Buying from Marine Diagnostic Tools

Marine Diagnostic Tools is built for independent marine techs, boatyards, and fleet shops that want dealer-level diagnostics across many engine brands without buying each OEM tool. A boat owner with one engine brand may be better served by a single-brand MINI Scan Tool, or by a dealer visit. Before buying a full kit, call sales to confirm the total price, which cables you'll need, and the training required to qualify for the money-back guarantee.

Shipping
Most orders process the same day or within 3 business days, with orders placed after 11 a.m. processed the next business day. Shipping charges are calculated at checkout, and tracking is emailed when the order ships.
Returns
Master and Gas Pro kits can be refunded within 30 days of delivery after tech support troubleshooting and training enrollment. MINI kits can be returned within 30 days minus a 20% restocking fee; software, renewals, used kits, and customer-caused damage are not refundable.
