Machine diagnosis, compression tests, leak detection, and expert services.

The true condition of an engine is revealed not only by experience but also by accurate measurement and testing equipment. At Fibromarin, every fault diagnosis is supported by electronic diagnosis, compression tests, and detailed system analysis. A service approach based on data, not guesswork.
All fault codes are read and analyzed by connecting to the ECU system of modern marine engines. Past faults, active errors, and pending warnings are reported comprehensively.
The compression pressure of each cylinder is measured separately. The pressure difference between cylinders provides critical information about the piston, rings, and valve condition. It is the most reliable method for detecting early wear.
While the engine is running, RPM, power output, oil pressure, and exhaust temperatures are monitored in real-time. The system behavior is analyzed comparatively under cold and hot operating conditions.
Fuel pressure, injector spray quality, and fuel consumption measurements are conducted. The source of excessive consumption and power loss problems is precisely identified.
The effectiveness of the cooling system is checked with thermal cameras and temperature measurement probes. Hot spot detection, thermostat opening temperature, and coolant flow are analyzed.
The results of all tests are reported in writing. Identified issues, proposed solutions, and intervention priority order are presented to the boat owner.
Incorrect diagnosis leads to both time and money loss. At Fibromarin, every diagnosis process is conducted with a systematic and documented protocol. We do not recommend any part replacement without accurately identifying the problem.
A written report and cost estimate are provided as a result of the diagnosis
No unnecessary part replacements are made; every decision is data-driven
Standard test protocols applied by MAN certified technicians
