I need a new trolling motor. I bought the boat last year with a 42lb motorguide on it and it is either really tired, or just flat out not big enough. I'm not looking at spending a lot of money, so the big $1000 motors are out of the question. Would a 55lb get the job done? I would be using it to troll around weedbeds on lakes, not for holding a position on a river or vertically jigging.
