Protect Your Yacht from Diesel's Worst Enemy, Water!

Do you have a problem with water in your fuel?

Yacht engines are not designed to handle water content, despite being in the water most of the time! When water enters the fuel tank it contaminates the fuel, allowing diesel bug sludge to form. This sludge can block filters, pumps and injectors, and the contaminated fuel can then cause loss of engine power, the yacht not being able to get up to speed and fuel system corrosion, which can all be costly to fix and repair, causing downtime for the vessel.

Do you have a problem with water in your yacht fuel tank?

All yachts and vessels boats can fall victim to water getting in the fuel tank through condensation, which settles at the bottom of the tank as a layer of “free water”, that then forms diesel bug sludge. Modern diesel also attracts water due to its increasing bio-content, but if you cant see inside your fuel tank, how can you prevent this from happening?


Using FUELSTAT you can test the diesel for microbial content (diesel bug) using only a few drops of fuel, with a clear result in minutes. You can then use an Aquafighter water absorber, placed into the opening of the fuel tank, to quickly absorb any water molecules that create diesel bug, leaving the diesel clear and water free, ready to use. We offer a FUELSTAT and Aquafighter Lite bundle so you can sort contaminated fuel in your yacht's fuel tank quickly and safely, before you next set sail.

Aquafighter Lite - The complete solution to water in fuel

Aquafighter is the only way to remove both free and suspended water from your fuel.

The Aquafighter Lite does this by:

  • Being added into the fuel tank when the yacht is docked.
  • It then absorbs the free and suspended water molecules to keep fuel water-free.
  • It prevents diesel bug sludge forming and the costly damage to the boat engine it causes.
  • The absorber is easily removable for replacement when it has reached absorption capacity.
  • The Aquafighter Lite eliminates the need for fuel additives.

FUELSTAT - Fast & Efficient Fuel Testing

FUELSTAT is designed for testing diesel for microbial contamination and checking the water content that causes the diesel bug sludge to grow in yachts and small fuel storage tanks.

  • Only finds micro-organisms that do damage to fuel.
  • The test take as little as 15 minutes
  • .Easy-to-understand alert levels.
  • The process is self-contained, requiring no additional equipment.
  • An individual can carry out the tests with only minimal training.

FUELSTAT and Aquafighter Lite bundle

Whether you’ve already experienced water in your fuel tank symptoms, or want to prevent the inevitable whilst your yacht is stored away for winter, the FUELSTAT & Aquafighter Lite bundle can help you in removing water from your fuel tank!
