The problems ethanol fuel causes boaters are well documented. It attracts and absorbs water, loosens debris in fuel systems, and can lead to costly breakdowns or even leave you stranded on the water. Follow these 4 boat fueling tips to protect your engine and ensure trouble free boating all season.

  1. Buy fuel with no ethanol whenever possible. If you must buy ethanol fuel, buy from a busy gas station.
  2. Allways add marine formula fuel stabilizer when you fuel with ethanol gas. Read the bottle for the correct amount of stabilizer to add per gallon of gas.
  3. Add a 10-micron fuel filter/water separator on each engine. Allways carry a spare filter when out boating.
  4. Use a fuel conditioner to help clean gum and varnish from fuel injectors, carburetors, intake valves, ports, and combustion chambers.
