An outboard motor includes an outboard-motor main-body, an anti-ventilation plate, and a foreign-matter collection apparatus. The anti-ventilation plate is provided on the outboard-motor main-body. The foreign-matter collection apparatus is provided above the anti-ventilation plate and outside the outboard-motor main-body and located at a height such that a water intake is submerged under water when a ship to which the outboard-motor main-body has been attached is in a pre-planing state.
