Hello all of you boat boys. I am a single mother who just bought my first boat. It is an older 80's 16 ft Vanguard with a 70hp Merc outboard. Small enough for me to load and unload by myself with ease and yet big enough and powerful enough to tow my boys around on a tube. I got a very good deal on the boat, but...I got a good deal because the transom has rotted right out and has to be replaced...how do I do that? Where do I start?
