Maybe not a problem on still water like an inland canal but on the sea or river it can be disastrous. Water in diesel fuel is a serious problem that should be addressed immediately. As a potentially catastrophic contaminant excessive levels of water in fuel can reduce engine performance because of the reduction of energy available within the fuel. The fuel pump in a diesel engine operates at a very high pressure and with very precise tolerances.

Due to the issues we talked about earlier about what will happen when the water enters the combustion. Visually inspect for fuel cloudiness as this would indicate the presence of water. Not only this but you ll get either black or white smoke during engine operation. Other sources might be harder to detect like a tank vent improperly placed by the boatbuilder.

Slime or sludge brown or black in colour in the filter. Slimy clogged filters hazy cloudy fuel a build up of sludge in the fuel tank excessive smoke a loss of rpm and power foul odour corroded injectors. Look for rough starting and erratic idling. Newer diesel engines have more water problems than older ones.

Any contaminant including water can cause costly damage. Rough idle is. Just like the symptoms of the common cold include congestion fever sore throat and headaches your engine experiences symptoms when it has water injected into it. Because the water is.
