Abstract

An outboard engine unit, where a drive shaft is connected to an engine and rotatably supported in a drive shaft chamber via a bearing and where a gear mechanism for transmitting rotation of the drive shaft to a propeller shaft is accommodated in a gear chamber, includes: a lubricant circulation section for returning lubricant oil, having lubricated the bearing, back to the gear chamber; an oil storage chamber for receiving the lubricant oil having lubricated the bearing; and a return passage communicating the oil storage chamber with the gear chamber. The lubricant oil guided to the oil storage chamber is returned back to the gear chamber via the return passage.
