2 stroke vs 4 stroke boat motor

Because 2-stroke engines are designed to run at a higher RPM they also tend to wear out faster. The 4-stroke engine is also much quieter a 2-stoke engine is significantly louder and has a distinctive high-pitched buzzing sound.

2 stroke vs 4 stroke boat motor. In years past 4 stroke motors were not as sporty and performance-oriented as 2 strokes. 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.

Today manufacturers like Mercury Marine have developed 4-stroke outboards that weigh and perform comparably with 2-stroke outboards. And by using direct injection techniques Mercury Marine is also making 2-stroke outboards that are as clean running smooth and quiet as 4-stroke outboards. Being heavier and more cumbersome could make a 4-stroke outboard incompatible with smaller boats better served by a lightweight 2-stroke engine.

The 4-stroke motors lubrication system requires periodic maintenance including replacing the oil and filter whereas a 2. 4-stroke motors differ in their piston movement as it features 1 compression stroke a return stroke an exhaust stroke and another return stroke. The purpose of the exhaust stroke which is not used in 2-stroke motors is to release the spent gas fumes through the exhaust.

In general 4 stroke motors are quieter and use slightly less fuel. In other words will the 2 stroke boat motor win the match and deliver the final upper jab blows to the 4 stroke or will the 4 stroke steal the show in another way entirely. That is what we are going to look at and we have been asking this question for many years as boat owners so it is high time that we take a bit of a close look at it.

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. A two-stroke engine works in different orientations.

This factor makes it a more robust engine than the four-stroke engine. The construction of a two stroke engine is less-complex than a four-stroke engine making it a cheaper option. 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. The 2-stroke engine produces higher torque at a higher speed rpm.

The 4-stroke engine produces less torque at high speed rpm. It cant produce higher torque at low speed rpm. This engine produces higher torque at low speed rpm.

A 2-stroke engine has. 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. Posted November 22 2013. On 11212013 at 532 PM 00 mod said.

Hey slone 4 stroke should get better gas mileage. Also a fuel injected 4 stroke will be muxh less finicky in extreme temperatures. Based on my research when I bought my boat the ProXS fuel consumption and top end was better than the Verado.

Additionally two-stroke engines are less fuel-efficient get fewer miles per gallon and produce more emissions than four-stroke outboard motors. A four-stroke engine works by running one compression stroke followed by an exhaust stroke. All critical factors in outboard engines.

While 2 stroke outboard motors are typically not maintenance free servicing is fairly cheap and easy to fix when issues arise. 2 stroke outboards are smaller and lighter than their 4 stroke of an equivalent power. Deciding to change an old 2 stroke outboard for a new generation 4 stroke engine was a no-brainer for Thomas Ansorg and the results certainly prove it.

When Thomas Ansorg went looking for a second-hand boat he could use as a workhorse out on Great Barrier Island he knew he needed something tough and rugged. But he also wanted reliability so an engine change was called for. 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. 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.

I know the 2-stroke vs. 4-stroke argument has been worn out but I am looking for an upgraded boat something about 10 years old to get in my price range Ranger Skeeter Triton etc Lots of good boats out there for sale and I am assuming they will really start showing up. For example two-stroke motors are lighter faster in most cases and less expensive.

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. Outboard 2 stroke vs 4 stroke - fuel consumption.

Evinrude 2 stroke Mercury Optimax 2 stroke Mercury 4 stroke Yamaha 4 stroke. Because the ports on either side of the cylinder do not have valves there is less mechanical hardware with a two-stroke motor and as a result there are less moving parts no valves valve springs or cams. This results in a lighter weight than a comparable four-stroke motor.

Fly Navarro joins the crew at Florida Detroit Diesel to discuss the differences pros and cons of 2-stroke VS 4-stroke diesel engines for sportfishing boats. Check out the advantages of modern 4-stroke diesel engines. Fly Navarro will take us to the Fly Zone with his vast knowledge and list of fishing connections.

Vehicles like cars trucks and some motorcycles have four stroke engines. Other applications are small propeller aircraft formula one small motor-powered boats auto-rickshaw water spray systems etc. They all have a four-stroke engine.
