Python Drive P501-L Complete Shaft Drive System – for 3:1 Reverse Coupling, Shaft Diameter 60–80 mm, Max Torque 4900 Nm, Max Thrust 45 kN
The Python Drive P501-L Complete Shaft Drive System is designed for marine propulsion installationsrequiring high torque capacity and strong thrust management. The system is compatible with a3:1 reverse coupling and suitable for engines up to420 HP at 1900 RPM.
The drive unit supports shaft diameters from 60 to 80 mm and incorporates amaintenance-free CV joint drive shaft together with a large thrust bearing assembly.This configuration transfers propeller thrust smoothly to the hull while allowing the propeller shaftto rotate evenly even when operating at unequal shaft angles.
