One major problem for boat owners when bringing their vessels back into service after a winter lay-off is problems with the engine running 'rough' or refusing to fire altogether. Problems like these are often due to 'diesel bug' in the boat's fuel tank. So, what is diesel bug, and how can you stop it infecting your boat's fuel tanks? Read on for some helpful tips.
How 'diesel bug' gets into fuel tanks
Diesel bug is caused by water in your boat's fuel tank. When water gets into a fuel tank, it creates the perfect environment for bacterial growth, colloquially known among boaters as diesel bug. Diesel bug can be extremely difficult and costly to eradicate once it's entered the boat's system.
Diesel bug can lurk undetected in your fuel tanks until the fuel is stirred-up by rough seas or the natural life cycle of the diesel bug fungus reaches a stage when dieback occurs and the dead matter is released into the fuel. The dead bacteria and fungus releases black slime, which causes blocked filters and engine problems.
Water in your fuel tank
Water contamination of your fuel tanks occurs for a number of reasons including:
In addition to the above, water can get into your fuel tanks through damaged or leaky seals around the engine casing. As part of your winter maintenance routine, always check for signs of water ingress around the engine and vents.
How to prevent diesel bug
Ideally, you should drain your boat's fuel tanks regularly to make sure that they are free-from pockets of water. If this isn't possible, there are a few other ways of stopping water from entering your fuel tanks.
Don't let diesel bug ruin your boating fun this season; follow the tips above to help keep water out of your boat's fuel tanks, ensuring that the bugs won't bite! Contact marine services for more information.Share
