Light-Sport Chronicles: Snowmobile Engine...NOT!
Kicking the Rotax myth in the head once and for all
In case you're new to the game, a recap: Rotax, an Austrian company, is owned by Canada-based BRP (Bombardier Recreational Products). Over the last 50 years, Rotax has created more than 350 designs and built more than 7,000,000 engines! Rotaxes power snowmobiles, Sea-Doo and other watercraft, all-terrain vehicles, motorcycles and go-karts and, of course, certified S-LSA, experimental and ultralight aircraft.
So why does the "snowmobile" smackdown persist? Good question when you consider:
- The vast majority of the 120 ASTM-approved S-LSA models use Rotax engines. Most are water-cooled four-strokes, known as the "9" series (912ULS, 914, etc.).
- Rotax also has FAA-certified the "9" series to FAR Part 33 standards. They're standard on Diamond's HK36 Super Dimona, Tecnam's P2008 certified twin and the Stemme S10 motorglider.
- All new "9" series engines are TBO'd (time between overhauls) at 2,000 hours.
