CRITICAL: You must inspect the pallet before signing the delivery receipt. If you see visible damage, you must note "DAMAGED" on the driver's paperwork or refuse the shipment. If you sign a clean receipt, we cannot file a claim, and the return may not be accepted.

Returns are accepted within 90 days if the engine is unused and uninstalled. Please note that a 15% restocking fee applies to all non-defective returns to cover handling and testing costs. Return shipping is the customer's responsibility.
