Our Marine Diesel Service Process
Initial Assessment
We review your concerns, engine history and the conditions under which the problem occurs.
Visual & Mechanical Inspection
We inspect critical engine components, fluids, belts, hoses, wiring and related systems.
Advanced Diagnostics
When appropriate, we use computer diagnostics, fault codes and professional testing equipment.
Root Cause Analysis
We determine what is actually causing the problem rather than simply treating the symptoms.
Repair Plan
We explain our findings and recommend the appropriate repair, testing or next step.
Professional Repair
Approved repairs are completed using the appropriate parts, procedures and service methods.
Testing & Sea Trial
We test engine operation and, when needed, verify performance under real operating load.
Final Verification
We confirm the original problem has been addressed and provide any additional recommendations.
