Choosing parts for your PCM GT40 engine
Find the part for the repair you are planning, then match it to your engine and existing hardware. This guide covers engine-support parts; ECM checkout is currently paused.
PCM GT40 owners choosing replacement or service parts
Compare the options
| Option | Best for | Before ordering | Notes |
|---|---|---|---|
| Intake manifold and gaskets | A diagnosed replacement or planned service | Engine and existing part | Compare the exact application and part details. An engine-family name alone does not establish that a manifold or gasket fits. |
| Fuel, tune-up, starter and charging parts | Replacing the specific part your repair requires | Part number and application | Check the individual listing and the existing part. Include mounting, connector or rotation details when they apply. |
| ECM review | Checking an existing module after diagnosis | Checkout currently paused | Send the module label, part number and connector photos for review. Do not buy an ECM as a diagnostic trial. |
Start with the part your repair requires
Use a diagnosis or service plan to identify the part you need. The PCM GT40 parts hub groups intake, fuel, tune-up, starter and charging listings so you can compare the relevant products in one place. A shared category is not a fitment guarantee.
Match the engine and the existing part
Read the individual product application before ordering. If a part number or application is unclear, contact GT40 with the details you have.
- Send the engine tag and serial information, plus the boat model and year.
- Include the existing part number and clear photos of the part and its mounting or connectors.
- For a starter or another rotation-specific part, include the stated rotation information; ask for help if it is unclear.
Check the complete requirement for the job
Review the product page for included components, current price and availability. Confirm any separately required parts before ordering. Do not assume that a related product is included or required for your repair.
ECM ordering status
ECM checkout is currently paused. For an existing module review, send the label, part number and connector photos to support@gt40marine.com. A replacement module should not be used to test an unresolved fault.
Common questions
Does this guide cover a complete PCM GT40 engine?
This guide covers engine-support parts. If you need a complete engine assembly, contact GT40 to discuss that requirement before choosing individual parts.
Will a listed part fit every PCM GT40 or Ford 351W application?
Do not assume it will. Match the exact engine, existing part number and relevant mounting or connector details to the individual product listing before ordering.
How do I choose a part when the fault has not been diagnosed?
Complete the diagnosis before selecting a replacement. Send GT40 the engine details, symptoms and any test results when asking about a product; a product listing cannot establish the cause of the fault.
Can I order an ECM through this guide?
ECM checkout is currently paused. Contact support with the existing module label, part number and connector photos for review.
