So we are out on the lake last weekend, and i smell smoke... then a smelly hot plastic smell. We had just finished trolling for some slabs & were headed to another spot. I seen smoke coming from the troll motor... it shorted out melted all the wiring, NOT fun. soooo needless to say i am wanting to buy a new one. I am unfamiliar with them (this one came with the boat) so please help me choose a good powerful model. IF you were to buy one for yourself....what would you get. We do alot of trolling. Bow mounted of course.
