and an operating rod whose tip end is fixed to the clutch actuating rod drive cam , a forward drive pawl is provided on the forward driven gear side of the clutch member, and a forward driving pawl is provided on the reverse driven gear side of the clutch member. A reverse drive pawl is provided, and a forward drive pawl engaging portion is provided at a portion of the forward driven gear that faces the forward drive pawl of the clutch member, and a forward drive pawl engaging portion faces the reverse drive pawl of the clutch member. In the forward/reverse switching mechanism for an outboard motor, the reverse driven gear is provided with a reverse drive pawl engaging portion, and the clutch actuation rod drive cam has two cam surfaces equally spaced and parallel to each other. A cam engaging portion is formed at the tip of the clutch actuating rod , and is constantly engaged with both of the cam surfaces and moves in accordance with the cam surfaces as the clutch actuating rod drive cam operates. This is a forward/reverse switching mechanism for outboard motors.
