TODAY’S PATENT – L-DRIVE
The invention L-DRIVE was invented by David D. Jones (Mequon, WI) on 13th of March 1990, bearing the patent number US4907994A.
The field of the present invention relates to a boat propulsion device and more particularly concerns a propeller drive for mounting from a hole in the bottom of a boat which is swingable under the boat for steering and for trimming/tilting of the drive.
In the present invention a boat propulsion device is mounted through a raised bottom surface of a boat. The propulsion device includes a drive under and extending to the rear of the boat which steers and trim/tilts. Steering is done by swinging the drive side to side and trimming is done by swinging the drive up and down.

This invention aims to reduce the complexity of previous drives while needing less parts and providing equivalent or superior operation.
