My son owns one now and I did own one on a boat I sold recently (55# PD V2 ie. I-pilot). My son has a 17' semi V tracker and he has had no problems with the tm spinning around but I was running one on a flat bottom carolina skiff and it gave me fits on breezey days loosing the gps signal (I assume) causing the tm to start spinning around. As far as cutting off...if I was trolling at say .8mph (usually running on #2 speed) and I hit the rabbit button it might cut off my tm and I figured it was from throwing such a heavy load on the tm all of a sudden. Again, my son's doesnt do this...his works fine. Neither of us had problems with cables getting too hot/melting though.
