Fuel efficiency of outboard motors for fish/ski boats? - outboard motor fuel economy
I have a boat 16 'bass this summer, and I am amazed at the amount of gas you. I use 4.5 gallons every time I go fishing for a few hours and my engine is a 1990 Mercury 115 (2 times).
I believe that a new boat and I wonder about the fuel consumption. I would say that smaller engines use less fuel and new engines (2000 or later) more fuel than older engines. However, I have my suspicion that the experts.
1) Improving the outboard engines to power is no less traveled 'tall?
2) What are the new engines more fuel consumption than older?
3) Is 2-stroke engines getter a better performance than the 4-stroke engines?
To evaluate other ideas you have?

Outboard Motor Fuel Economy Fuel Efficiency Of Outboard Motors For Fish/ski Boats?

For many years the standard for determining the fuel consumption by about 2 stroke outboard 1gal/hr was 10 hp. Basically, you burn a 200 hp 20gal/hr at full power.
ReplyDeleteWith the new engine the fuel consumption is now much lower. 2-stroke direct injection engines tend to burn less fuel as it aged in neutral. You can also save on fuel especially at high speeds, but keep one thing in mind. It takes fuel to produce horsepower! A new 200-horsepower engine accelerator burn an earlier version of the same size, but the difference is not so important at the upper end of the spectrum as RPM idle speed.
Four-stroke outboards generally burn cleaner than older adults, and two strokes. Once again, the savings are much more sensitive to high idle speed.
A very important factor for the effectiveness is the power to weight ratio. At low speed and heavy boat light boat burns fuel very similar amounts. The acceleration of the boat, however, raises the amount of thrust for a heavy boat "on the level" required a lot easier to BOats. Therefore, heavy boat will burn more gas.
Both types of motors 2 4 advantages and disadvantages of a stroke.
At very low speed (in my experience, most of the FDI two motors of the movement) is more efficient than their counterparts in the 4-stroke. Since the increase in RPM midrange DI two strokes starting mileage lose 4 shots. When you launch the boat, I think both lines mpgs possibly even close to the accelerator.
I think 4 times together very well with smaller boats and aluminum docks. In fact, it's a pair of the organization of a large boat to explain the "up", without more fuel to compensate for his weight gain and lack of torque.
2-strokes correspond ships faster + heavier than the thrust / weight is more advantageous.
If you are new ships, to verify some information from the manufacturer on the mileage on their competitors. They "fudge" their answers a bit, but you should appreciate in a position to trends.
90 Merc 115 has been VERY-fuel-efficient driving, so I think you will see an improvement by a new engine with advanced technology. But not too much! It needs fuel to power! Also, remember that a boat is easier with a large aircraft engines, then pull the back of the gas in the midrange and lower fuel consumption, while supporting the plan of a smaller engine, which held upright on the accelerator to the same speed to obtain.
What do you talk to your dealer ship on other options for fuel economy. A dummy can make a big difference, because it is possible to load and weight distribution.
I hope not to muddy water
Usually when we talk about fuel on a ship talking gallons per hour at certain rpm. You will find the new outboard motors, especially the four strokes are much better with fuel from the age of two strokes. Low-powered engines are not necessarily better fuel economy when the engine is too small for the boat will work harder to travel the same distance and therefore use more gas. Four-stroke engines, better fuel economy, but also weigh about 20% T0 30% more, so you may lose some performance. Some of the latest technologies (twice as EvanRude E-Tech) approach to the consumption of the four strikes of their weight and maintenance-game on the following four occasions. Also, do you not say, but I suspect, a 1990 115 can not have oil injection system, which means that the oil and gas premix. This can reduce fuel consumption, the mix is the worst possible conditions for an engine is running (high-speed or RPM) at a speed slower than the heavy oil mixture is done.
ReplyDeleteAnother factor is the performance of outboard iNSTALLATION engine too high and too low in May cavatate and increased friction, which reduces fuel consumption. A mechanic can inspect the outboard motor is properly mounted. And even if you do not want too small for the oversized boats more fuel costs, and most boats do not have time to go fast to get the fish. So if you're big tournaments silver fish, I recommend you follow the manufacturer's recommendations for a smaller boat for a boat that you get. Good luck!
Deal with it. It is as if one rubber ashphalt.
ReplyDeleteThe energy transfer is ineffective at best.
It's a hobby decadent about this game in the water.
