2 Stroke vs. 4 Stroke Outboard Motors: A Guide for 202

  1. 2 Stroke vs. 4 Stroke Outboard Fuel Economy. In the past, 2 stroke motors burned more fuel than 4 strokes. However, the 2 cycle product is now much more efficient in its injection methods used to bring fuel into the engine. Some companies claim to be more fuel efficient than others, but in many cases, it's a matter of splitting hairs
  2. 2-Stroke Outboard vs. 4-Stroke Outboard Final Word. The pros and cons of 2-stroke and 4-stroke outboards might seem straightforward, but the technologies behind both engine types are very advanced these days
  3. One topic that keeps popping up concerning outboards is the comparison between Two Stroke Vs. Four Stroke Outboards. So much is being said about both types of engines, that it is worthwhile to take a closer look at the more delicate points of these two different types of outboards to get a better understanding of each one

Traditionally, because of the simplicity and light weight, 2-stroke outboards have dominated the outboard market. It is widely understood that modern 4-stroke outboards are quieter, produce less vibration and create significantly less pollution. However, until recently, due to expense and weight, 4-stroke outboards were not widely accepted 2 Stroke vs. 4 Stroke Outboard Motors: What Buyers Should Know. Boat owners considering purchasing a new outboard motor often have questions about the difference between a two-stroke and four-stroke outboard motor. Many people immediately assume that a two-stroke is less powerful and, therefore, less desirable. This isn't necessarily true Difference Between 2-Stroke Vs 4-Stroke Outboard Motors by Consumer Reviews [2020 Updated] Last Updated : October 28, 2020 Although people believe that a two-stroke outboard motor is more efficient and powerful compared to a four-stroke motor board, it is essential to know that these two units work perfectly well 2 Stroke Vs 4 Stroke Outboard Motor Function 2 Stroke Outboard Motor Function. According to Wikipedia, A two-stroke (or two-cycle) engine is a type of internal combustion engine which completes a power cycle with two strokes (up and down movements) of the piston during only one crankshaft revolution

Two-Stroke Vs. Four-Stroke Outboards: Advantages ..

However, a 2-stroke outboard will burn through a lot more oil in a season than a 4-stroke, so the running costs are higher. 2-Stroke Outboard vs. 4-Stroke Outboard Performance Final Word Based solely on the mechanical design and workings, the 2-stroke has the edge when it comes to acceleration and top speed, while the 4-stroke is better on. Comparing fuel efficiency is a good starting point. The first thing to keep in mind is that both 4-stroke and direct injection 2-stroke outboards on average are more than 35 percent better than traditional carbureted 2-strokes on fuel consumption, according to Tom Mielke, outboard marketing director for Mercury Marine 4 stoke outboards are heavier than an equivelent 2 stroke with the same power, often due to their larger relative size. 4 strokes are more mechanically complex around power block and head so consequently to a higher level of skill to maintain and repair 4-Stroke Outboard Motor Vs a 2-Stroke Outboards.

2 Stroke Versus 4 Stroke Outboard Boat Motor Compariso

Since a 2 stroke has twice as many firing strokes per 1000 revs than a 4 stroke but each power stroke is less efficient, the two have quite different power characteristics. But in something as mundane as an out board, the power developed is much more a matter of what the engine designer designed 2 Stroke vs 4 Stroke. The difference between 2 Stroke and 4 Stroke is basically how they are operated. The 4 stroke engines require a heavy flywheel, whereas 2 stroke engines require a lighter flywheel.Both the engines can also be differentiated on the basis of their use because 2 stroke engines are mainly used in scooters and mopeds whereas, 4 stroke engines are used in heavy vehicles or off.

Yamaha outboards listed weights are amazingly light. I am curious if they are close to what they claim. The new mercury 150 4 stroke is listed at 455lbs. That is very light for a 4 stroke too. Weights for 4-strokes and 2-stroke G2s have converged, but I think the G2 weight includes the internal steering feature which adds 30ish pounds Two-stroke outboards vs four-stroke. For example, if you've spent $2500 on an old 3.7m tinny and trailer, there's no point in spending more than that on a new engine. Anymore and you've over-capitalised on the rig and you'll make a loss when it comes time to trading up. Also, the weight of a four-stroke 15 may be 40 per cent more than a. 2 stroke Vs 4 stroke outboard motor. If you own a boat or have ever looked at buying one, the engine on it will have been described as either a 2 stroke or a 4 stroke.In this post we'll have a quick look at the mechanical differences for those that are interested or just skip down to the characteristics if that's all you're looking for A 4-stroke Outboards takes longer to warm up, has as a greater reciprocating mass than its 2-stroke equivalent and is far more sensitive to the warm up period being properly completed. Any engine put under load before it reaches its optimum operating temperature wears very much faster, but it affects 2-strokes far less

2 Stroke Vs 4 Stroke Outboard Motors L & M Marine

I replaced a 2 stroke Johnson on a 23 1/2 foot Pursuit with a 4 stroke Yamaha and it made a huge difference as far as how far I could run and how long I could afford to stay out. That engine sipped fuel where as the 2 stroke guzzled it even though it was a fuel injected engine as well My 2 stroke is very fuel efficient (way less gas than a Verado and doesn't need premium fuel like a Verado) and doesn't smoke. Both the Optimax and ETECs get better mileage than most 4 strokes. These aren't great grampa's 2 strokes

Outboard brackets: 2-stroke vs 4-stroke New Topic Topic Locked Printer Friendly: Author: Topic : Lee Panza Captain. USA 433 Posts. Initially Posted - 03/11/2011 : 12:51:29 . I'm about to buy a new motor, and of course it'll be a 4-stroke and heavier than the one that's on my boat, so I've been looking into buying a new mounting bracket. What I. For example if I were running a 4 stroke and had my engine serviced every 100 hours, I would be looking at 5 services a year @ approx $800 each. My 2 stroke however has negligible servicing requirements and only requires a plug change and gearbox oil every 300 hours. This is the sort of thing you can do yourself re: Outboards: 2 stroke vs. 4 stroke Posted by DownshiftAndFloorIt on 7/11/13 at 3:28 pm to LouisianaChessie 2 strokes don't do much better than fours anymore except rev higher with exploding and weigh less

ETEC HO's and Mercury Pro XS outboard motors are 10% underrated on horsepower and will be maybe 3 mph faster on top end than the same hp 4 stroke. If someone's into water sports, going with the next smaller size 2 stroke ETEC HO or XS Pro is a good value option because 2 strokes are so strong in acceleration We went from a Malta 3 hp 2 stroke to a Suzuki 6 hp 4 stroke, big mistake. Much heavier engine, slow on acceleration compared to 2 stroke and noisy at high revs + the paint fell off it just out of warranty. Sold that and bought a 9.8 2 stroke Tohatsu which is the same weight, quieter and of course much faster It's tough to know whether a modern DI 2 stroke vs. a modern 4 stroke is a worthwhile argument, or is simply different sides of the same (similar?) coin. If I were in the market for a new outboard, my primary considerations would be dependability and longevity 2 stroke E-Tech, VS 4 stroke outboards (40-60hp) somann. Participant. Posts: 16. January 29, 2007 at 4:37 pm #1234786. But more maintence does come with a 4-stroke over your simple 2-stroke carb motors. There is also a price-tag that is a bit higher to add into the compensation Re: 2 Stroke vs 4 Stroke Outboards, Pros and cons? by k2nickmn83 » Tue May 21, 2013 1:23 pm yeah, at the moment its coming down to what i can find for a fair price on a good motor, the used 4 strokes in my area are demanding pretty high used price

2 Stroke vs 4 Stroke Outboard Motors New and Improved

2-Stroke - The way outboards - dirt bikes - and weed eaters have always been make - you have to add 2 cycle oil to the gas before combustion (either direct injection or mixing in the gas) I've always had one and if it ain't broke don't fix it. Quote; Link to post Share on other sites. slonezp 12,34 I wouldn't hesitate getting either the 2 stroke or 4 stroke if it was the right hull, just looking for some input on this new motor that isn't a commercial for it. I would love hearing input from the smaller sized engines like 150 and 200 as well. Re: Mercury 250 pro xs 4 stroke vs 2 stroke. 4-Stroke Outboard Motor Vs 2-Stroke Outboard Motor The decision to purchase an outboard engine is getting more selective as technology improves. As of now the majority of consumers are faced with several options when deciding upon what kind of outboards will best suite them 4-Stroke Outboard Motor vs 2-Stroke Outboards. MDC said: A friend told me 4 stroke outboards are faster than a 2 stroke motor that is similarly rated in terms of horsepower. Do any of you know this to be true? I am looking to replace a blown 40 hp 2 stroke Mercury with a 4 stroke on our 15' Seaswirl

Yamaha says its performance benchmarks for the VF150 were those of its V MAX 150 HPDI two-stroke, and claims it is indeed faster (57.2 mph vs. 56.8 mph on a Skeeter ZX190) and quicker than that model and its standard F150 four-stroke Thanks for the post. I guess my comparison would have been a 40 horse Johnson 2 stroke VS a 40 horse Johnson 4 stroke, and the relative power or speed when the two are compared. My point was that two motors of equal horespower, but one of each of the two stroke options, have the same power. Or real close used outboard (two or four stroke) new 4 stroke outboard new direct fuel injected 2 stroke outboard; Each have several different main features, for example two stoke outboards are lighter, faster (in some cases) and less expensive. Four stroke motors are cleaner, smoother, more economical, great trolling motors and meet environmental requirements Another area in which Evinrude outboards has excelled in its new offerings it the maintenance aspect. Despite the higher cost of 2-stroke as opposed to 4-stroke oil, maintaining these engines works out at about 50% the cost of a 4-stroke engine. Evinrude offers a minimum 3-year warranty on its products, with up to 5 years on the G2

Typically, 2-stroke engines rev up to higher speeds than 4-stroke engines, and this accounts for much of the higher power per pound, Parish says. Also, small 2-stroke engines use intake and exhaust ports instead of valves, thus saving the weight and cost of a valve train Tohatsu offers the best outboard motors, including the 115 hp outboard, 150 hp outboard, 200 hp outboard, 225 hp outboard and the 250 hp outboard. These Tohatsu 4-stroke boat motors have outstanding features that provide boaters with unmatched technology, proven reliability and the big power you have been waiting for. Click each outboard boat engine above, from 115hp to 250hp, for more. I've been looking hard at 60 HP outboards and when you compare the ETEC to the Suzuki a purpose built 4 stroke for outboard use, and any advantages a 2 cycle has is getting smaller, weight for instance, they weigh the same. I think in 2-3 years we wont even be having these conversations, what will be interesting to see is if BRP continues to. 2 stroke vs 4 stroke maintenance: Any 2 stroke is going to be easier to maintain if you are handy with the spanners but could require more regular fixing up if you spank it like you are supposed to. Yes, a 4 stroke is a little more expensive to run, but even a 4 stroke can be fixed up at home if you like mechanical work

Two-Stroke vs Four- stroke Outboard motors12/10/2012 1 2. History• The first outboard motors were invented around 1870 by Gustave Trouve'• Evenirude was the first most successful outboard motor and offered a two- stroke motor with 3 hp created by Ole Evenirude• Honda was the first company to introduce four- strokes to the marine. In 1984 the first 4 stroke motors hit the market, which made Yamaha an industry leader. Through consistent innovation and development, Yamaha has continued to develop their line of outboard motors. Today, customers have their choice of 4 stroke motors from 2.5 to 425 horsepower motors. Mercury vs Yamah When choosing 4 stroke outboards - depending on the horsepower range you need for your craft - one of the decisions you'll need to make is whether you want an electronic fuel-injected (EFI) engine or a standard, carbureted 4 stroke. From the Start. First, when it comes to starting 4 stroke outboards, an EFI engine has the advantage Suzuki 4 Stroke Outboard Vs Yamaha. People are well aware of Yamaha. Suzuki, on the other hand, doesn't have that number of die-heart fans, which can be the reason why people don't know much about Suzuki outboard motors. Let's put Suzuki and Yamaha head to head and see which one dominates the most regarding some key aspects of an outboard.

i have two images here that i have found on the web from a quick search that show the power and torque curves of a 2 stroke vs a 4 stroke 150hp modern outboard motor. This is probably some of what jimh uses to come to the conclusion that a 2stroke raches peak power earlier (around 4500 rpms) the the 4 stroke (around 5500 rpms) I am not sure who. Comparing 2-Stroke vs 4-Stroke. As you can see there are definitely a couple of advantages to owning a 4-cycle motor for a trimmer or other lawn care application, but for the most part, there is a reason 2-cycle motors are currently king. They are simply reliable, have less to break, and are much easier to start and use That 4-stroke costs less than a comparably fast 2-stroke plus a new block for the 2-stroke about five years from now. If lyou buy a 4-stroke OB whose engine is based on an automobile engine (again Honda), most of the parts can be purchased through automobile parts channels rather than the more expensive marine suppliers

Should you buy a Two Stroke OR Four Stroke Outboard Engine

Usually two wheeler engines are easier to identify since most of them are exposed. The easiest way to identify a 4 stroke and 2 stroke engine just by looking at it is to see where the inlet goes to, that is, where the carburetor is attached. If it.. 2) after 2 years the 4stroke would need a major top-end rebuild causing the 2 stroke to be cheaper after the end of 2 years of riding. I calculated this by looking at cost of maintenance and manufacturer's recommended service intervals

The 2 stroke either takes it in the fuel (recommended) or it is injected with the fuel from a reservior. Fuel efficency on a 2007 model 2 stroke is just as good as a 4 stroke. You will not the hole shot out of a 4 stroke that you will a 2 stroke so it all depends on what your using the boat for Two-stroke engines are generally less expensive to build compared to four-stroke engines, and they are lighter and can produce a higher power-to-weight ratio. For these reasons, two-stroke engines are ideal in applications such as chainsaws, weed trimmers, outboard motors, off-road motorcycles and racing applications RE: 2-Stroke Vs. 4-Stroke Outboard (75-90HP) I'll tell you guys a sad story on the BWCA.pipestone bay I was using a friends 15 horse evinrude 4 stroke and when he had a oil change done on it the guy cross threaded the oil filter and it came off up there when we were runing wide open.Let me tell you my heart sunk when I saw that oil slick. Backed by decades of marine power innovation and product leadership, Mercury FourStroke outboards (2.5hp to 300hp) deliver legendary performance and forward-thinking technology. Serious benefits for serious boaters. The new V8 and V6 FourStrokes offer everything you need for a boating experience that exceeds expectations: Power. Speed. Efficiency

Except the thread is called '2 Stroke vs 4 Stroke mower' so it's a valid comparison, some would say moreso than arguing about motorbikes. Somewhere back in the thread people started to debate which had more torque/power. It's relevant and good to have the facts out there YAMAHA YZ250FX 4-STROKE vs. YZ250X 2-STROKE: FULL TEST. Share Facebook Twitter Google+ ReddIt WhatsApp Pinterest Email. Yamaha is in the position of offering two completely different 250cc off-road bikes for the same purpose. The YZ250FX four-stroke is based on the previous generation of YZ250F motocross bikes but with electric start, a six.

If you want a larger power boat, an inboard/outboard is the best choice. In regards to outboards: My best recommendation for a 2-stroke would be an Optimax from Mercury. These engines are direct injected engines, and have superior performance to all other 2-strokes on the market. The Optimax blows that e-tec from Evinrude out of the water If your 2-stroke is working great, there's certainly no reason to make a change. 4-stroke technology is more complex than 2-strokes, so chances are good that you'll spend more to have your engine maintained by a professional marine mechanic. If you're used to servicing your 2-stroke outboard yourself, that could be a drawback

Just to add to the mix, look at outboard motors. Water cooled, fixed power levels, steady state operation. Can be had in 2-stroke and 4-stroke. Probably the most advanced 2-strokes around (direct inject and such). The 2-stroke outboards I can think of work real good, only issues are running them without oil Maintenance & Repairs | 2-Stroke vs 4-Stroke. A 2-stroke engine requires more frequent basic maintenance. This is because the lubricating oil is mixed with the fuel. One reason for this, is the increased carbon produced during combustion. The carbon from the burnt oil collects on the spark plug. This requires more frequent cleaning of the spark. Hafiy displays both 2-stroke and 4-stroke outboard motors. The 2-stroke model produces 3.6 hp and comes with a cooling water system. The 4-stroke produces 4hp and has air cooling system. So evidently, both models do not lack the horsepower to give you significant speed. The rest of the features are similar for both models A reply to my post about 8hp 2-stroke vs 6hp 4-stroke said a 2-stoke has more torque. At max RPM, they're about the same for a given hp rating, since they both achieve that at the same RPM. Torque at low RPM is not significant for the bracket, since the most stress is at max RPM. The OP said he's mounting a 4-stroke 5hp on a bracket rated for 20hp This went all the way from power comparison of 2-stroke and 4-stroke engines to what paint to use when coloring your engine.

On the used market, there is of course a big price difference between old 2 strokes, DFI/EFI 2 strokes, and newer four strokes. Real world, how much of a difference is there? From reading performance bulletins from the big outboard manufacturers there seems to be anywhere from 15% to 50% reduction in fuel usage Mercury/Mariner 25 HP Bigfoot/Command Thrust - 60 HP Outboards. 25 HP Bigfoot/Command Thrust (CT) (4-Stroke) 30 HP 2-Stroke; 30 HP BigFoot/Command Thrust (CT) 2010 & Newe Four stroke outboards. Although four stroke outboards have been sold since the late 1920s, particularly Roness and Sharland, in 1962 Homelite introduced a commercially viable four cycle outboard a 55-horsepower motor, based on the 4 cylinder Crosley automobile engine. This was called the Bearcat and was later purchased by Fischer-Pierce, the. Two-Stroke or Four-Stroke . A common test to compare and contrast different engines is the stroke test. Traditionally, there is a big difference between the two kinds of engines. Two-stroke engines are considered to be more powerful than four-stroke engines, while the latter is considered to have a cleaner fuel output

Still, the 4-stroke might not be the right repower choice for all boats, especially those that are about 12 years old or more. Older boats designed for 2-stroke power may lack the buoyancy in the stern to support a 4-stroke. And an older 225-hp 4-stroke can weigh nearly 600 pounds. Model year matters A rough rule of thumb is to go up one or two sizes (46 2 stroke becomes a 56 or 62 4 stroke). I also like more than enough power. so for most of my 46 size planes, I use Saito 72's or 82's. Haven't found it to be a problem yet. The difference in weight and physical size between say a 56 and an 82 is minimal 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

2 Stroke vs 4 Stroke Outboard Motors: A Side by Side

The 2-stroke outboard differs from the 4-stroke outboard in that there are only two movements that go up and down instead of four. The 2-stroke engine generates its power with two movements of the piston during one crankshaft revolution. A four-stroke engine needs four movements to generate power In this post, I am going to tell you about the difference between two stroke and four stroke engines. The main difference between them is that in 2 stroke engine the crankshaft revolves two times to complete its working cycle whereas in 4 stroke, the crankshaft does 2 revolutions to complete its working cycle T9.8 Outboard Motor 4 Stroke Vs Outboards 2 Stroke For Pvc Fishing Boat , Find Complete Details about T9.8 Outboard Motor 4 Stroke Vs Outboards 2 Stroke For Pvc Fishing Boat,Outboards 2 Stroke,Outboard Motor,Pvc Fishing Boat from Boat Engines Supplier or Manufacturer-Zhejiang Cang Long Power Machinery Co., Ltd Adjustable outboard motor bracket is designed for 2- and 4-stroke motors up to 15 HP or 132 lbs.

Ok the ?? is buy a 25 4 stroke or 2 stroke?? the difference in price is amazing a 4stroke Mercury cost $3,400 and a 2 stroke $2,200. The positive of the 4 is no smell, no smoke, less noise the negative a little bit more heavy and very. Two-stroke has more torque and is lighter. Downside they can be oily, noisy, and hard to start. Personally I prefer a 4-stroke because I like an internal combustion engine to stay clean, start quickly, and run quietly. The principle of a 4-stroke makes sense to me. But how the hell a 2-stroke even runs baffles me The two stroke outboards are lightweight and compact yet deliver high power output. The engine structure is relatively simple and maintenance is exceedingly easy. Although we have lineup of four strokes, we also offer an extensive two stroke lineup to meet diverse global needs. The lineups of. I can buy a 2 stroke Yamaha 25 installed for $2900. The same dealer has a 4 stroke Yamaha 30 installed for $5200. The performance would be about the same with either motor.
