REFUND POLICY

Last updated 2026-08-14

30-day return window

You may return unused items in original packaging within 30 days of delivery for a refund to the original payment method. Email support@gt40marine.com with your order number before sending anything back so we can issue a return authorization and the correct return address.

PWC LAB Link 30-day trial guarantee

You may connect, power on, and try PWC LAB Link. If it is not for you, email support@gt40marine.com within 30 days of delivery for return authorization. Return the complete Link kit, including the Link hardware, included harness, and included accessories, for a refund to the original payment method.

Customer-caused damage, modification or tampering, missing parts, and returns after 30 days are not covered. The buyer pays return shipping unless the return is due to our error, a defect, or damage in transit.

Items not eligible for return

Installed parts, except PWC LAB Link returned under its 30-day trial guarantee above
Electrical parts that have been installed or powered on — ECUs, alternators, starters, switches, sensors — except PWC LAB Link returned under its 30-day trial guarantee above
Special-order items and custom-tuned ECUs flashed to a specific VIN
Items returned without prior return authorization
Items returned after the 30-day window

If you're unsure whether a part will fit before you install it, email us with your year/make/model/HP and we will check the application.

Return shipping

For returns not caused by our error (wrong item shipped, defect, damage in transit), the buyer pays return shipping. We recommend a tracked, insured carrier — we cannot refund items that go missing in return transit. For returns caused by our error, we email a prepaid return label.

Refund processing

Refunds are issued within 3–5 business days of receiving the returned item and confirming it meets the applicable return conditions. Refunds go back to the original payment method. Bank/card posting times vary by issuer and are usually 1–3 business days after we issue the refund.

Warranty

All GT40 Marine branded parts carry a 1-year manufacturer warranty against defects in materials and workmanship. Warranty coverage does not apply to damage from improper installation, tuning beyond manufacturer specifications, race use, or normal wear. Email us with your order number and a description of the issue to start a warranty claim.

ECM checkout and new ECM lifetime-warranty add-on sales are currently paused for product-truth certification. Warranty rights for existing orders remain governed by the terms in effect when the order was placed; contact support with the order number for a record-specific review.

Damaged or wrong item

Email support@gt40marine.com within 7 days of delivery with your order number and photos. We will reship the correct item or refund, and email a prepaid label for the wrong item if applicable.
