How much fuel does a 40 HP outboard used?
4 gallons per hour
A 40 hp motor would burn 4 gallons per hour.
How much fuel does a 4 stroke outboard use?
On average, an in-tune four-stroke gasoline engine will burn about 0.50 pounds of fuel per hour for each unit of horsepower. Likewise, a well-maintained diesel engine burns about 0.4 pounds of fuel per hour for each unit of horsepower it produces.
Which outboard is most fuel efficient?
What outboard brands are the most fuel efficient?
- Suzuki.
- Yamaha.
- Tohatsu.
- Honda.
- Mercury.
- Evenrude.
How much fuel does a 40 foot boat use?
However, if you have a twin engine 40 foot sportfisher, you will only go about 33 miles at 40 knots. If you wanted to travel 300 miles, you’d need 450 gallons of fuel! Diesel engines consume about 1 gallon per hour for every 18 hp used.
Why is my outboard using so much fuel?
The main reason why boats will always burn more gas than cars is they run on water. Aerodynamics, wind resistance, waves, and drag affect the fuel consumption of a boat. Basically, a boat needs to use more fuel to cover the same distance a car will cover.
What is more fuel efficient 2-stroke or 4 stroke?
Four-stroke engines are more efficient due to less demand for fuel. Fuel is consumed once every four strokes versus two. Four-stroke engines are better for the environment due to reduced emissions. A two-stroke engine releases burnt oil into the air in addition to the exhaust produced.
How much fuel does a boat use per hour?
How much gas do boats use? Many small, personal watercraft boats tend to use 3-8 gallons of gas per hour at cruising speeds, while faster boats like speed and motorboats can use 20-30 gallons an hour. Depending on the weight, size, and style of your boat, you will use within this very large range.
How can I reduce the fuel consumption of my boat?
Marine fuel saving tips: Save money and make your boat go further in eight easy steps
- Don’t be a drag.
- Trim.
- If you find yourself having to use excessive trim tab or leg trim, adjust the weight distribution within the vessel.
- Clean your hull.
- Keep your engine tuned.
- Reduce your speed.
- Clean the propeller.
How efficient is a 4-stroke engine?
The four-stroke diesel engine has been used in the majority of heavy-duty applications for many decades. It uses a heavy fuel containing more energy and requiring less refinement to produce. The most efficient Otto-cycle engines run near 30% thermal efficiency.
Are 4 stroke engines more efficient?
How much fuel does a 40ft boat use?
How do I calculate fuel consumption of my boat?
To determine an average fuel usage at gallons per hour (gph), divide horsepower by 10. Therefore, a boater with a four-stroke, 250-hp marine outboard engine running at full throttle, or about 6,100 rpm, is using 25 gph.
What is the most fuel efficient speed for a boat?
between 25-30mph
For most boats, an engine’s most efficient running speed falls between 25-30mph. Diesel engines find their sweet spot somewhere beyond 1800rpm. Gasoline outboards usually find it between 3000-4000rpm.
Which is more fuel efficient 2-stroke or 4-stroke?
Compared to four stroke engines, two strokes are lighter, more efficient, have the ability to use lower-grade fuel, and more cost-efficient. Therefore, the lighter engines results in a higher power-to-weight ratio (more power for less weight).
How many horsepower is a Mercury fourstroke?
Mercury FourStrokes have long led the pack with clean, quiet, fuel-efficient outboard power, and now the gap grows even wider. Whether you pilot a small fishing boat or a party on a big pontoon, there’s a Mercury FourStroke that fits the bill. The 40, 50 and 60hp models are available with either standard or BigFoot gearcases.
What kind of oil does a Mercury 4 stroke outboard use?

How much fuel does a Mercury outboard use per hour?
Re: Mercury outboard fuel consumption Put the pencil away, forget the formula, and put a decimal point one position to the left of the last number in the horsepower rating. 40 HP = 4.0 gallons per hour at wide open throttle.
Is the Mercury fourstroke 25w40 compatible with SmartCraft?
