A good rule of thumb for the amount of fuel needed for a trip is to ration one-third for the outward journey, one-third for the return journey, and one-third as a reserve.

How to calculate fuel consumption for a Boat?

To find average fuel consumption in gallons per hour (gph), divide the horsepower by 10. Therefore, a boater with a 250 hp four-stroke engine A marine outboard motor running at full throttle or about 6,100 RPM running, consumes 25 gph. But an engine is most efficient at 75 to 80% of rated power and not at full throttle.

And under what conditions is a portable fuel tank filled?

All portable fuel tanks must do this from the boat be filled from. Once onboard, store portable fuel tanks in a well-ventilated area away from the engine and electrical equipment.

Similarly, how much fuel does an outboard motor use?

On average, a tuned four-stroke gasoline engine burns about 0.50 pounds of fuel per hour for each horsepower unit. Likewise, a well-maintained diesel engine burns about 0.4 pounds of fuel per hour for each unit of horsepower produced.

What should be done before starting an inboard engine?

What to do What You should do before you start your gasoline inboard

1. Let the engine be primed. To start, you should completely remove the engine cover.
2. Change the fuel filter/water separator.
3. Change the engine oil.
4. Change the oil filter.
5. Charge the battery.
7. Check the cooling system.
8. You’re good to go!

## What is good fuel economy?

Anything listed as less than 6 liters/100 km or more than 16.5 km/1 liter , is considered to be quite good. The first (and most common) reference is liters per 100km (liters/100km). That’s how many liters of petrol the car needs for 100 km. You’ll often see it referred to as “fuel economy”.

## How fast can a 25hp boat engine go?

25 mph sounds about right, which is a decent clip.

## How to calculate fuel burn rate?

Simple method

1. Formula to estimate maximum engine fuel consumption. Gallons per hour (GPH) = (specific fuel consumption x hp)/specific fuel weight.
2. Example of a 300 hp diesel engine. GPH = (0.4 x 300)/ 7.2 = 105/7.2 = 16.6 GPH.
3. Example of a 300 hp petrol engine. GPH = (0.50 x 300)/ 6.1 = 150/6.1 = 24.5 GPH.

## How can I make my boat more fuel efficient?

Here are some ways you can improve your fuel economy.

1. Slower. Some of the best running outboards will burn in excess of 3mpg at peak efficiency.
2. The sweet spot.
3. Use a fuel monitor.
4. Minimize mileage.
5. Choose the right motor size.
6. Use the right propeller.

## How much fuel does a mega yacht use?

The standard fuel consumption for a 71 meter yacht is 500 liters per hour, which means that an average of \$400,000 (£265m) per vessel is spent on fuel each year.

What is the most fuel efficient boat?

Trawler boats. Many trawlers are powered by diesel engines, which are among the most fuel efficient boat engines. In addition, trawlers are designed with semi-displacement hulls for slow speeds, which contribute to the boat’s better fuel economy performance.

## How far can a yacht go on one tank of fuel?

On average, a 75 -foot motor yacht with a tank capable of holding 11,000 liters of fuel but able to travel up to 1500 nautical miles. When comparing your yacht to this average, be sure to compare your tank size as well. Example: A 95 foot yacht with a 9000 liter fuel tank can travel up to 1,200 nautical miles.

## How much fuel does a 100hp outboard motor use?

Example: A A 100hp engine uses about 10 US gallons or 40 liters per hour at maximum RPM.

## How much horsepower does my boat need?

The rule of thumb is based on weight alone, and says you should have between 40 and 25 pounds of weight for each horsepower. For example, a 5,000 pound boat might have a 125 to 200 horsepower engine.

## How far can a boat go on one tank of fuel?

Speaking of an average sailing yacht between 35-45ft length, calm seas, no engine overspeed, etc. I would calculate 1 liter/hour at a cruising speed of about 4 knots. With a (typical) 100 liter fuel tank this would give around 400 miles.

## What is the average MPG for a boat?

Normal cruising in average conditions at 30mph we get around 3 mpg.

## Do boats use the same gas as cars?

Do boats and/or large ships use the same fuel like land vehicles, like gas or diesel? – Quote. Stephen Carey, marine engineer for over 50 years. Short answer – merchant vessels use IFO180 or IFO380 heavy fuel oil in both the 2-stroke main engines and 4-stroke generators.

## How much fuel does a 60hp outboard motor use?

When you “open” an outboard to its full throttle (WOT) range, it burns an average of 1 gallon per hour per 10 horses, whether it’s a 2-stroke, 2-stroke direct injection or 4-stroke (so your 60 would burn 6 gallons an hour).
