2 stroke vs 4 stroke outboard weight comparison

Another development is the increase in the debate of 2 stroke vs 4 stroke. Weight difference between a 2-stroke 15hp and a 4-stroke 15hp.

These engines are also getting more powerful.

2 stroke vs 4 stroke outboard weight comparison. 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.

More Canadians than ever are enjoying life on the water. The sale of outboard engines is 20 higher than they were in 2010. 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.

Well most banned 2-stroke areas are just banning the premix motors so an oil-injected 2-stroke will likely be OK. Otherwise as was noted the weight difference of a 4-stroke may be offset by going down one motor family size. Say for instance getting a 30hp FI TohatsuNissanMerc.

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-stroke engine simply requires a full tank of oil. Advantages of Two-stroke Outboards.

Two-stroke outboards fire for each revolution of the engine instead of every other revolution as in four-stroke engines. This makes two-stroke outboards more powerful than the four-stroke variety. A two-stroke engine works in different orientations.

This factor makes it a more robust engine than the four-stroke. What is difference between 2-stroke and 4-stroke outboards. 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. Weight difference between a 2-stroke 15hp and a 4-stroke 15hp. The difference between 99 and 15 is usually the ability to plane or not.

The same may be said about the difference between 2- and 4-stroke 15s. The 4-stroke isnt usually as quick as the 2-. But since yours is only rated for 10 you really dont have much choice legally or ethically.

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. 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 98 2 stroke Tohatsu which is the same weight quieter and of course much faster. As far as efficiency goes the 4-stroke certainly wins.

This is due to the fact that fuel is consumed once every 4 strokes. Four-stroke engines are heavier. They weigh upwards of 50 more than a comparable 2stroke engine.

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. 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.

For this reason they tend to be lightweight. Today there are numerous changes and improvements taking place in outboard motor manufacturing and design. 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. Comparison of 2 Stroke vs 4 Stroke Engine.

The following are the major differences between the 2 stroke and the 4 stroke engines. One of the major difference between the 2 stroke engine and the 4 stroke engine is that the method of taking the chargeAirfuel mixture into the cylinder. And exhausting the combustion products from the cylinder.

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.

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. Each stroke is followed quickly by a return stroke.

Most four-stroke outboard motors on the market today. Outboard 2 stroke vs 4 stroke - fuel consumption. Evinrude 2 stroke Mercury Optimax 2 stroke Mercury 4 stroke Yamaha 4 stroke.

Full Throttle RPM Range. Variable Trolling RPM Range. HP Rating at Propshaft.

Alternator Output at WOT. 2 stroke Vs 4 stroke - Yamaha outboard 60hp shootout - YouTube. 2 stroke Vs 4 stroke - Yamaha outboard 60hp shootout.

DFI two-stroke outboards as a rule are still lighter in weight than comparable four-strokes too although the gap between them is closing rapidly. Evinrudes G2 series of direct fuel injected E-TEC two-stroke outboards are available between 150-300hp. If you need speed and are set on Yamaha buy the 90 Yamaha 4-stroke and put the battery in the console to lessen stern weight or just get the Yamaha 90 hp 2-stroke which is probably the lightest 90 out there although not as strong as the OMC 90 2-Stroke.

Posted 04-17-2003 0430 PM ET US. Fuel And Oil Economy. Score another point for 4-strokes which are approximately 50 percent more fuel-efficient than typical 2-stroke outboards.

To be fair advanced 2-strokes have narrowed the gap and in cases when paired with specific boats or running conditions can give 4-strokes a run for their money. 2 Stroke Vs 4 Outboard Motors New And Improved Boater S. Mercury Unveils Innovative 600 Hp Verado Outboard Its Largest Ever Soundings.
