of warranty do you provide for marine orders?
As a direct manufacturer with nearly 30 years of experience, we stand behind our quality and provide full technical support for boat owners and marine mechanics 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.
