<p>The propeller tail is intended to be applied to yachts, fishing boats and the like, and is designed to be mounted either internally or externally with respect to the boat itself. The propeller tail structure is based on two truncated groups (11 and 12), the first truncated group being associated to a crown (9) which receives the attack of a gear which moves through the corresponding motor so that the upper truncated group (11) transmits, by means of an axial connection shaft (13), the motion to the lowering truncated group (12) in order to transmit by means of another crown (23) the rotation to the shaft (21) on which is mounted the corresponding propeller (6), all of which being complemented by a rotation system based on a hydraulic rack (28) which is immersed in oil and which is in mesh with a crown (27) so that the final reduction selected from the motor-shift unit to the propeller (6) is achieved through the truncated groups (11 and 12).</p> |
