Outboard Motor Brackets

"An Outboard Bracket - The handiest way to equip a small sailboat with auxiliary power - or a fishing craft with a low-powered trolling engine - is to mount an outboard motor on the transom by means of a retractable bracket. This kind of bracket allows the boatman to lift the motor out of the water when it is not in use without removing it from the bracket." - Time/Life Library of Boating
