An outboard drive device (10) comprising a motor (11) having a crankshaft (16), wherein said outboard drive device (10) further comprises a propeller shaft (12) with a propeller which propeller is below the hull (13) of a boat when said outboard drive device (10) is operated, and a power coupling system for transferring power from the motor (11) to the propeller shaft (12). The motor (11) is an automotive motor or an industrial base engine, wherein the crankshaft (16) is substantially horizontal and substantially parallel to the propeller shaft (12) when said outboard drive device (10) is operated. The power coupling system comprises a power transfer device (17), a transmission (18) and a transmission drive shaft (19). The power transfer device (17) connects the crankshaft (16) with the transmission drive shaft (19) for transferring the output power from the crankshaft (16) to the transmission drive shaft (19). The transmission (18) comprises a forward gear (23) and a reverse gear (24), so that the output power is reversible. |

1. An outboard drive device comprising a motor having a crankshaft, wherein said outboard drive device further comprises a propeller shaft with a propeller which is below the hull of a boat when said outboard drive device is operated, and a power coupling system for transferring power from the motor to the propeller shaft, wherein the crankshaft is substantially horizontal and substantially parallel to the propeller shaft, the power coupling system comprises a power transfer device, a transmission and a transmission drive shaft, the power transfer device connects the crankshaft with the transmission drive shaft for transferring the output power from the crankshaft to the transmission drive shaft, the transmission comprises a forward gear and a reverse gear, so that the output power is reversible, the transmission is arranged below the motor and between the crankshaft and the propeller shaft; and wherein the transmission further comprises a clutch centrally oriented between the forward and reverse gears, wherein the clutch is vertically aligned with a segment of said propeller shaft operatively coupled to the power coupling system, wherein the crankshaft extends in line with a longitudinal direction of the boat when said outboard drive device is mounted to the boat, whereby the crankshaft is configured to vary from such in-line orientation only when the boat is to be steered, said crankshaft and propeller shaft being substantially horizontal and substantially parallel when the boat is so steered. |
