Generator + Thruster Service
Generator or thruster problems can involve mechanical, electrical and control systems at the same time. Keelmark troubleshoots the complete system instead of guessing at individual components.
Systems that need real diagnostics.
Generator troubleshooting
We diagnose no-start, hot no-start, shutdown, fuel-supply, cooling and electrical complaints on onboard marine generators.
Bow + stern thrusters
Weak thrust, intermittent operation, thermal shutdowns, contactor faults and low-voltage supply problems can all look similar from the helm. We test the system where the failure occurs.
Battery supply + controls
High-current equipment depends on healthy batteries, cables, connections and controls. Voltage testing under actual load is often the difference between finding the fault and replacing good parts.
