Engine 

The engine fitted, as standard, is the Rotax 915 iS. This engine is a 4-

stroke, 4-cylinder, turbocharged, horizontally opposed, spark ignition 

engine, with one central camshaft -pushrod OHV and a displacement 

of 1211cc (1.2L/74 cubic inch). The engine makes use of liquid cooled 

cylinder heads with air cooled cylinders.  The lubrication system can 

be described as sump forced lubrication and the ignition makes use of 

dual contactless capacitor discharge magneto type ignition system, 

that is ECU controlled.  The engine is fitted with an electric starter 

motor, two AC alternators and two electric fuel pumps. The propeller 

is driven through a reduction gearbox, of ratio 2.52, and features an 

integrated shock absorber. The engine will continue to run after an 

alternator/battery failure. Please see 3.7.4 Alternator / Charge System 

Failure for more. 
Please refer to the 

latest revision 

of the manufacturer documentation 

(Operators Manual / Maintenance Manual) for more information.
