Motoring solo is dangerous. It is much safer to sit on the front seat and motor the canoe stern first. Unfortunately, motor mounts aren’t long enough! We’ve solved the problem with this extension. Also, use it to add an extra motor to a square stern canoe. Maximum width is 30″. Both our Flipper and the Super Strong motor mounts are predrilled for this extension. It will also work on similar motor mounts with a wide flat bar. Will NOT work with Radisson motor mounts.
