An improved exhaust system and bearing arrangement for a small displacement outboard motor that is rotatable through substantially 360 degrees for reverse operation. The drive shaft housing is formed with a reduced diameter cylindrical portion that is journaled within the swivel bracket by a bearing arrangement comprised of plastic elements and O-ring elements. The engine has an exhaust system with an exhaust pipe that at least in part encircles the drive shaft and which extends into the drive shaft housing below at least one the bearings to provide sufficient length for tuning and to avoid undue heating of the bearing. |
