What type of outboard motor can be installed on an inflatable boat?

Short shaft 15″ outboard motors are recommended to be installed on the 15″ transom of an inflatable boats. The lighter the outboard motor – the better. Either 2-stroke or 4-stroke engines may be installed on a boat transom, however 2-stroke engines are generally much lighter then 4-stroke outboard motors.

Long shaft 20″ motors are not recommended, but may also be installed if a short shaft o/b is unavailable. However a long shaft o/b may create extra underwater drag. Long shaft o/b may be raised a few inches with the help of a 2-3″ wooden bar placed on top of the boat’s transom.
