What RPM should a boat run at?
The full-throttle limit for modern marine gasoline motors ranges from 4800 to 6000 rpm. (By comparison, your car’s engine probably turns less than 2500 rpm at freeway speeds.) Most mechanics and engineers suggest the best cruising speeds are achieved at 3400 and 3800 rpm respectively.
Should you run a boat at full throttle?
As long as you are propped correctly and can hit the upper end of the RPM range, [to run an engine at its maximum throttle all the time] is not a problem. Most smaller engines have two speeds, OFF and WOT. Very rarely does an engine wear out. Keep up with maintenance and you will be fine.
How do you calculate fuel consumption from horsepower?
Simple MethodFormula To Estimate Maximum Engine Fuel Consumption. Gallon Per Hour (GPH) = (specific fuel consumption x HP)/Fuel Specific Weight. … 300-hp Diesel Engine Example. GPH = (0.4 x 300)/ 7.2 = 105/7.2 = 16.6 GPH.300-hp Gasoline Engine Example. GPH = (0.50 x 300)/ 6.1 = 150/6.1 = 24.5 GPH.Other Related Resources:
How much fuel does a 150 hp outboard used?
For example, a 150-horse engine will use about 15 gallons per hour. Though these figures represent averages and can vary from 10 to 20 percent, they’ll put you in the ballpark so you can plan a long-distance cruise without fear of running out of gas.
How much fuel does a 15 hp outboard use?
By this metric you should be burning only 15/10 = 1.5 gallons per hour.
How much does a 150 hp outboard cost?

Which is better 2 stroke or 4 stroke outboard motor?
Fuel economy and speed are comparable between two-strokes and four-strokes. Two-strokes tend to weigh less but can accelerate faster. Four-strokes tend to be quieter and have more torque than two-stroke outboards.
How much fuel does a 40 hp outboard used?
A 40 hp motor would burn 4 gallons per hour.
Is it bad to run an outboard engine at full throttle?
As long as an outboard is propped correctly, running at full throttle is fine.
Will raising outboard increase RPM?
Raising the motor one hole will most likely increase the rpm’s by a couple hundred, you should gain in top speed as well.
Why are boats so fuel inefficient?
Your boat is inefficient because you are trying to exceed “hull speed” and the power needed to get the boat up on step and keep it there is enormous.
How much is a gallon of marine fuel?
Using $3.25 per gallon for marine gas, that comes out to $325 for each excursion. That translates into $1,300 a month. Perhaps your boating season is four months. That brings your annual fuel cost to $5,200.

How much fuel does an outboard motor use?
At full throttle and averaged across makes and models, those engines burn about one gallon of fuel per hour for every 10 horsepower (hp). Generally, it takes about 2.5 hp to plane 100 pounds for a near flat-bottomed boat. Other shapes, such as deep-v hulls, require more power.

What is the formula to calculate fuel consumption?
The following formula is used to calculate fuel consumption in litres / 100kms, the most commonly used measure of fuel consumption. (Litres used X 100) ÷ km travelled = Litres per 100km.

How far below the bottom of the boat should the prop be?
If you have a short shaft motor, the top most part of the transom and the lower most part of the boat should be about 15 to 16 inches. For a long shaft, I think 20 to 21 inches is correct.
Are boats more fuel efficient than cars?
Why Do Boats Burn More Gas Than Cars? Boats are one of the least fuel-efficient vessels on the planet. Boats will measure their fuel consumption in gallons per hour (GPH), while cars use miles per gallon (MPH). … Because of this, you are less likely going to save on fuel-efficiency with a boat than you are with a car.
