How to match a PCM GT40 replacement part
- Record the engine identity. Photograph the engine tag and note the boat model, engine serial and rotation details where applicable.
- Read the existing part. Copy its complete part number and photograph the label, connections and mounting points. A similar-looking part is not a confirmed match.
- Compare the individual listing. Check the stated application, included components and current availability. A complete assembly and an individual service component are separate purchases.
- Resolve missing details before ordering. Send the photos and part number together so GT40 can review the application without repeated requests for information.
