0 likes857 views
This document provides specifications for the Yanmar 4LHA-STP marine diesel engine. It is a 4-stroke, turbocharged inline 4-cylinder engine with a displacement of 3.455 liters that produces up to 177 kW of power at 3300 rpm. It has a freshwater cooling system and enclosed lubrication system. Optional equipment includes different instrument panels, exhaust configurations, and marine gearboxes that can provide propeller speeds between 1976 rpm and 1230 rpm. Performance curves provide additional information on output, torque, fuel consumption, and recommended propeller sizes.
