1. Dirt and Dust: Dirt and dust can enter the engine through the air intake system, leading to abrasion of engine components such as piston rings, cylinder walls, and valves. This can result in increased friction, reduced compression, and decreased engine efficiency.
2. Water: Water can cause serious damage to engines, particularly in diesel engines where water contamination can lead to injector and fuel pump damage. Water can also cause corrosion of metal components, leading to premature wear and failure.
3. Fuel Contaminants: Contaminants in fuel such as dirt, rust, and water can clog fuel filters, injectors, and fuel lines, leading to poor engine performance, rough idling, and decreased fuel efficiency. In severe cases, fuel contamination can cause engine stalling or failure to start.
4. Oil Contaminants: Contaminants in engine oil, such as dirt, metal particles, and sludge, can accelerate wear on engine components, reduce lubrication effectiveness, and cause overheating. This can lead to increased friction, premature component failure, and costly repairs.
5. Coolant Contaminants: Contaminants in engine coolant, such as dirt, rust, and air bubbles, can lead to corrosion of cooling system components, blockages in the radiator and hoses, and decreased heat transfer efficiency. This can result in engine overheating, coolant leaks, and potential engine damage.
6. Exhaust Contaminants: Exhaust contaminants such as carbon deposits, sulfur, and nitrogen oxides can accumulate in the exhaust system, leading to restricted airflow, increased back pressure, and reduced engine performance. Additionally, emissions of harmful pollutants can lead to environmental concerns and regulatory issues.
7. Combustion Chamber Contaminants: Contaminants in the combustion chamber, such as carbon deposits and oil residue, can interfere with the air-fuel mixture, combustion process, and exhaust gas flow. This can result in reduced power output, increased fuel consumption, and elevated emissions levels.

To mitigate the impact of contaminants on engine performance, regular maintenance is essential. This includes changing air, fuel, and oil filters at recommended intervals, using high-quality fuel and lubricants, flushing and replacing coolant as needed, and performing periodic inspections and cleaning of engine components. Additionally, proper storage and handling of fuel, oil, and coolant can help prevent contamination before it reaches the engine.

Where did I get the water? Check the fill port gasket and vents to see if that is how the water entered the tanks.

Water may have been delivered to you but it is hard to prove without going back to the source and inspecting their supply.

Drain the separator and keep a sample of the fuel. Letting the boat sit for a day or two and restart the engine. Compare what you see in the separator now with the sample you kept. If the problem came from water on the tank bottom, after sitting for two days in calm waters the fuel should clear up.

After assuming water is on the bottom of the tanks we must get it out. Steel Camel,  https://www.steelcamel.com/, has a water absorbing sock that will work if you can get it into the tank. Or we must find a way to get a pickup tube to the bottom and suck out the water. No telling of there is 1 gallon of 20 gallons of water on the bottom.

To clean what you have is to install a Dieselcraft Fuel Purifier followed by the Racor and recirculate for as long as it take, 8 hours, and the fuel should clear up.

DO NOT add any additive. Some additive promote “allows the water to be burned off.” Water burns? Engine manufacturers allow ZERO water in the fuel, burnable or not. ZERO water. The only way to remove the water is a mechanical purifier/separator, absorbing media or a vacuum cleaner but not burning.

Diesel fuel starts to degrade and become contaminated within 28 days of storage. Typically, fuel can be stored 6–12 months, but without proper care, its quality will decline.

To maximize storage life, many companies recommend:

• Keep fuel cool, ideally around 70°F
• Treat with biocides and stabilizers
• Maintain tanks per NFPA 110 standards

According to NFPA 110, diesel “Storage Life” is 1.5 to 2 years. Tanks should be sized so fuel is consumed within that period, or stale fuel must be replaced.

The Most Critical Step: Keep Water Out

Water is the number one killer of stored diesel fuel. It encourages microbial growth, leading to bacteria, sludge, and engine damage.

• No water = no bacteria
• No bacteria = no need for biocides

Regular fuel polishing is the most effective way to remove water, sediment, and microbes—but it can be expensive.

Deciding on Fuel Management

Consider your fuel volume:

• 200 gallons vs 5,000 gallons – costs and methods vary.
• Decide if contracting a fuel polishing service or investing in a machine makes the most sense for your operation.

Meanwhile, for small tanks, simple devices can quickly remove water and prevent early contamination.
