Identify your ECM, then order
Use the product grid below to order the matching module. If you want help choosing, send these details together:
- A clear photo of the complete module label and the full part number, including any suffix.
- Photos of the module connectors and the connections on the existing harness.
- The engine tag and serial, plus the boat model and year.
- A description of the problem and any diagnosis already completed.
A boat model, engine family or similar case shape alone does not confirm a module match. Wiring and harness parts require their own application check; browse the PCM GT40 engine parts hub for those listings.
