Shipping & Returns

Shipping

At Marco Engines, we offer comprehensive worldwide shipping, catering to both residential and commercial addresses within the United States. Please note that certain products may have shipping restrictions, and some items cannot be shipped to international destinations.

Upon placing an order, we’ll provide you with estimated shipping and delivery dates based on the availability of your items and the shipping options you select. Shipping date estimates may vary depending on the chosen shipping provider and will be displayed on the shipping quotes page.

Flat rate shipping charges and free shipping apply to deliveries within the 48 Contiguous United States exclusively.

If you receive a damaged item or have any concerns about the condition of your delivery, please do not sign for it upon receipt. Instead, refuse the shipment to allow us to address your concerns with the shipping company promptly. Once an item is signed for, you acknowledge satisfaction with the shipment and confirm that there is no evident damage. This is particularly crucial for LTL shipments, such as engines. If an engine arrives improperly positioned or inadequately secured to a pallet or crate, refuse delivery and contact us immediately.

Returns Policy

New, unopened Engine Kits may be returned within 30 days of delivery for a full refund (excluding any applicable Affirm Restocking Fee). Items must be returned in their original condition, with intact packaging. Return label fees are the responsibility of the customer.

Parts manufactured by Marco Engines, such as Crankshafts and Cylinder Heads, are subject to a limited return/warranty window of 30 days.

Typically, refunds are processed within four weeks from the time your package is received by the return shipper. This timeframe includes the transit time for the return to reach us (5 to 10 business days), processing time upon receipt (3 to 5 business days), and the time required for your bank to finalize the refund request (5 to 10 business days). However, refunds are often completed more expeditiously than this.

To initiate a return, simply login to your account, access the order via the “Complete Orders” link under the My Account menu, and click the Return Item(s) button. You’ll receive email notifications regarding the status and eligibility of your refund.

Please note that returns are not accepted for Engines, Stroker Engines, Stroker kits, custom builds, High-Performance engines, or any items necessitating machining.

Affirm Restocking Fee

Engines and items purchased with an Affirm financing option that are canceled or returned are subject to an 8% restocking fee, calculated based on the total purchase price.
