Abstract:
A ship propulsion unit includes: an engine including a crankshaft extending in a front-rear direction of a ship; a propeller shaft; a power transmission mechanism configured to couple the crankshaft and the propeller shaft; an upper case; and a lower case accommodating the propeller shaft and connected to the upper case. The power transmission mechanism includes a drive shaft extending from the upper case toward the lower case. The upper case and the engine are fixed to a ship body. A connection portion between the upper case and the lower case is provided with a rotation mechanism configured to rotate the lower case around an axis of the drive shaft.

Claim (Index 2):
The ship propulsion unit according to  claim 1 , wherein\n the power transmission mechanism includes a first power transmission portion, a middle shaft, a second power transmission portion, the drive shaft, and a third power transmission portion that are provided sequentially from an engine side on a power transmission path extending from the engine side to the propeller shaft, the middle shaft is provided between the crankshaft and the propeller shaft in the up-down direction of the ship, and extends in parallel with a rotation axis of the crankshaft, the drive shaft is provided between the middle shaft and the propeller shaft in the up-down direction of the ship, and extends from the middle shaft toward the propeller shaft, the first power transmission portion is configured to transmit, to the middle shaft, the driving force from the engine output to the output portion of the crankshaft, the second power transmission portion is configured to transmit, to the drive shaft, the driving force from the engine transmitted to the middle shaft, and the third power transmission portion is configured to transmit, to the propeller shaft, the driving force from the engine transmitted to the drive shaft.
