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
