Running on \u003cstrong\u003e12V or 24V DC\u003c\/strong\u003e, it delivers 3.0kW of power with outstanding durability and corrosion resistance. An exclusive Quick elastic coupling optimises motor-to-gearbox alignment, absorbing impulses and protecting the operating system. The four-blade composite propeller delivers maximum thrust with reduced current draw, and the bronze propeller gearleg features a hydrodynamic profile that minimises turbulence in both thrust directions. Maintenance-free design — highly resistant components guarantee a perfect lubrication seal for life. Overheating protection is managed via the touch panel or joystick panel software — no thermal sensor required.
