For the right choice of a Python-Drive, compute as following :

		Max Power of the engine (kW)	or ---->			Max Power of the engine (HP)
divide	/	Max rpm ( n )		divide	/	Max. rpm ( n )
multiply	x	9680		multiply	x	726
multiply	x	Reduction of Gearbox		multiply	x	Reduction of Gearbox
	___	_______________________________				_______________________________
result	=	Torque (A in Nm)		result	=	Torque (A in Kgm)

Example: (135 HP : 2500 rpm ) x 726 x 2 (reduction Gearbox) = 78,4 Kgm ( Torque of prop shaft )
 

Further, the thrust of the prop may not exceed the value noticed in the technical data.

Units: 1 Kgm = 9,807 Nm, 1 PS = 0,736 kW , 1 kg = 9,807 N , 1 kN = 1.000 N
