How can you tell the difference between a 2 stroke and a 4 stroke outboard?
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..

How many hours can you get out of a Yamaha 4 stroke outboard?
From what I’ve seen most 4-strokes are problem free up to about 1000 hours and then with minor repairs easily make 2000+ hours. I was shown an ECM printout by a dealer at a boatshow from a Verado 225 that had 4300 hours on it.
Why are 2 stroke engines banned?
Answer: Two-strokes left the market because they could not meet steadily-tightening EPA standards for vehicle exhaust emissions. … A four-stroke engine has a separate piston stroke for each of the four functions necessary to a spark-ignition engine: intake, compression, power, and exhaust.
Can you put two stroke oil in a four stroke engine?
The two stroke oil will not hurt your four stroke mower in the least. … In fact, the 4 stroke engine will pollute less burning 50:1 than a 2 stroke using the same fuel. This is because the valve system on a 4 stroke provides more complete burning. You better never run 2 stroke on pure gas, though…
Is a 2 stroke engine faster than a 4 stroke?
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. That being said, 2-stroke engines are more powerful.
How long will a four stroke outboard last?
2,000 hoursFour-stroke motors boast lower operating costs, are more environmentally responsible, and are generally quieter than two-stroke engines. These motors can run over 2,000 hours before looking into major repairs. Even longer with proper maintenance.
Is Suzuki better than Yamaha?
Suzuki is the better all-rounder, but their bikes come across a bit bland. By now they shook off the old perception people have about them being a “discount Honda”, but I wouldn’t say that any of their bikes are class-leading. Yamaha on the other hand, makes A+ stuff and D stuff.
What is considered high hours on a 4 stroke outboard?
Big 4 strokes are good for 5,000 to 6,000 hours.
Why are two stroke engines more powerful?
Because combustion takes place with each revolution of the crankshaft with a 2-stroke, this format puts out more power than a 4-stroke engine and the power has more instantaneous delivery. This are some reasons why 2-stroke engines have a long history of use on many different types of motorcycles.
Which is better a 2 stroke or 4 stroke outboard?
Fuel economy and speed are comparable between two-strokes and four-strokes. Two-strokes tend to weigh less but can accelerate faster. Four-strokes tend to be quieter and have more torque than two-stroke outboards.
