CAUSE
● Boat abnormally loaded
● Fouling on underwater hull
● Faulty/damaged propeller
● Insufficient fuel flow
– fuel filters clogged (due to contaminants/paraffin
precipitation in the fuel as a result of low outside
temp.)
● Water in fuel
● Insufficient air flow to engine
– air cleaner filter clogged
– air leak between turbo and engine’s inlet manifold
– faulty turbocharger
– poor engine compartment ventilation
● Throttle controls incorrectly adjusted
● Charge air cooler (CAC) clogged
● Excessive pressure in the exhaust system
● Injector malfunction
● Incorrect adjustment of Injection pump
● Smoke limiter malfunction
– smoke limiter seizing
– pressure pipe between inlet manifold and smoke
