2 Cycle Oil | Outboard Motor Oil - Part 25

History of Outboard Motors

History of Outboard MotorsThe creation of the first practical outboard motor is often credited to Norwegian-American inventor Ole Evinrude in 1909.

Historically, a majority of outboards have been two-stroke powerheads fitted with a carburetor due to the designs inherent simplicity, reliability, low cost and light weight.

In the 1990s, U.S. and European exhaust emissions regulations led to the proliferation of four-stroke outboards. Though fewer in number, four-stroke outboards have always been with us.

Outboard motors benefit from the ability to draw coolant from the water, obviating the need for radiators and cooling fans, thereby simplifying the design and lowering component weight. The motors also have several brands (i.e. Yamalube, Mercury and the creator’s namesake, Evinrude) of oil to choose from, giving the consumer a seemingly infinite amount of options based on their needs.

Picking the Proper Two-Cycle Oil

Two-Cycle OilTo understand how two cycle oil works in your engine, we need to cover some basic information on engine operating conditions and oil formulation. Outboard engines are characterized by their constant speed, high output operation. They are usually set at a desired high speed and continue at that speed until the destination is reached and then throttled down. Also, they are constantly cooled with fresh, cool, non re-circulated water.

Chainsaws, on the other hand, are a high action operation. They are constantly started and stopped, used for short periods, and frequent overloads are its hard place in life. Additionally, they have smaller displacements than outboards and are air cooled. By understanding how the operation of an engine can affect the oil used and how oil can affect the engine, we can better appreciate the difference between a water cooled two-cycle oil and one formulated for an air cooled two-cycle engine.

What is Two Stroke Oil?

2 cycle oil

Two-stroke oil (also referred to as two-cycle oil, 2 cycle oil, 2T oil or 2-stroke oil) is an engine oil intended for use in two-stroke engines, like those in many lawnmowers, Outboard motors, mopeds, scooters and small capacity motorcycles, etc. Since these lightweight engines do not feature oil sumps to collect and recycle oil like 4 cycle engines, oil must be mixed with the petrol fuel, for distribution throughout the engine for the purpose of lubrication. The two-stroke oil is ultimately burned along with the fuel resulting in exhaust emissions such as blue smoke and a distinctive odor.
