Abstract
The propeller device (10,30) comprises a propeller nozzle (12,32), inside which is arranged a propeller (14,34) driven by a propeller shaft (22,42). In front of the propeller (14,34), arranged to rotate inside the propeller nozzle (12,32), is arranged a front piece (16,36) acting as an ice crusher and provided with blades (17,37) or corresp. extensions. The front piece is arranged to rotate on the same rotational shaft (S-S) as the propeller (14,34). The front piece (16,36) acting as an ice crusher, and provided with blades (17,37) or corresp. extensions, is provided with a drive.
