Abstract
A vessel propulsion apparatus includes a prime mover, a propeller shaft, a planetary gear train, a lower case, a cylindrical housing, and a fixing member. The planetary gear train is disposed on a propeller axis. The propeller shaft and the planetary gear train are housed in the lower case. The housing surrounds the propeller shaft about the propeller axis inside the lower case. The housing supports a sun gear such that the sun gear is not rotatable with respect to the housing. The fixing member is fixed to both the lower case and the housing.
