Filters & Water Separators

(80 products)

Clean fuel is crucial for the performance and longevity of your boat engine. In the awn online shop, you'll find suitable filters and water separators that reliably remove moisture and dirt particles from your fuel system – for trouble-free operation on the water.


  • Why water separators are important in boats

    When operating a boat engine, condensation can enter the fuel tank—especially during extended layovers or when temperatures fluctuate. Water in the fuel can lead to corrosion on injectors, lines, or other components and negatively impact combustion in the engine. Water separators effectively prevent this.

  • Combination of fuel filter and water separator

    Many systems combine a water separator with a fine filter. This not only filters water, but also deposits, rust, or other contaminants from the fuel. Ideal for gasoline and diesel engines—or both fuel types, depending on the model.

  • Selection according to throughput and engine type

    When selecting a filter, pay attention to the maximum fuel flow per hour—especially for powerful outboard or inboard engines. Depending on the model, there are different filter inserts and thread sizes that should fit your system exactly.

  • Change intervals and maintenance

    The replacement interval depends on usage, fuel quality, and filter design. Early signs of a worn filter include starting problems, rough idling, or reduced acceleration. Record operating hours and check the condition of the filter element regularly—especially on longer journeys.

  • More safety with the right accessories

    Whether for long-distance trips or occasional excursions, high-quality filter and separator units ensure a consistent fuel supply. In the awn Shop, you can also find suitable replacement cartridges, seals, and filter housings – for reliable engine performance on every trip.
