What is the gas to oil ratio for a Mercury outboard?
As a general rule of thumb, add three ounces of Mercury 2 stroke premium outboard motor oil for each gallon of gas. Pour the gas and oil into a singular container. Close the gas container tightly and then shake the container vigorously to ensure that the oil and gasoline mix thoroughly.
What octane gas should I use in my outboard?
“The best thing you can do for any motor is buy gas of known, high quality,” says David Grigsby, Yamaha’s product manager. “We recommend 87 octane for both our two- and four-stroke motors.
Should you use premium gas in outboard motor?
Burning 87-octane gasoline in a two-stroke outboard causes carbon buildup that shortens engine life. Dose the fuel with a carbon-cleaning additive or fill the tank with 89-octane or higher fuel.
Is a 2-stroke outboard faster than a 4-stroke?
Since the two-stroke isn’t encumbered with a valve train, the engine has fewer moving parts. Thus, it has less rotating mass. A two-stroke outboard can often accelerate faster than the same horsepower four-stroke.
Is a 4-stroke more powerful than a 2-stroke?
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. That being said, 2-stroke engines are more powerful. Two-stroke engines are a much simpler design, making them easier to fix. They do not have valves, but rather ports.
What is faster 250 2 stroke or 450 4 stroke?
The 250 exhausts you quicker both physically and mentally, but if you can swing it, a ride on the 250 2-stroke prior to a showdown on the 450f can actually make you a better rider and more competitive on the track.
Which is cheaper to maintain 2-stroke or 4 stroke?
While two-stroke engines run more simplistically, their need for maintenance is usually much higher. However, two-stroke parts are notoriously cheaper than four-stroke. Two-strokes also require more frequent shifting, but riders can get a faster top speed with more power.
How long does 2-stroke engine last?
I would guess a 2-stroke 250 should last around 40 hours between top ends. That is IF you keep up on all maintenance items — air filter, tranny oil, etc. The how often and how hard matter, but their’s no way to know unless you keep track of the hours you are actually running the engine and riding it.
Why does 2t mean 2 stroke?
Fuel for a 2-stroke engine has a small amount of oil mixed into it. It is called a “2-stroke” because just one up and down movement of the piston—the 2 strokes—performs the full cycle of intake, compression, combustion and exhaust.
What does the T in 2T stand for?

Does 2T mean 2 stroke oil?
Two-stroke oil (also referred to as two-cycle oil, 2-cycle oil, 2T oil, or 2-stroke oil) is a special type of motor oil intended for use in crankcase compression two-stroke engines.
What is the best synthetic 2 stroke oil?
Our top pick for the best two-stroke oil is the Lucas Oil Semi-Synthetic 2-Cycle Oil. It comes in a wide range of different sizes and works well in a number of different two-stroke engines. If you’re looking for our best value pick, check out the Pennzoil Marine XLF 2-Cycle Oil.
