63 – 81 KW (86 – 110 HP)4-Cylinder

The state-of-the-art STEYR Marine Diesel Enginewith dual cooling circuit fulfilling the strengthenedfuture marine emission regulation.

The STEYR Marine Engine is designed for high performance.The innovative fuel injection technology enables an excellent torqueand speed range. Therefore adaptation to existing marine propulsionsystems can be performed easily.Remarkable features of the STEYR Marine Engines are the dynamicbehaviour and immediate response as well as the impressiveacceleration.

SERVICE LIFEThe STEYR Marine Engines are manufactured using high alloy materials toprovide enduring longevity for all running components. Using corrosionresistant materials for the entire seawater system as a standard in the dualcircuit cooling system. Consequently designed solutions to meet the criteriaof marine environment guarantee the best corrosion protection for anyauxiliaries and electronic components in marine ambience.

COMFORT.The patented 2-stage UNIT INJECTOR fuel injection technology providesfor a worldwide approved and smooth operation noise (patented).Noise emission levels are over the most important operating range belowthe running noise of gasoline engines. The additional elastic separation ofthe Monoblock against the aluminum casted engine housing reduces theengine related vibration transmitted into the hull therefore the noise levelon board is further reduced.Torque and speed range characteristic enable optimal matching to individualapplication while maintaining transmission, gear ratio and propeller dimensions.The big choice of matched accessories fulfills the highest level of quality andcomfort for you on board your vessel.

EXHAUST EMISSIONSThe trend-setting UNIT INJECTOR system enables us already today toconform with the valid emission regulations BSO II and SAV 2, respectivelywe can fulfill the announced EPA – Tier 2 and suchlike emission regulations.

TRANSMISSIONSteyr Marine Engines allow the installation with different driving system inyour boot. Adaptation for ZF – marine transmission with different output

configuration (direct, horizontal down-angle 8°, V-drive 12°), to choose fromas well as an intermediate housing for propeller shaft and Jet-Drives and kitsfor installation to Mercury Bravo I, Bravo II and Bravo III Stern-Drives.

TECHNICAL DESCRIPTIONENGINE MONOBLOCKOur unique and robust monoblock design, engine block and cylinder headmade from high grade alloy cast iron, without limitation in cooling andunrivaled roundness of the cylinder gives exceptional life time for the liner.• Chrome-Molybdenum forged crankshaft, dynamically balanced• Pistons are cast from high silicon aluminum, with oil cooling channel in

Dual alternators optional

120 KW (163 HP)rated speed 2800 rpm6-Cylinder

The state-of-the-art STEYR Marine Diesel Enginewith dual cooling circuit fulfilling the strengthenedfuture marine emission regulation.

The STEYR Marine Engine 166 is designed for high performance.The innovative fuel injection technology enables an excellent torqueand speed range. Therefore adaptation to existing marine propulsionsystems can be performed easily.Remarkable features of the STEYR Marine Engines are the dynamicbehaviour and immediate response as well as the impressiveacceleration.

SERVICE LIFEThe STEYR Marine Engines are manufactured using high alloy materials toprovide enduring longevity for all running components. Using corrosionresistant materials for the entire seawater system as a standard in the dualcircuit cooling system. Consequently designed solutions to meet the criteriaof marine environment guarantee the best corrosion protection for anyauxiliaries and electronic components in marine ambience.

COMFORT.The patented 2-stage UNIT INJECTOR fuel injection technology providesfor a worldwide approved and smooth operation noise (patented).Noise emission levels are over the most important operating range belowthe running noise of gasoline engines. The additional elastic separation ofthe Monoblock against the aluminum casted engine housing reduces theengine related vibration transmitted into the hull therefore the noise levelon board is further reduced.Torque and speed range characteristic enable optimal matching to individualapplication while maintaining transmission, gear ratio and propeller dimensions.The big choice of matched accessories fulfills the highest level of quality andcomfort for you on board your vessel.

EXHAUST EMISSIONSThe trend-setting UNIT INJECTOR system enables us already today toconform with the valid emission regulations BSO II and SAV 2, respectivelywe can fulfill the announced EPA – Tier 2 and suchlike emission regulations.

TRANSMISSIONSteyr Marine Engines allow the installation with different driving system inyour boot. Adaptation for ZF – marine transmission with different output

configuration (direct, horizontal down-angle 8°, V-drive 12°), to choose fromas well as an intermediate housing for propeller shaft and Jet-Drives and kitsfor installation to Mercury Bravo I, Bravo II and Bravo III Stern-Drives.

TECHNICAL DESCRIPTIONENGINE MONOBLOCKOur unique and robust monoblock design, engine block and cylinder headmade from high grade alloy cast iron, without limitation in cooling andunrivaled roundness of the cylinder gives exceptional life time for the liner.• Chrome-Molybdenum forged crankshaft, dynamically balanced• Pistons are cast from high silicon aluminum, with oil cooling channel in

3-ring technology• Hardened valve-seats high performance NIMONIC valve material• Elastic coupling on flywheel, design matched depending on application

ENGINE MOUNTINGAdjustable front and rear silent blocks capable to take propeller thrust.

106 – 120 KW (144 – 163 HP)4-Cylinder

The state-of-the-art STEYR Marine Diesel Enginewith dual cooling circuit fulfilling the strengthenedfuture marine emission regulation.

The STEYR Marine Engine is designed for high performance.The innovative fuel injection technology enables an excellent torqueand speed range. Therefore adaptation to existing marine propulsionsystems can be performed easily.Remarkable features of the STEYR Marine Engines are the dynamicbehaviour and immediate response as well as the impressiveacceleration.

SERVICE LIFEThe STEYR Marine Engines are manufactured using high alloy materials toprovide enduring longevity for all running components. Using corrosionresistant materials for the entire seawater system as a standard in the dualcircuit cooling system. Consequently designed solutions to meet the criteriaof marine environment guarantee the best corrosion protection for anyauxiliaries and electronic components in marine ambience.

COMFORT.The patented 2-stage UNIT INJECTOR fuel injection technology providesfor a worldwide approved and smooth operation noise (patented).Noise emission levels are over the most important operating range belowthe running noise of gasoline engines. The additional elastic separation ofthe Monoblock against the aluminum casted engine housing reduces theengine related vibration transmitted into the hull therefore the noise levelon board is further reduced.Torque and speed range characteristic enable optimal matching to individualapplication while maintaining transmission, gear ratio and propeller dimensions.The big choice of matched accessories fulfills the highest level of quality andcomfort for you on board your vessel.

EXHAUST EMISSIONSThe trend-setting UNIT INJECTOR system enables us already today toconform with the valid emission regulations BSO II and SAV 2, respectivelywe can fulfill the announced EPA – Tier 2 and suchlike emission regulations.

TRANSMISSIONSteyr Marine Engines and MerCruiser Stern-Drives are an ideal combinationfor your power boat. STEYR and MerCruiser put together an optimum

package for best performance and offers you for your enjoyment STEYRengines with Bravo I, Bravo II and Bravo III Stern-Drives.
