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 1):
A ship propulsion unit attached to an outside of a ship on a rear end side of a ship body, the ship propulsion unit comprising:\n an engine including a crankshaft extending in a front-rear direction of the ship; a propeller shaft disposed below the engine with respect to an up-down direction of the ship and having one end provided with a propeller; a power transmission mechanism configured to\n couple an output portion of the crankshaft extending from the engine toward the rear end side of the ship body and a coupling portion at an other end of the propeller shaft, and \n transmit driving force of the engine to the propeller shaft; \n an upper case accommodating the output portion of the crankshaft and an upper portion of the power transmission mechanism; and a lower case connected to a lower portion of the upper case with respect to the up-down direction of the ship, accommodating the propeller shaft such that the propeller is disposed outside, and accommodating a lower portion of the power transmission mechanism, the power transmission mechanism including a drive shaft that extends from the upper case toward the lower case, the upper case and the engine being fixed to the ship body, a connection portion between the upper case and the lower case being provided with a rotation mechanism configured to rotate the lower case relative to the upper case around an axis extending in an extending direction of the drive shaft.
