ABSTRACT:
A combined propulsion and steering system for motor boats with inboard engines comprises a propeller shaft projecting from the lower part of the transom of the boat and carrying a semi-submerged propeller screw which is enclosed by an arch-like deflector tunnel extending over and to the sides of the said propeller screw and turnable about a substantially vertical axis. The ratio (L/D) between the distance (L) from the rear part of the propeller screw to the lower rear part of the transom hull and the outer diameter (D) of the propeller screw lies between 0.8 and 1.8. There is also provided an engine exhaust gas duct, forwardly of said propeller screw.
