No. There is a oil tank much like your car that you top off.
NO! definitely a 2 stroke and requires oil in gas.
From the oil you mix in with the gas
Its 4 stroke so 100:0
50:1
With a 2 stroke engine, you mix the oil with the gas. With a 4 stroke engine, there are separate tanks for the oil, and the gas.
probably 50:1
50:1 oil mix is typical for outboard two-cycles. Some do a little more in the winter.
Does it have valves (4 stroke) 2 stroke has ports Do you have to mix gas/oil (2 stroke)
Instead of buying a new boat, the best alternative may be simply purchasing a new motor. For those that have fishing boats and other working craft, he or she probably has an outboard motor, which are popular on these particular vessels. Outboard motors can be found in a number of places although it is best to purchase one from an authorized dealer or someone that is trustworthy. The reason for this is that simply outboard motors require special knowledge of engine parts to repair and refurbish. If the proper care and time is not taken for the repair, the motor could fail at the most inopportune time.Four Stroke EnginesThe most popular outboard engines of the present are the quiet and reliable four-stroke engines. These engines have recently made their debut over the last ten years because of their ease of use. Four-stroke engines do not use oil as two-stroke engines do, and they also use less gas than two-stroke engines. Also, the four-stroke engine is much quieter than the noisy two-stroke engine, which makes it far less intrusive for those long trips to the Gulf Stream. The only down-side to four-stroke engines are that they are more expensive than two-stroke engines. Four-stroke engines are also considered safer to purchase from classified advertisements or other places. Four-stroke engines do not require specialized repair personnel for general maintenance and small repairs. A 150 horsepower engine can be found for prices starting at $5000.Two Stroke EnginesTwo-stroke engines are the most traditionally used outboard motor on the market. They incorporate the use of oil in their gas tanks and are said to be able to attain more overall torque than four-stroke engines. Two stroke engines are great engines and can be found re-built for relatively cheap. For instance, $500 will get one a two-stroke outboard motor up to fifty horsepower. The best place to look for two-stroke outdoor motors are at authorized used boat dealers or licensed small engine repair shops. Two-stroke engines are different from other engines and takes one with specialized knowledge to make even the most general repairs.
The 1998 model Mariner outboards use a 50:1 ratio.
50:1, ie 50 parts gas to one part two stroke motor oil. So for every litre of gas added, you add a further 20ml of oil.
The sticker on the side of my 6hp two stroke Suzuki OB reads 100 to 1. Unsure of the year.
