Light Sport Information

There are Pros and Cons for this engine:

Pros: 
 - A lot of Rotax’s are in use with very little problems.
 - Because it’s water cooled, you can have a heater in the cockpit.

Cons:
 - Water cooled, more complex - Just another thing to fail.
 - Reduction gear is needed to reduce the 5300 RPM to 2600 RPM for the propeller.
