Our Diagnostic & Repair Process
1) Discovery & Scheduling
We start with your symptoms, maintenance history, and operating profile, then schedule a visit that fits your window. If your vessel is inoperable in another area, we coordinate mobile support to you whenever possible.
2) On-Board Inspection & Testing
We perform a systematic inspection—fluids, filters, belts, cooling, electrical, and rigging—then run tests and log data to pinpoint the failure mode. Our goal is to prevent repeat faults and catch hidden contributors like restrictions, air leaks, or alignment issues.
3) Estimate, Parts & Approval
You get a clear estimate and timeline. We’ll never make false promises—just honest communication about parts lead times and what’s critical to get you safely back on the water.
4) Repair, Sea Trial & Follow-Up
After repairs, we verify performance at the dock and under load. You receive notes on findings, recommendations for future maintenance, and a reminder schedule aligned to your engine hours and usage.

Do you really come to my boat?
Yes. As a mobile marine mechanic, we work dockside or at your storage location to minimize downtime and logistics hassles.
Which engines do you support?
Most major diesel brands including Cummins, Volvo Penta, Yanmar, Caterpillar, Beta, Perkins, MTU, and others. We do not service gasoline engines.
Can you help before I buy a boat?
Absolutely. We perform pre-purchase engine surveys, compression checks, oil analysis, and sea trials so you know exactly what you’re buying.

Follow your manufacturer’s hour/annual intervals. Many owners schedule seasonal services around spring commissioning and fall lay-up to stay ahead of issues.
