摘要： Propeller combination for an aft-mounted boat propeller drive unit with counter-rotating pushing propellers (8,9). The forward propeller (9) is made with blades (12) which have blade tips with an outer edge (b) which approaches a straight line. The width of the blade tip is between 40% and 45% of the maximum width of the blade.

摘要： A marine propeller drive (1) for boats, including a gearbox (10) for a motor transmission and an associated impelling propeller (12). The propeller (12) is provided with a propeller hub (14), the main peripheral cross-section dimension (A) of which is less than the main peripheral cross-section dimension (B) of the gearbox (10) and where a transition cone (18) is located between the gearbox (10) and the propeller hub (14). The transition cone (18) has a front end (20) located in connection with the gearbox (10), where the front end (20) has an initial peripheral cross-section dimension (C) essentially corresponding to the main peripheral cross-section dimension (B) of the gearbox (10). A rear end (22) of the cone is located in connection with the propeller hub (14), where the rear end (22) has a connecting peripheral cross-section dimension (D) essentially corresponding to the main peripheral cross-section dimension (A) of the propeller hub (14). The invention is distinguished in particular by the fact that the transition cone (18) includes a bulb-shaped shoulder part (24) located between the front end (20) and rear end (22), the largest peripheral cross-section dimension (E) of which exceeds the initial peripheral cross-section dimension (C) of the transition cone (18).

摘要： A propeller drive for boats features a transition cone between the gearbox housing and the propeller hub(s). The propeller hub (that is closest to the gearbox housing) is smaller in cross-sectional dimension than the gearbox housing. The dimension of the front end of the transition cone corresponds to the cross-sectional dimension of the gearbox housing, and the dimension of the rear end of the transition cone corresponds to the cross-section dimension of the (closest) propeller hub. The transition cone has a bulging shoulder between the front and rear ends, the largest peripheral cross-sectional dimension of which is greater than the cross-sectional dimension of the front of the transition cone.

摘要： Boat propeller drive unit with an underwater housing (5), which is solidly joined to a boat hull and has pulling propellers (15, 16) on the forward facing side of the housing. At the aft edge of the underwater housing, a rudder is mounted, comprising a first rudder blade (22a) mounted in the underwater housing and a second rudder blade (22c) mounted on the aft edge of the first rudder blade.
