Engine Efficiency


An efficient engine is not only good for the environment, it will give you a better ride on the water and a less painful experience filling up at the pump!
Follow our best practice to keep both your emissions and your costs down, and to maximise the efficiency of your engine.


  • Regularly check and service your engine. Fresh oil, clean spark plugs and dust free air-filters all help to lower fuel costs and emissions.
  • Use CE marked outboard engines manufactured after 2005 or electric engines to increase fuel efficiency, reduce noise and decrease emissions.
  • Fitting sound insulation around the engine can cut noise by 85%.
  • Vibration absorbers can also reduce structural noise by 85%.
  • Consider an electric powered craft. They have low emissions and are very quiet.
  • Try switching to biodegradable hydraulic and lubricating oils.
  • If you have an on-board fire for heating, only use smokeless fuels, especially in urban areas.
  • Get Planing – Whilst up on the plane the drag of the hull is reduced allowing a more efficient drive.
  • Be on an even keel – the hull needs to be as level as possible. If it is not, power and fuel will be lost trying to push the hull up rather than along. Ensure weight is distributed evenly on the craft to keep it level and provide a smoother ride and more mileage per litre.
  • Regularly clean your boat to remove biofouling to reduce drag and fuel consumption. This will also help remove harmful invasive animal and plant matter.
