## Are 4 strokes more fuel efficient?

4-Stroke Outboards Pros From a cost perspective, a 4-stroke outboard is far more fuel efficient than a 2-stroke. The fuel efficiency of a 4-stroke motor can be 50% better than that of a 2-stroke motor with the same HP.

## How much gas does a 4 stroke outboard use?

An in-tune four-stroke gasoline engine will burn about 0.4 to 0.45 pounds of fuel per hour for each unit of horsepower. A well-maintained two-stroke outboard burns nearly 0.6 to 0.8 pounds of fuel per hour for each unit of horsepower.

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. Some simple math can estimate the number of gallons consumed per hour.

What’s better 2-stroke or 4 stroke?

Because 2-stroke engines are designed to run at a higher RPM, they also tend to wear out faster; a 4-stroke engine is generally more durable. That being said, 2-stroke engines are more powerful. Two-stroke engines require pre-mixing of oil and fuel, while the 4-strokes do not.

### Do you mix oil and gas in a 4-stroke engine?

Four-cycle engines do not require mixing of oil & gasoline and have separate gasoline and oil tanks. Only four-cycle engines have a separate engine oil reservoir on the back or side, with another cap (usually yellow) for checking & filling the oil reservoir.

### How do you calculate fuel consumption on a 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. But, an engine is most efficient at 75 to 80 percent of rated output rather than at full throttle.

How much gas does a Tritoon use?

Slower pontoon boats will not use as much fuel as quick motorboats. Your potential gas consumption could be as low as 5 gallons an hour with a smaller horsepower engine. If you use your boat for five hours weekly, that could equate to around \$3,000 dollars a year on fuel with current 2018 prices.

How much fuel does a 70 foot yacht use?

As a working figure, the average 70-meter yacht will use around 500 liters of fuel an hour and this is just to keep the engines running without actually moving the boat. If such a vessel were to achieve cruising speeds of around 18 knots, the fuel cost per hour would be roughly around \$2500.

## Why are boats so fuel inefficient?

Why do boats burn so much gas? 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 are the advantages of a 4 stroke engine?

More fuel efficiency :- 4 stroke engines have greater fuel efficiency than 2 stroke ones because fuel is consumed once every 4 strokes. Less pollution :- As power is generated once every 4 strokes & also as no oil or lubricant is added to the fuel; 4 stroke engine produces less pollution.

Are Mercury outboards made in China?

Boating engine company Mercury Marine has been granted exclusions from 25 percent tariffs for its outboard engines manufactured in China. As a result, Chinese-made Mercury engines from 40 to 60 horsepower are no longer subject to a 25 percent import tax the U.S. placed on more than 1,000 made-in-China products.

Which is more fuel efficient 2 stroke or 4 stroke?

Some companies claim to be more fuel efficient than others, but in many cases, it’s a matter of splitting hairs. As long as it is a modern-day 2 stroke, it is most likely comparable to 4 strokes when it comes to fuel efficiency.

### How much fuel does a Honda outboard use?

Select Honda Outboard Test Model Stroke Displacement Fuel consumption WOT Honda BF 135 HP 4 stroke 2.4 L – 144 cid 12.9 GPH Honda BF 150 HP 4 stroke 2.4 L – 144 cid 13.4 GPH Honda BF 225 HP 4 stroke 3.5 L – 212 cid 19.5 GPH Honda BF 250 HP 4 stroke 3.6 L – 219 cid 22.8 GPH

### What’s the difference between 2 stroke and 4 stroke outboard motors?

If you’re a boat enthusiast, you’ve probably wondered what the differences between 2 stroke and 4 stroke outboard motors are. At first glance, many people assume that 4 stroke motors are more powerful and 2 stroke motors are designed for those looking for speed. However, this isn’t always the case.

When do you need an oil change on a 4 stroke motor?

In 4 stroke motors, there is an oil filter and self-contained oil cavity within the engine, similar to the way it works in a car. An oil change is typically required after 100 hours or one year of use. One of the biggest things to look for when choosing an outboard motor is reliability.
