The Ski-Doo 850 E-Tec, manufactured at the company's Rotax factory in Gunskirchen, Austria, was first introduced in 2016 for model year 2017 snowmobiles. It replaced the 800R E-Tec.

180 hp ENDLESS POWER - 850 E-TEC Turbo R: Summit snowmobiles are powered by one of two Rotax 2-stroke engines - including the most powerful factory-built 2-stroke turbo, the 850 E-TEC Turbo R at 180 hp. Each offers instant response and seamless power.

What does E-TEC stand for? E-TEC is not an acronym, it doesn't stand for anything. E-TEC is the name we have chosen to apply to this new technology.

Power beyond fuel and oil efficiency e-tec offers real benefits engines that start on the first time every time even in extreme cold virtually no two-stroke smoke or smell. A super smooth refined idle

Ski-Doo

Snowmobiles almost all follow the basic design of skis, fuel tank, engine, and seating for driver. They are steered by handlebars that control the skis and by shifting the position of the driver. Acceleration and braking are controlled by hand-squeeze throttle and brake controls on the handlebars.

And higher performing ones at mid and high rpm by changing the size of the exhaust. Ports.

Evinrude E-TEC is the best of both technologies. It provides the quiet, efficiency and cleanliness many customers associate with the 4-stroke outboards, combined with the torque, throttle response, quick acceleration and raw power associated with the 2-stroke outboard.

haha i was thinkin of them same two videos b4 i even opened this thread, anyways yeah etec basically is a direct injected 2 stroke engine, direct injection means the fuel is directly injected straight into the combustion chamber, etec uses voice coil injectors so the fuel doesn't have to be all pressured up in fuel ...

Not even close. E-TEC is a direct injection two-stroke system controlled by an engine management module. This means an exact amount of fuel is injected directly into the cylinder, thus lowering total emissions and protecting our precious air and water resources.
