1.6 ENGINE
The ROTAX
®
912 S3 is a 4-cylinder 4-stroke engine with air cooled cylinders and liquid cooled
cylinder heads.
The Propeller is driven via an internal reduction gearbox with an integrated overload clutch and
a hydraulic constant speed propeller governor.

(1352 cm³)
max. Takeoff power (5 min.):
98.6 BHP
(73.5 kW)
at max. Takeoff propeller speed:
2385 RPM
max. continuous power:
92.5 BHP
(69.0 kW)
at max. continuous propeller speed:
2260 RPM
1.7 PROPELLER
Hydraulic two-blade, constant speed propeller
Manufacturer:
mt-Propeller
Type:
MTV-21-A/170-05

1.8 FUEL
The following fuel grades are approved for use (min. RON 95):
EN228 Super
ASTM D4814
EN228 Super plus
AVGAS 100LL
ASTM D910
AVGAS UL 91
ASTM D7547
Left Fuel Tank
Right Fuel Tank
Fuel Capacity (total):
15.8 US gal (60 l)
15.8 US gal (60 l)
Usable Fuel (total): 14.48 US gal (54.8 l)
14.48 US gal (54.8 l)
Unusable Fuel:
1.37 US gal (5.2 l)
1.37 US gal (5.2 l)
Due to the higher lead content in AVGAS 100LL, wear of the valve seats, deposits in the
combustion chamber and lead sediments in the lubrication system will increase when using this
type of fuel. Therefore AVGAS should only be used if you encounter problems with vapor lock
or if the other fuel types are not available.
Lead free AVGAS UL 91 is similar to AVGAS 100LL (MON 91
⇒
RON > 95) when it comes to
vapor lock susceptibility. However, it does not suffer from lead induced problems.
(Please refer to the current issue of the operating manual for the ROTAX
912 engine series)
