摘要： In an outboard motor having a power transmission mechanism for transmitting power of an engine to a propeller, the power transmission mechanism has a transmission ratio changing unit having a transmission ratio changing planetary gear train including a transmission ratio changing sun gear, transmission ratio changing planetary gears, and a transmission ratio changing internal gear. The transmission ratio changing internal gear is connected to an input side shaft on the engine side. The transmission ratio changing planetary gears are connected to an output side shaft on the propeller side. The transmission ratio changing sun gear is connected to a stationary portion via a one-way clutch. The transmission ratio changing planetary gears and the transmission ratio changing internal gear and/or the transmission ratio changing sun gear are connected by an on-off clutch. When the on-off clutch is disengaged, the one-way clutch is engaged and the speed from the input side shaft is outputted from the output side shaft with a reduced speed. When the on-off clutch is engaged, the one-way clutch is disengaged and the speed from the input side shaft is outputted from the output side shaft with the same speed.
