It is an orginal Marine Engine(Steyr 236) not a converted one and taken out of Power Boat.
About the Turbo,it is double wall water called,which means there is shell outside the turbo which fresh water is cooling.Most of the Turbo Diesel marine engines has it.Fresh water is cooled by the sea/lake water.
propeller is still the dark horse. Calculations gives 49mph.
Does anyone know a propeller manufacturer?
