Water in Boat Engine Oil: What to Do

What Causes Water in Engine Oil?

There are several reasons why water might end up in your boat’s engine oil:

1. Failed Exhaust Riser: If the exhaust riser on your vessel is faulty or improperly installed, water can enter the system through the exhaust pipe and contaminate the engine oil.
2. Raw Water Ingress: When a boat is docked at a marina or in rough seas, raw seawater can sometimes find its way into the cooling system, mixing with the engine oil.
3. Marine Fuel Contamination: If you accidentally use contaminated marine fuel (like petrol instead of diesel) or if your fuel has been exposed to salt water, it can cause phase separation and introduce water into the engine.
4. Submerged Engines: During a storm or when docking in shallow waters, an engine might be submerged for a short period, leading to contamination.

What Should You Do?

If you suspect that your boat’s engine oil is contaminated with water, here are some steps you should take immediately:

• Do Not Start the Engine: This is crucial. Starting the engine under these conditions can cause severe damage and make the situation worse.
• Contact EEK Mechanical: We offer 24/7 emergency services for marine fuel and oil contamination recovery. Our certified technicians will arrive at your location to safely drain, flush, and polish the contaminated system.
• Prevent Further Damage: Keep the engine off until professional help arrives. Do not attempt any DIY fixes or modifications.

Why Not Start the Engine?

Starting the engine under these conditions is a serious mistake. It can cause:

• Damage to Components: Water in the oil can lead to corrosion and wear on critical components, such as pistons, cylinders, and bearings.
• Increased Fuel Consumption: Contaminated fuel can result in higher fuel consumption and reduced performance.
• Potential for Further Damage: If you start the engine, it could cause further contamination or damage that would be harder to repair.
