I have a big boat that is a pain to use. 19 ft I/O. I want a small boat to put in local lakes and take my grandson fishing. My neighbor has a 14 ft aluminum fishing boat and trailer he will sell cheap. No motor though. He used an electric tiller motor, I am trying to decide between that and a small gas motor. I want it to be light enough to carry easy. This will be used on small lakes 2-3 miles across. I am thinking a 4-10 hp or electric. What do you think?
