Well I think I did it. I used two, inch and a half clamps that you use to hold fish nets etc. Then I mounted them to some alum. flat stock,ground the screws down after I put them on. Wire tied the extra cable too the bar. Now it snaps on when the motor is in the water,and when its stowed I can snap it on the shaft for transport. I used the trolling motor for the first time today,WOW WOW! I can sit in my chair and with the remote,move to the back and still control it.
If you like send me an email and I will try to get pics out.
