I installed the first one in a gear track for my transducer arm this morning, and it twisted off and broke just below the ball as I hand tightened it down on the track. I thought it was just bad luck and a fluke break. I put a second one on went out on the water, lowered my transducer arm, and the second one snapped in the same place! Granted, the second one could have had a bit too much leverage on it cause the transducer mount was a bit tight, but I wasn't exactly muscling it. Anyone else had this issue? Two broken, same spot, within an hour.
