Return, Refund & Cancellation Policy
Marine Inboard Specialists
Last updated: July 23, 2026
Marine Inboard Specialists supplies marine diesel engines, marine generators, transmissions, propulsion components and replacement parts. This policy explains when a product may be returned, how to request a return and when a refund will be issued.
1. Return period
Eligible products may be returned within 30 calendar days of delivery.
To begin a return, you must contact us within this 30-day period and obtain a Return Merchandise Authorization number. Returns sent without prior authorization may be refused.
2. Return eligibility
To qualify for a return, the product must be:
- New, unused and uninstalled.
- In its original packaging.
- Complete with all accessories, manuals, documentation and supplied components.
- Free from damage, alteration, programming or modification.
- Accompanied by the order confirmation or invoice.
- Returned with the manufacturer’s serial number and identification labels intact.
Engines, generators and components that have been installed, operated, filled with fluids, connected to a vessel, commissioned, programmed or modified cannot be returned as unused products.
3. Non-returnable products
The following products are not eligible for voluntary return:
- Special-order, custom-built or customer-configured products.
- Products clearly identified as final sale before purchase.
- Installed, used, operated or modified products.
- Electrical or electronic components with opened or broken safety seals.
- Products missing serial numbers, identification plates or supplied components.
- Opened lubricants, fluids, chemicals or other consumable products.
- Products damaged after delivery through incorrect storage, handling, installation or use.
A product will only be treated as non-returnable because it is special-order, customised or final sale when this condition was clearly disclosed before the order was placed.
These exclusions do not apply when we supplied the wrong product or when an unused product arrived damaged or defective.
4. How to request a return
Contact our customer support team within 30 calendar days of delivery:
Email: support@marineinboardspecialists.com
Telephone: +1 (214) 937-0535
Please provide:
- Your order or invoice number.
- The product name and serial number.
- The reason for the return.
- Photographs showing the product and its packaging, when requested.
If the return is approved, we will provide the RMA number, return instructions and applicable shipping information.
Products must not be returned until written authorization has been issued.
5. Return shipping
For an approved voluntary return, the customer is responsible for:
- Return shipping costs.
- Suitable packaging.
- Freight insurance.
- Tracking and delivery confirmation.
The customer remains responsible for the product until it is received at our approved return location.
If we supplied the wrong product or the product arrived damaged or defective, Marine Inboard Specialists will arrange or reimburse reasonable return shipping using a method approved by us.
Do not arrange expedited or international return freight without our written approval.
6. Restocking fee
A 20% restocking fee applies to approved voluntary returns of correctly supplied products.
The restocking fee does not apply when:
- We supplied an incorrect product.
- The product arrived damaged in transit.
- An unused product is confirmed to have a manufacturing defect.
- Applicable law requires otherwise.
Original shipping charges are non-refundable unless the return results from an error by Marine Inboard Specialists or a confirmed defect in the supplied product.
If a returned product is incomplete or damaged beyond what is reasonably necessary to inspect it, the refund may be reduced to reflect the missing components or loss in value. We will notify the customer before making such a deduction.
7. Inspection and refunds
All returned products are inspected after delivery to our approved return location.
Once the return has been inspected and approved, we will issue the refund to the original payment method within 10 business days.
Your bank or payment provider may require additional time to display the refund in your account.
If a return does not meet this policy, we will contact you and explain why the refund cannot be approved. The customer may be responsible for the cost of returning an ineligible product.
8. Damaged, defective or incorrect products
Inspect your shipment as soon as it arrives.
Visible freight damage, missing packages or incorrect products should be reported within 3 business days of delivery. Where possible, note visible damage on the carrier’s delivery receipt and retain the original packaging.
Contact:
Email: support@marineinboardspecialists.com
Telephone: +1 (214) 937-0535
Please include photographs of:
- The external packaging.
- Shipping labels.
- The damaged or incorrect product.
- The product serial number.
- The carrier’s delivery documentation.
After reviewing the claim, we may arrange a replacement, repair, return or refund, depending on the circumstances and product availability.
The three-business-day reporting request helps us submit a carrier claim and does not remove any rights provided by applicable law.
9. Order cancellations
Standard-stock orders may be cancelled for a full refund if the cancellation is received before the order has been shipped or committed to freight preparation.
Special-order, configured or custom products may become non-cancellable after allocation, configuration or manufacturer processing begins. Any non-refundable cancellation condition will be disclosed to the customer before payment or order confirmation.
To request cancellation, contact us immediately with your order number. Sending a cancellation request does not confirm cancellation. We will provide written confirmation of the order’s status.
10. Exchanges
We do not offer general product exchanges.
Customers may return an eligible product under this policy and place a separate order for the replacement product. If we supplied an incorrect or defective product, we may provide a replacement as part of resolving the claim.
11. Manufacturer warranty claims
Manufacturer warranty coverage is separate from this return policy.
Products that develop a fault after installation or operation may require inspection and diagnosis under the applicable manufacturer’s warranty. Warranty approval is determined according to the manufacturer’s conditions and may require inspection by an authorised service technician.
Marine Inboard Specialists can provide available purchase documentation and direct the customer to the relevant warranty procedure. Please review the applicable warranty information before installing or commissioning the product.
12. International returns
International customers must request an RMA within 30 calendar days of delivery.
For voluntary international returns, the customer is responsible for:
- Return freight.
- Freight insurance.
- Export and import documentation.
- Customs clearance.
- Duties, taxes and brokerage charges.
- Compliance with carrier and destination-country requirements.
Original freight charges, customs duties, import taxes and brokerage fees are generally non-refundable because they are paid to carriers, brokers or government authorities.
If an international shipment contains an incorrect, damaged or defective product, contact us before arranging return freight. We will provide written instructions and determine the appropriate resolution.
If a shipment is refused because the customer did not pay disclosed duties, taxes or customs fees, the customer may be responsible for return freight, customs charges and the applicable 20% restocking fee.
Mandatory consumer rights in the customer’s country are not excluded by this policy.
