One of the easiest ways to tell the difference between the two motors is to just listen to them. Many people who run in lakes and rivers prefer 4 stroke boat motors because they make great trolling motors and meet the 2006 EPA mandated requirements.
2 stroke vs 4 stroke.
Difference between 2stroke and 4stroke boat motors. In comparison to 4 strokes 2 stroke motors were lighter had quicker acceleration and were smaller and more portable. For these reasons 2 strokes dominated the market for many years. Despite this a common concern with 2 stroke motors was the fact that they would use more fuel to operate.
A 2-stroke engine doesnt use valves to regulate the fuelair intake or exhaust gas exit so it has fewer moving parts and is smaller and lighter. The 4-stroke engine is mechanically more complex relying on four piston strokes to complete its power cycle which gives it lots of torque. It really comes down to how the cylinders are lubricated.
4-stroke outboards have internal oil reservoirs and sumps which need regular oil level checks filter replacements and oil changes at least annually. 2-stroke outboards generally have an external oil tank with the oil and fuel mixture injected into the cylinder. These engines are also getting more powerful.
Today the average is 58 horsepower. While in 2010 the average engine power was 46 horsepower. Another development is the increase in the debate of 2 stroke vs 4 stroke.
Most people shopping for a new motor assume that a 4 stroke is more powerful and therefore better. But again modern technologies have closed the gap significantly. However 2-stroke motors will always be less fuel efficient by design.
A typical 4-stroke motor needs one or two oil changes per boating season. By contrast the oil in a 2-stroke motor must be changed all the time which can become more expensive to maintain. The construction of a two stroke engine is less-complex than a four-stroke engine making it a cheaper option.
Also due to being less complicated in construction than a four-stroke outboard the two-stroke outboard is comparatively lighter. 5 Reasons Why 2-Stroke Is Prefered Over 4-Stroke On Ships There are many circumstances where using a 2 stroke engine proved to be more advantageous than using a 4 stroke counterpart. Although a four stroke engine offers some clear advantages such as more speed less space better fuel efficiency and less pollution by design.
There are some vital advantages of using a 2 stroke counterpart. Typically a 2-stroke engine creates more torque at a higher RPM while a 4-stroke engine creates a higher torque at a lower RPM. The 4-stroke engine is also much quieter a 2-stoke engine is significantly louder and has a distinctive high-pitched buzzing sound.
One of the easiest ways to tell the difference between the two motors is to just listen to them. 2-stroke motors usually sound louder and have a higher pitch sound than the 4-strokes do. You may also be able to tell by the size of the motor - for a given horesepower rating 4-stroke engines tend to be larger and heavier.
Is 2 stroke or 4 stroke quieter. At present four strokes remain up to 50 quieter than most two stroke engines and they are more efficient than two stroke engines. On average 2 stroke outboard motors are lighter than 4 stroke outboard motors.
2 stroke outboard motors have fewer parts and moving pieces than 4 stroke motors. 2 stroke outboards are smaller and lighter than their 4 stroke of an equivalent power. Due to them being mechanically simpler with fewer major parts to degrade or go wrong the are easier to maintain to a.

The main disadvantage of a four-stroke motor is its size. Larger and heavier than its two-stroke counterpart four-strokes are more expensive to build although manufacturers are. Four-stroke motors are cleaner smoother and more economical.
Many people who run in lakes and rivers prefer 4 stroke boat motors because they make great trolling motors and meet the 2006 EPA mandated requirements. Others prefer 2 stroke engines when the need for top end performance and acceleration takes precedence. Boat Music Outboard Motor - 4 Stroke One noticeable difference between 2-stroke and 4-stroke engines is weight of a similar horse powered engines.
4-strokes tend to be heavier than a 2-stroke engine of comparable horse power. 2-stroke engines uses a gas and oil mixture while a 4-stroke burns gasoline. Which is better 2 stroke or 4 stroke.
Today we look into some of the pros and cons of the 2 stroke engines and the 4 stroke outboard engines. 2 strokes are f. As we all know one of the biggest differences between the two types of motors is how you put oil in the system.
In a two-stroke motor the gas and oil are mixed while in a four-stroke the oil is contained in a separate compartment. Two-stroke oil costs more but is it really worth the extra money. The simple answer is yes.
For a few decades their top-grade engines managed to grab peoples interest. The performance of their motors is pretty much comparable with Yamaha which tells you the reliability of Suzuki. So yes if you are concerned about their trustworthiness you can rely on both the brands.
Suzuki 4 Stroke Outboard Vs Yamaha. People are well aware of. In a 2-stroke engine all the four stages of a power cycle are completed in just two strokes of the piston while in a 4-stroke engine all the four stages of a power cycle are completed in four strokes of the piston.
2 stroke vs 4 stroke. Outboard 2 stroke vs 4 stroke - fuel consumption. Evinrude 2 stroke Mercury Optimax 2 stroke Mercury 4 stroke Yamaha 4 stroke.
Generally the 4 stroke engine will be relatively cooler as compared to 2 stroke engine for same duration of operation. Generally 4 stroke engines will be liquid cooled while 2 stroke engines will be air cooled. Lubricant consumption in 4 stroke will be lesser than as compared to 2 stroke engine.
