How do you calculate the fuel consumption?
Divide mileage by fuel usage to see your car’s fuel consumption. This tells you how many miles you drove per gallon of gas. For example, if you drove 335 miles before refueling, and you filled your car up with 12 gallons of gas, your fuel consumption was 27.9 miles per gallon, or mpg (335 miles / 12 gallon = 27.9 mpg).
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.
What boat has the best gas mileage?
Trawler Boats Many trawlers operate on diesel engines, which tend to be among the most fuel efficient boat motors. In addition, trawlers are constructed with slow-speed, semi-displacement hulls that help contribute to better boat gas mileage.
What RPM should you run your boat at?
Most mechanics and engineers suggest the best cruising speeds are achieved at 3400 and 3800 rpm respectively.
How much fuel does a 50 hp outboard use?
Yamaha Outboard Fuel Consumption Chart
| Fuel Consumption Chart LPH | Idle | WOT |
|---|---|---|
| Yamaha 25 hp 4-stroke Outboard | 0.38 | 9.45 LPH |
| Yamaha 50 hp 4-stroke Outboard | 0.75 | 18.5 LPH |
| Yamaha 90 hp 4-stroke Outboard | 1.33 | 34.4 LPH |
| Yamaha 115 hp 4-stroke Outboard | 1.50 | 36.6 LPH |
How fast can a 50 hp boat go?
Depending on the type of boat and its weight, 50 hp can power you along at between 15 and 47 miles per hour.
How can I improve the gas mileage on 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.
What is the most fuel-efficient hull design?
planing hull
What’s the most fuel efficient boat hull design? The answer to that question is a planing hull. Planing hull boats are designed to glide smoothly on top of the water when enough power is applied. Both flat-bottom and vee-bottom hull shapes are considered to be planing boat hulls.
How much fuel does a diesel boat engine burn?
Likewise, a well-maintained diesel engine burns about 0.4 pounds of fuel per hour for each unit of horsepower it produces. These figures don’t take drag of the boat, sea conditions, or efficiency losses through transmissions and bearings into account.
How much fuel does a 4-stroke engine burn?
This makes it important to know that gasoline weighs about 6.1 pounds per gallon and diesel fuel 7.2 pounds per gallon. On average, an in-tune four-stroke gasoline engine will burn about 0.50 pounds of fuel per hour for each unit of horsepower.
How do you calculate the fuel consumption of a boat?
Calculating Fuel Consumption. To apply these formulas to your boat, just plug in its horsepower rating and multiply it by the specific fuel consumption average, then divide the product by the fuel specific weight. Another way is to take the total engine horsepower and divide it by 10 for gas engines or .06 for diesel engines.
How much fuel does it take to drive 75 miles?
At 15 knots the 75-mile trip will take 5 hours and will consume 117 gallons, while at 25 knots the time falls to only 3 hours and 132 gallons. The fuel cost for an extra 10 knots is only $60.
