As the title shows I am thinking about purchasing my first boat. I would like a fishing/family oriented boat. Two that I have been looking at are the tracker pro guide v175 combo with a 115hp mercury, the second is a nitro z19 sport with a 150hp mercury. I live in Michigan so we have a big mix of small and large lakes. Would like something big enough to take in the bays of the Great Lakes but yet small enough for the smaller lakes. Also would like a boat that I could use for tubing. Any advise is appreciated. As I said, this would be my first boat so I am pretty clueless.
