| | Possible Cause | Remedy | | :--- | :--- | :--- | | Engine cranks but will not start | 1. No fuel (tank empty, shutoff valve closed, air in system). 2. Glow plugs defective. 3. Clogged fuel filter. | 1. Check fuel level and valve position; bleed the system. 2. Test and replace glow plugs. 3. Replace the fuel filter. | | Engine starts but runs rough | 1. Air in the fuel system. 2. Dirty or faulty injector. 3. Low compression (worn piston rings or valves). | 1. Bleed the fuel system. 2. Clean or replace the injector. 3. Perform a compression test; overhaul engine if needed. | | Engine stalls at idle | 1. Idle speed set too low. 2. Clogged fuel filter. 3. Air in fuel system. | 1. Adjust idle speed screw (to 750-800 RPM). 2. Replace fuel filter. 3. Bleed the system. | | Engine knocks or makes unusual noise | 1. Water in fuel (causing injector knock). 2. Worn main or connecting rod bearings. 3. Loose flywheel bolts. | 1. Drain water from fuel/water separator. 2. Inspect and replace bearings. 3. Torque flywheel bolts to specification. | | Engine overheats | 1. Low coolant level. 2. Faulty thermostat. 3. Broken seawater pump impeller. | 1. Add coolant and check for leaks. 2. Replace thermostat. 3. Replace impeller and clear blockage. | | Excessive exhaust smoke | 1. White smoke: Air in fuel, faulty glow plugs, low compression. 2. Black smoke: Overloaded, clogged air filter, faulty injector. 3. Blue smoke: Worn piston rings, valve guides. | 1. Bleed fuel system; replace glow plugs; check compression. 2. Reduce load; clean/replace air filter; service injector. 3. Overhaul engine. |
Replace fuel filter elements (e.g., C0506-1000) every 100-200 hours or annually. Ensure the 161L aluminum fuel tank is filled
: Typically caused by air trapped in the high-pressure fuel lines, a clogged fuel filter, or cold cylinders failing to hit combustion temperature.
