As Torqeedo Ultralight 403 owners, every time we go fishing we must attach the motor to our kayak. After the day is over we are then removing it. 
Why not do it easier rather than having to carry hex keys which are easy to loose. I have come up with an easier way! Replacing the M6 x2 bolt with a Threaded Adjustable Cam Lever this problem is solved.
What is a threaded adjustable cam Lever?
A threaded adjustable cam lever is made up of a handle with a cam attached to a threaded stud. On the Stud is a threaded washer a with a depression on one side. The cam action or elliptical shape will compress and tighten the threaded stud when the lever is pressed down. The fastener allows for quick fastening and removal without using tools.
Usage:
Attaching the Torqeedo:
Threaded Adjustable Cam Lever will replace the existing 5MM hex M6 x 2 bolt. Thread into existing nut. Insert the upper boom of the motor trim/mount into ball coupler. The threads do not have to be completely tight. Twist cam lever until snug. A simple pressing down motion of the lever will compress the thrust washer so the boom will not slip.
Detaching the Torqeedo:
Pull lever to upright position. Loosen a turn or two. Detach upper boom from ball coupler. Tighten cam lever and lock down not to loose it during transport.
