As part of our commitment to quality and customer satisfaction, Marco Engines implements a core return policy to ensure the seamless exchange of remanufactured engines and parts.

Core Return Timeframe: The old core must be received within one calendar year from the date of invoice to qualify for credit. Failure to return the core within this timeframe will result in the replacement being considered sold outright, and it will be removed from our records of engines eligible for deposit credits.

Refund Process: Refunds for core deposits will be issued to the original payment method upon successful inspection of the returned core. Please note that any return shipping charges incurred by Marco Engines will be deducted from your core deposit.

Core Inspection Criteria: To be eligible for credit, the returned core must meet specific criteria:

  1. The core casting must match that of the purchased engine.
  2. It must be free of cracks or poor welds, with rusty castings and damaged crankshafts not acceptable.
  3. The core must include all parts provided with the replacement engine.

Core Deposit Considerations: Please ensure the returned core is packaged securely to prevent damage during transit. We recommend using the original packaging whenever possible to facilitate safe return.
