My new (April 2013) Terrova with I-Pilot popped up and launched itself when I was running about half speed at Steinhatchee, FL. I had been running all day and was returning to port after about an 8 mile run with a light (1 foot or less) chop. When the motor hit the water the force ripped the whole unit off the boat. I have run on rougher water at the lakes near home. Has anyone ever heard of this happening before? Could this be some kind of defect in the latch which holds it in place?
