How to Identify Your 480HP Model

  • Locate the engine identification plate on the cylinder block or rocker cover; record the model (e.g., D6‑480) and the full serial number. For sterndrive installations, also note the transom shield and drive serial tags.
  • Decode model suffixes: these often indicate drive type (DPH/DPS sterndrive, IPS pod, or inboard), emission family, and revision level.
  • Platform cues: a 4‑stroke common‑rail diesel typically includes a high‑pressure fuel pump, turbocharger, charge‑air cooler, and EVC harnessing.
  • Match by serial: many parts are shared across the D6 family, but items like anodes, impellers, sensors, and belts can vary by serial break and drive family.

FAQs

Are parts interchangeable across different D6‑480 years or drive types?

Many service items are shared within the D6 family, but critical pieces like anodes, impellers, sensors, and drive‑related parts can vary by serial number and by installation (sterndrive, IPS, or inboard). Verify against your engine and drive serials before ordering.

When should the raw‑water impeller be replaced?

As a preventive measure, replace annually or every 200 hours—sooner in sandy/silty or very warm water. Always inspect the old impeller for missing vanes and recover any fragments from the cooling circuit.

How often should gear oil be changed?

Change sterndrive gear oil at least annually or every 100 hours. Inspect for milkiness (water) or metallic sheen (wear). Any contamination warrants immediate service and seal inspection.

What information helps confirm part compatibility?

Provide the engine model (e.g., D6‑480), full engine serial number, drive model/serial (if sterndrive or IPS), and the specific part location or system (fuel, cooling, electrical). Photos of the nameplate and the component are very helpful.
