To provide a ship propulsion machine capable of detecting any excessive load on a shift mechanism with high accuracy.
The ship propulsion machine includes an engine, a drive shaft, a propeller shaft, a shift mechanism, an operational force transmission mechanism 41, and a magnetostrictive sensor 25. The drive shaft transmits the power from the engine. The propeller shaft is rotated and driven by the power transmitted from the drive shaft. The shift mechanism shifts the rotational direction of the power to be transmitted from the drive shaft to the propeller shaft. The operational force transmission mechanism is connected to the shift mechanism. The operational force transmission mechanism transmits the shift operational force for operating the shift mechanism to the shift mechanism. The magnetostrictive sensor senses the load on the operational force transmission mechanism.
