What to know for Diesel Troubleshooting
Use symptoms to choose the next safe check instead of guessing randomly.
No start, starts then stops, overheating, smoke colours, vibration, alarms, and decision trees. This module is mapped to the published course boundary for Marine Diesel Engine Revision and written as an independent revision aid, not official training material.
Key Points
- No-start checks differ from stops-after-starting
- White, black, and blue smoke suggest different areas
- Vibration may be propeller, mount, alignment, or fuel related
- Stop if continuing could cause damage
