Can you still buy 2-stroke outboard motors?
Yamaha and Mercury have stopped producing direct-injection 2-stroke outboards (Tohatsu still builds a few), but the latest-generation 4-strokes weigh the same as 2-strokes and offer the latest digital advances.
Do they still make 2 cycle boat motors?
Today, manufacturers like Mercury Marine have developed 4-stroke outboards that weigh and perform comparably with 2-storke 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.
Are 2-stroke boat motors good?
Because a 2-stroke engine only uses two piston strokes to generate one revolution of crankshaft power, it generates much more power than a 4-stroke engine of the same horsepower. This gives 2-strokes better top-end speed and acceleration. 2-stroke outboards are ideal for use on smaller boats.
What is the lifespan of a 2-stroke outboard?
A typical two-stroke or four-stroke outboard engine should provide 1,500 hours of run time. Based on the average use of 200 hours per year, this will last 7-8 years. However, changing your oil every 50 hours of operation and regularly flushing the engine can see your outboard engine last 10 to 20 years.
Why are 2-stroke engines banned?
Read more on air pollution in India The exhaust gases from two-stroke vehicles also form potentially toxic ‘reactive oxygen species’, it notes. To understand whether banning two-strokes can have any impact on pollution levels, the researchers conducted field studies in two cities of China—Guangzhou and Dongguan.
What is the lightest 70 hp outboard motor?
Yamaha’s new F70 is not only the lightest four stroke 70 horsepower outboard, it’s even lighter than competitive two stroke direct-injected outboards.
Is a 2 stroke or 4 stroke better?
Two-stroke engines are typically noisier and produce more exhaust fumes, but also produce more power compared to their weight than four-stroke engines, making them popular for racing.
Is a 2 stroke outboard faster than a 4 stroke?
A 2 stroke outboard motor has a faster pick-up speed than a 4 stroke. However, once running, both offer speed and power. The make and model of your outboard motor will be the biggest determining factor as to how fast your motor can run.
Why do boat motors not last long?
First, diesel engines typically last longer than gasoline engines. There are two main reasons for this. One, at a given boat speed they turn fewer revolutions, usually about a third fewer. When an engine turns fewer revs per mile, pistons make fewer trips up and down the cylinders and valves open and close less often.
Will 2-stroke outboards be banned?
Two-stroke engines are not “banned” for use on all waterways in California, nor is there any plan to do so. Carbureted and electronic-injection two-stroke engines are considered high-emission engines.
How do I know if my fuel is 2-stroke or 4 stroke?
The easiest way to tell a 2-cycle engine from a 4-cycle engine is the number of fuel tank and/or oil sump fill ports. A 2-cycle engine has one fill port with a cap that has fuel pump and oil can icon. The cap will usually state the oil to fuel mix ratio.

Why are boats so unreliable?
Why are boat engines unreliable? Many boat engines are “unreliable” because they are not taken care of correctly. While some boat engines are less reliable than others, there are common engine issues that appear from overuse, ill-maintenance, or low-quality materials.
Is 1000 hours on a boat a lot?
According to industry people and experts, 1000 hours is the maximum mileage for a used boat you’re considering purchasing. The truth about boat hours, however, is much more complex and depends on so many other decisive factors. The quality of a boat is probably the first thing to consider when looking at the hours.
How often should you change spark plugs on 2 stroke outboard?
PartsVu recommends religiously inspecting your spark plugs annually or every 100 hours, replacing them if they are fouled or damaged, and always replacing them every 300 hours.
