Current cylinder-head availability

GT40 3-bar cylinder heads are not currently offered for checkout on this site. An old bookmark or listing is not confirmation of current stock. Email support@gt40marine.com with the part you need before making a purchase plan.

Information to gather for a head enquiry

Send your engine identification and the markings on the existing head. If the head is already removed, include any inspection or machine-shop report you have; photographs alone do not establish its condition.

  • Engine tag, boat model and year.
  • Readable casting or part numbers and clear photos of the existing head.
  • The diagnosed repair requirement and any known previous work.

Confirm the replacement before ordering related parts

Ask the supplier or technician responsible for the repair to confirm the exact replacement head and the matching service parts. Do not assume a part marked GT40 or GT40P matches your engine based on the name alone.

Other PCM GT40 parts

The PCM GT40 parts hub contains separate engine-support listings. Check each product against the repair requirement and engine details. Intake, gasket, fuel and tune-up parts are not substitutes for a cylinder head. ECM modules are available to order and are exchange only.
