Abstract
An outboard motor includes a power source, a boat propulsion section, a shift position switching mechanism, a clutch actuator, and a control device. The shift position switching mechanism switches among a first shift position in which a first clutch is engaged and a second clutch is disengaged, a second shift position in which the first clutch is disengaged and the second clutch is engaged, and a neutral position in which both the first clutch and the second clutch are disengaged. When a gear shift is to be made from the first shift position to the second shift position, the control section causes the clutch actuator to gradually increase an engagement force of the second clutch. The outboard motor reduces the load to be applied to the power source and the power transmission mechanism at the time of a gear shift in a boat propulsion system including an electronically controlled shift mechanism.
