Trolling Motor Rudder

[Therapist]

How about a piece of Schedule 40 PVC, cut in half to fit against the motor. The rudder can then be pop riveted to the PVC, and the hose clamps can attach the whole thing to your motor. You can also "flange" the rudder, cut a slot in the PVC and slide the rudder through the slot, then clamp it to the motor. Thinking that the rudder does not have to be that thick, 1/8th should do the trick.
