Patriot Boost Snowmobile Engine | Polaris Snowmobiles

More Power. Everywhere.

As the most powerful engine from Polaris, experience the thrill and all out speed and power whether you're riding in the backcountry, the trails, or the lakes.

Power from Sea to Summit

The Patriot Boost produces 10% more power at sea level & 50% more power at 10,000 feet than 850 Patriot. Plus, it maintains power up to 2,000 feet higher than the competition*.

Immediate Response

The Patriot Boost features a unique reed valve in the boost box. The reed valve allows air to enter the engine while the turbo is building boost, delivering immediate response with turbocharged power.

Developed to be Boosted

From the very first sketch, the 850 Patriot was designed to be boosted. The result is the most powerful Polaris engine, the factory 2-stroke turbocharged Patriot Boost.
